-## A message from the author
-
-> The original goal of Bolt was to provide a simple pure Go key/value store and to
-> not bloat the code with extraneous features. To that end, the project has been
-> a success. However, this limited scope also means that the project is complete.
-> 
-> Maintaining an open source database requires an immense amount of time and energy.
-> Changes to the code can have unintended and sometimes catastrophic effects so
-> even simple changes require hours and hours of careful testing and validation.
->
-> Unfortunately I no longer have the time or energy to continue this work. Bolt is
-> in a stable state and has years of successful production use. As such, I feel that
-> leaving it in its current state is the most prudent course of action.
->
-> If you are interested in using a more featureful version of Bolt, I suggest that
-> you look at the CoreOS fork called [bbolt](https://github.com/coreos/bbolt).

+## How to contribute
+
+While bug fixes can first be identified via an "issue", that is not required.
+It's ok to just open up a PR with the fix, but make sure you include the same
+information you would have included in an issue - like how to reproduce it.
+
+PRs for new features should include some background on what use cases the
+new code is trying to address. When possible and when it makes sense, try to
+break-up larger PRs into smaller ones - it's easier to review smaller
+code changes. But only if those smaller ones make sense as stand-alone PRs.
+
+Regardless of the type of PR, all PRs should include:
+* well documented code changes
+* additional testcases. Ideally, they should fail w/o your code change applied
+* documentation changes
+
+Squash your commits into logical pieces of work that might want to be reviewed
+separate from the rest of the PRs. Ideally, each commit should implement a
+single idea, and the PR branch should pass the tests at every commit. GitHub
+makes it easy to review the cumulative effect of many commits; so, when in
+doubt, use smaller commits.
+
+PRs that fix issues should include a reference like `Closes #XXXX` in the
+commit message so that github will automatically close the referenced issue
+when the PR is merged.
+
+Contributors must assert that they are in compliance with the [Developer
+Certificate of Origin 1.1](http://developercertificate.org/). This is achieved
+by adding a "Signed-off-by" line containing the contributor's name and e-mail
+to every commit message. Your signature certifies that you wrote the patch or
+otherwise have the right to pass it on as an open-source patch.

 The `ns.Do()` method provides **partial** control over network namespaces for you by implementing these strategies. All code dependent on a particular network namespace (including the root namespace) should be wrapped in the `ns.Do()` method to ensure the correct namespace is selected for the duration of your code.  For example:
 
 ```go

-Note this requirement to wrap every network call is very onerous - any libraries you call might call out to network services such as DNS, and all such calls need to be protected after you call `ns.Do()`. All goroutines spawned from within the `ns.Do` will not inherit the new namespace. The CNI plugins all exit very soon after calling `ns.Do()` which helps to minimize the problem.

-When a new thread is spawned in Linux, it inherits the namepaces of its parent. In versions of go **prior to 1.10**, if the runtime spawns a new OS thread, it picks the parent randomly. If the chosen parent thread has been moved to a new namespace (even temporarily), the new OS thread will be permanently "stuck in the wrong namespace", and goroutines will non-deterministically switch namespaces as they are rescheduled.
-
-In short, **there was no safe way to change network namespaces, even temporarily, from within a long-lived, multithreaded Go process**. If you wish to do this, you must use go 1.10 or greater. 
-

-### Creating network namespaces
-Earlier versions of this library managed namespace creation, but as CNI does not actually utilize this feature (and it was essentialy unmaintained), it was removed. If you're writing a container runtime, you should implement namespace management yourself. However, there are some gotchas when doing so, especially around handling `/var/run/netns`. A reasonably correct reference implementation, borrowed from `rkt`, can be found in `pkg/testutils/netns_linux.go` if you're in need of a source of inspiration.
+Also:  If the runtime spawns a new OS thread, it will inherit the network namespace of the parent thread, which may have been temporarily switched, and thus the new OS thread will be permanently "stuck in the wrong namespace".
 
+In short, **there is no safe way to change network namespaces from within a long-lived, multithreaded Go process**.  If your daemon process needs to be namespace aware, consider spawning a separate process (like a CNI plugin) for each namespace.

-// Package context provides several utilities for working with
-// golang.org/x/net/context in http requests. Primarily, the focus is on
-// logging relevant request information but this package is not limited to
-// that purpose.
-//
-// The easiest way to get started is to get the background context:
-//
-// 	ctx := context.Background()
-//
-// The returned context should be passed around your application and be the
-// root of all other context instances. If the application has a version, this
-// line should be called before anything else:
-//
-// 	ctx := context.WithVersion(context.Background(), version)
-//
-// The above will store the version in the context and will be available to
-// the logger.
-//
-// Logging
-//
-// The most useful aspect of this package is GetLogger. This function takes
-// any context.Context interface and returns the current logger from the
-// context. Canonical usage looks like this:
-//
-// 	GetLogger(ctx).Infof("something interesting happened")
-//
-// GetLogger also takes optional key arguments. The keys will be looked up in
-// the context and reported with the logger. The following example would
-// return a logger that prints the version with each log message:
-//
-// 	ctx := context.Context(context.Background(), "version", version)
-// 	GetLogger(ctx, "version").Infof("this log message has a version field")
-//
-// The above would print out a log message like this:
-//
-// 	INFO[0000] this log message has a version field        version=v2.0.0-alpha.2.m
-//
-// When used with WithLogger, we gain the ability to decorate the context with
-// loggers that have information from disparate parts of the call stack.
-// Following from the version example, we can build a new context with the
-// configured logger such that we always print the version field:
-//
-// 	ctx = WithLogger(ctx, GetLogger(ctx, "version"))
-//
-// Since the logger has been pushed to the context, we can now get the version
-// field for free with our log messages. Future calls to GetLogger on the new
-// context will have the version field:
-//
-// 	GetLogger(ctx).Infof("this log message has a version field")
-//
-// This becomes more powerful when we start stacking loggers. Let's say we
-// have the version logger from above but also want a request id. Using the
-// context above, in our request scoped function, we place another logger in
-// the context:
-//
-// 	ctx = context.WithValue(ctx, "http.request.id", "unique id") // called when building request context
-// 	ctx = WithLogger(ctx, GetLogger(ctx, "http.request.id"))
-//
-// When GetLogger is called on the new context, "http.request.id" will be
-// included as a logger field, along with the original "version" field:
-//
-// 	INFO[0000] this log message has a version field        http.request.id=unique id version=v2.0.0-alpha.2.m
-//
-// Note that this only affects the new context, the previous context, with the
-// version field, can be used independently. Put another way, the new logger,
-// added to the request context, is unique to that context and can have
-// request scoped variables.
-//
-// HTTP Requests
-//
-// This package also contains several methods for working with http requests.
-// The concepts are very similar to those described above. We simply place the
-// request in the context using WithRequest. This makes the request variables
-// available. GetRequestLogger can then be called to get request specific
-// variables in a log line:
-//
-// 	ctx = WithRequest(ctx, req)
-// 	GetRequestLogger(ctx).Infof("request variables")
-//
-// Like above, if we want to include the request data in all log messages in
-// the context, we push the logger to a new context and use that one:
-//
-// 	ctx = WithLogger(ctx, GetRequestLogger(ctx))
-//
-// The concept is fairly powerful and ensures that calls throughout the stack
-// can be traced in log messages. Using the fields like "http.request.id", one
-// can analyze call flow for a particular request with a simple grep of the
-// logs.

-// WithTrace allocates a traced timing span in a new context. This allows a

-## About
-
-This directory contains a collection of scripts used to build and manage this
-repository. If there are any issues regarding the intention of a particular
-script (or even part of a certain script), please reach out to us.
-It may help us either refine our current scripts, or add on new ones
-that are appropriate for a given use case.
-
-## DinD (dind.sh)
-
-DinD is a wrapper script which allows Docker to be run inside a Docker
-container. DinD requires the container to
-be run with privileged mode enabled.
-
-## Generate Authors (generate-authors.sh)
-
-Generates AUTHORS; a file with all the names and corresponding emails of
-individual contributors. AUTHORS can be found in the home directory of
-this repository.
-
-## Make
-
-There are two make files, each with different extensions. Neither are supposed
-to be called directly; only invoke `make`. Both scripts run inside a Docker
-container.
-
-### make.ps1
-
-- The Windows native build script that uses PowerShell semantics; it is limited
-unlike `hack\make.sh` since it does not provide support for the full set of
-operations provided by the Linux counterpart, `make.sh`. However, `make.ps1`
-does provide support for local Windows development and Windows to Windows CI.
-More information is found within `make.ps1` by the author, @jhowardmsft
-
-### make.sh
-
-- Referenced via `make test` when running tests on a local machine,
-or directly referenced when running tests inside a Docker development container.  
-- When running on a local machine, `make test` to run all tests found in
-`test`, `test-unit`, `test-integration`, and `test-docker-py` on
-your local machine. The default timeout is set in `make.sh` to 60 minutes
-(`${TIMEOUT:=60m}`), since it currently takes up to an hour to run
-all of the tests.
-- When running inside a Docker development container, `hack/make.sh` does
-not have a single target that runs all the tests. You need to provide a
-single command line with multiple targets that performs the same thing.
-An example referenced from [Run targets inside a development container](https://docs.docker.com/opensource/project/test-and-docs/#run-targets-inside-a-development-container): `root@5f8630b873fe:/go/src/github.com/moby/moby# hack/make.sh dynbinary binary cross test-unit test-integration test-docker-py`
-- For more information related to testing outside the scope of this README,
-refer to
-[Run tests and test documentation](https://docs.docker.com/opensource/project/test-and-docs/)
-
-## Release (release.sh)
-
-Releases any bundles built by `make` on a public AWS S3 bucket.
-For information regarding configuration, please view `release.sh`.
-
-## Vendor (vendor.sh)
-
-A shell script that is a wrapper around Vndr. For information on how to use
-this, please refer to [vndr's README](https://github.com/LK4D4/vndr/blob/master/README.md)

-# Integration Testing on Swarm
-
-IT on Swarm allows you to execute integration test in parallel across a Docker Swarm cluster
-
-## Architecture
-
-### Master service
-
-  - Works as a funker caller
-  - Calls a worker funker (`-worker-service`) with a chunk of `-check.f` filter strings (passed as a file via `-input` flag, typically `/mnt/input`)
-
-### Worker service
-
-  - Works as a funker callee
-  - Executes an equivalent of `TESTFLAGS=-check.f TestFoo|TestBar|TestBaz ... make test-integration-cli` using the bind-mounted API socket (`docker.sock`)
-
-### Client
-
-  - Controls master and workers via `docker stack`
-  - No need to have a local daemon
-
-Typically, the master and workers are supposed to be running on a cloud environment,
-while the client is supposed to be running on a laptop, e.g. Docker for Mac/Windows.
-
-## Requirement
-
-  - Docker daemon 1.13 or later
-  - Private registry for distributed execution with multiple nodes
-
-## Usage
-
-### Step 1: Prepare images
-
-    $ make build-integration-cli-on-swarm
-
-Following environment variables are known to work in this step:
-
- - `BUILDFLAGS`
- - `DOCKER_INCREMENTAL_BINARY`
-
-Note: during the transition into Moby Project, you might need to create a symbolic link `$GOPATH/src/github.com/docker/docker` to `$GOPATH/src/github.com/moby/moby`. 
-
-### Step 2: Execute tests
-
-    $ ./hack/integration-cli-on-swarm/integration-cli-on-swarm -replicas 40 -push-worker-image YOUR_REGISTRY.EXAMPLE.COM/integration-cli-worker:latest 
-
-Following environment variables are known to work in this step:
-
- - `DOCKER_GRAPHDRIVER`
- - `DOCKER_EXPERIMENTAL`
-
-#### Flags
-
-Basic flags:
-
- - `-replicas N`: the number of worker service replicas. i.e. degree of parallelism.
- - `-chunks N`: the number of chunks. By default, `chunks` == `replicas`.
- - `-push-worker-image REGISTRY/IMAGE:TAG`: push the worker image to the registry. Note that if you have only single node and hence you do not need a private registry, you do not need to specify `-push-worker-image`.
-
-Experimental flags for mitigating makespan nonuniformity:
-
- - `-shuffle`: Shuffle the test filter strings
-
-Flags for debugging IT on Swarm itself:
-
- - `-rand-seed N`: the random seed. This flag is useful for deterministic replaying. By default(0), the timestamp is used.
- - `-filters-file FILE`: the file contains `-check.f` strings. By default, the file is automatically generated.
- - `-dry-run`: skip the actual workload
- - `keep-executor`: do not auto-remove executor containers, which is used for running privileged programs on Swarm

+## Packages and input paths ##
+
+The protocol buffer language has a concept of "packages" which does not
+correspond well to the Go notion of packages. In generated Go code,
+each source `.proto` file is associated with a single Go package. The
+name and import path for this package is specified with the `go_package`
+proto option:
+
+	option go_package = "github.com/gogo/protobuf/types";
+
+The protocol buffer compiler will attempt to derive a package name and
+import path if a `go_package` option is not present, but it is
+best to always specify one explicitly.
+
+There is a one-to-one relationship between source `.proto` files and
+generated `.pb.go` files, but any number of `.pb.go` files may be
+contained in the same Go package.
+
+The output name of a generated file is produced by replacing the
+`.proto` suffix with `.pb.go` (e.g., `foo.proto` produces `foo.pb.go`).
+However, the output directory is selected in one of two ways.  Let
+us say we have `inputs/x.proto` with a `go_package` option of
+`github.com/golang/protobuf/p`. The corresponding output file may
+be:
+
+- Relative to the import path:
+
+	protoc --gogo_out=. inputs/x.proto
+	# writes ./github.com/gogo/protobuf/p/x.pb.go
+
+  (This can work well with `--gogo_out=$GOPATH`.)
+
+- Relative to the input file:

+	protoc --gogo_out=paths=source_relative:. inputs/x.proto

+//
+// - If an http annotation is inherited, the path pattern will be
+//   modified as follows. Any version prefix will be replaced by the
+//   version of the including interface plus the [root][] path if
+//   specified.

+//     package google.acl.v1;

+//       // Get the underlying ACL object.

+// Example of a mixin configuration:
+//
+//     apis:
+//     - name: google.storage.v2.Storage
+//       mixins:
+//       - name: google.acl.v1.AccessControl
+//
+// The mixin construct implies that all methods in `AccessControl` are
+// also declared with same name and request/response types in
+// `Storage`. A documentation generator or annotation processor will
+// see the effective `Storage.GetAcl` method after inherting
+// documentation and annotations as follows:
+//
+//     service Storage {
+//       // Get the underlying ACL object.

+//       }
+//       ...
+//     }
+//
+// Note how the version in the path pattern changed from `v1` to `v2`.
+//
+// If the `root` field in the mixin is specified, it should be a
+// relative path under which inherited HTTP paths are placed. Example:
+//
+//     apis:
+//     - name: google.storage.v2.Storage
+//       mixins:
+//       - name: google.acl.v1.AccessControl
+//         root: acls
+//
+// This implies the following inherited HTTP annotation:
+//
+//     service Storage {
+//       // Get the underlying ACL object.
+//       rpc GetAcl(GetAclRequest) returns (Acl) {
+//         option (google.api.http).get = "/v2/acls/{resource=**}:getAcl";

+// In JSON format, the Timestamp type is encoded as a string in the
+// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+// where {year} is always expressed using four digits while {month}, {day},
+// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+// is required. A proto3 JSON serializer should always use UTC (as indicated by
+// "Z") when printing the Timestamp type and a proto3 JSON parser should be
+// able to accept both UTC and other timezones (as indicated by an offset).
+//
+// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+// 01:30 UTC on January 15, 2017.

+## Packages and input paths ##
+
+The protocol buffer language has a concept of "packages" which does not
+correspond well to the Go notion of packages. In generated Go code,
+each source `.proto` file is associated with a single Go package. The
+name and import path for this package is specified with the `go_package`
+proto option:
+
+	option go_package = "github.com/golang/protobuf/ptypes/any";
+
+The protocol buffer compiler will attempt to derive a package name and
+import path if a `go_package` option is not present, but it is
+best to always specify one explicitly.
+
+There is a one-to-one relationship between source `.proto` files and
+generated `.pb.go` files, but any number of `.pb.go` files may be
+contained in the same Go package.
+
+The output name of a generated file is produced by replacing the
+`.proto` suffix with `.pb.go` (e.g., `foo.proto` produces `foo.pb.go`).
+However, the output directory is selected in one of two ways.  Let
+us say we have `inputs/x.proto` with a `go_package` option of
+`github.com/golang/protobuf/p`. The corresponding output file may
+be:
+
+- Relative to the import path:
+
+```shell
+  protoc --go_out=. inputs/x.proto
+  # writes ./github.com/golang/protobuf/p/x.pb.go
+```
+
+  (This can work well with `--go_out=$GOPATH`.)

+- Relative to the input file:
+
+```shell
+protoc --go_out=paths=source_relative:. inputs/x.proto

+### Graceful Shutdown
+
+Go 1.8 introduced the ability to [gracefully shutdown](https://golang.org/doc/go1.8#http_shutdown) a `*http.Server`. Here's how to do that alongside `mux`:
+
+```go
+package main
+
+import (
+    "context"
+    "flag"
+    "log"
+    "net/http"
+    "os"
+    "os/signal"
+    "time"
+
+    "github.com/gorilla/mux"
+)
+
+func main() {
+    var wait time.Duration
+    flag.DurationVar(&wait, "graceful-timeout", time.Second * 15, "the duration for which the server gracefully wait for existing connections to finish - e.g. 15s or 1m")
+    flag.Parse()
+
+    r := mux.NewRouter()
+    // Add your routes as needed
+
+    srv := &http.Server{
+        Addr:         "0.0.0.0:8080",
+        // Good practice to set timeouts to avoid Slowloris attacks.
+        WriteTimeout: time.Second * 15,
+        ReadTimeout:  time.Second * 15,
+        IdleTimeout:  time.Second * 60,
+        Handler: r, // Pass our instance of gorilla/mux in.
+    }
+
+    // Run our server in a goroutine so that it doesn't block.
+    go func() {
+        if err := srv.ListenAndServe(); err != nil {
+            log.Println(err)
+        }
+    }()
+
+    c := make(chan os.Signal, 1)
+    // We'll accept graceful shutdowns when quit via SIGINT (Ctrl+C)
+    // SIGKILL, SIGQUIT or SIGTERM (Ctrl+/) will not be caught.
+    signal.Notify(c, os.Interrupt)
+
+    // Block until we receive our signal.
+    <-c
+
+    // Create a deadline to wait for.
+    ctx, cancel := context.WithTimeout(context.Background(), wait)
+    defer cancel()
+    // Doesn't block if no connections, but will otherwise wait
+    // until the timeout deadline.
+    srv.Shutdown(ctx)
+    // Optionally, you could run srv.Shutdown in a goroutine and block on
+    // <-ctx.Done() if your application should wait for other services
+    // to finalize based on context cancellation.
+    log.Println("shutting down")
+    os.Exit(0)
+}
+```
+
+### Middleware
+
+Mux supports the addition of middlewares to a [Router](https://godoc.org/github.com/gorilla/mux#Router), which are executed in the order they are added if a match is found, including its subrouters.
+Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or `ResponseWriter` hijacking.
+
+Mux middlewares are defined using the de facto standard type:
+
+```go
+type MiddlewareFunc func(http.Handler) http.Handler
+```
+
+Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc. This takes advantage of closures being able access variables from the context where they are created, while retaining the signature enforced by the receivers.
+
+A very basic middleware which logs the URI of the request being handled could be written as:
+
+```go
+func loggingMiddleware(next http.Handler) http.Handler {
+    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+        // Do stuff here
+        log.Println(r.RequestURI)
+        // Call the next handler, which can be another middleware in the chain, or the final handler.
+        next.ServeHTTP(w, r)
+    })
+}
+```
+
+Middlewares can be added to a router using `Router.Use()`:
+
+```go
+r := mux.NewRouter()
+r.HandleFunc("/", handler)
+r.Use(loggingMiddleware)
+```
+
+A more complex authentication middleware, which maps session token to users, could be written as:
+
+```go
+// Define our struct
+type authenticationMiddleware struct {
+	tokenUsers map[string]string
+}
+
+// Initialize it somewhere
+func (amw *authenticationMiddleware) Populate() {
+	amw.tokenUsers["00000000"] = "user0"
+	amw.tokenUsers["aaaaaaaa"] = "userA"
+	amw.tokenUsers["05f717e5"] = "randomUser"
+	amw.tokenUsers["deadbeef"] = "user0"
+}
+
+// Middleware function, which will be called for each request
+func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler {
+    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+        token := r.Header.Get("X-Session-Token")
+
+        if user, found := amw.tokenUsers[token]; found {
+        	// We found the token in our map
+        	log.Printf("Authenticated user %s\n", user)
+        	// Pass down the request to the next middleware (or final handler)
+        	next.ServeHTTP(w, r)
+        } else {
+        	// Write an error and stop the handler chain
+        	http.Error(w, "Forbidden", http.StatusForbidden)
+        }
+    })
+}
+```
+
+```go
+r := mux.NewRouter()
+r.HandleFunc("/", handler)
+
+amw := authenticationMiddleware{}
+amw.Populate()
+
+r.Use(amw.Middleware)
+```
+
+Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to. Middlewares _should_ write to `ResponseWriter` if they _are_ going to terminate the request, and they _should not_ write to `ResponseWriter` if they _are not_ going to terminate it.
+
+### Testing Handlers
+
+Testing handlers in a Go web application is straightforward, and _mux_ doesn't complicate this any further. Given two files: `endpoints.go` and `endpoints_test.go`, here's how we'd test an application using _mux_.
+
+First, our simple HTTP handler:
+
+```go
+// endpoints.go
+package main
+
+func HealthCheckHandler(w http.ResponseWriter, r *http.Request) {
+    // A very simple health check.
+    w.WriteHeader(http.StatusOK)
+    w.Header().Set("Content-Type", "application/json")
+
+    // In the future we could report back on the status of our DB, or our cache
+    // (e.g. Redis) by performing a simple PING, and include them in the response.
+    io.WriteString(w, `{"alive": true}`)
+}
+
+func main() {
+    r := mux.NewRouter()
+    r.HandleFunc("/health", HealthCheckHandler)
+
+    log.Fatal(http.ListenAndServe("localhost:8080", r))
+}
+```
+
+Our test code:
+
+```go
+// endpoints_test.go
+package main
+
+import (
+    "net/http"
+    "net/http/httptest"
+    "testing"
+)
+
+func TestHealthCheckHandler(t *testing.T) {
+    // Create a request to pass to our handler. We don't have any query parameters for now, so we'll
+    // pass 'nil' as the third parameter.
+    req, err := http.NewRequest("GET", "/health", nil)
+    if err != nil {
+        t.Fatal(err)
+    }
+
+    // We create a ResponseRecorder (which satisfies http.ResponseWriter) to record the response.
+    rr := httptest.NewRecorder()
+    handler := http.HandlerFunc(HealthCheckHandler)
+
+    // Our handlers satisfy http.Handler, so we can call their ServeHTTP method
+    // directly and pass in our Request and ResponseRecorder.
+    handler.ServeHTTP(rr, req)
+
+    // Check the status code is what we expect.
+    if status := rr.Code; status != http.StatusOK {
+        t.Errorf("handler returned wrong status code: got %v want %v",
+            status, http.StatusOK)
+    }
+
+    // Check the response body is what we expect.

+In the case that our routes have [variables](#examples), we can pass those in the request. We could write
+[table-driven tests](https://dave.cheney.net/2013/06/09/writing-table-driven-tests-in-go) to test multiple
+possible route variables as needed.
+
+```go
+// endpoints.go
+func main() {
+    r := mux.NewRouter()
+    // A route with a route variable:
+    r.HandleFunc("/metrics/{type}", MetricsHandler)
+
+    log.Fatal(http.ListenAndServe("localhost:8080", r))
+}
+```
+

+

+            t.Fatal(err)
+        }
+
+        rr := httptest.NewRecorder()
+	
+	// Need to create a router that we can pass the request through so that the vars will be added to the context
+	router := mux.NewRouter()

+        router.ServeHTTP(rr, req)
+
+        // In this case, our MetricsHandler returns a non-200 response
+        // for a route variable it doesn't know about.
+        if rr.Code == http.StatusOK && !tc.shouldPass {

+Mux supports the addition of middlewares to a Router, which are executed in the order they are added if a match is found, including its subrouters. Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or ResponseWriter hijacking.
+
+	type MiddlewareFunc func(http.Handler) http.Handler
+
+Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc (closures can access variables from the context where they are created).
+
+A very basic middleware which logs the URI of the request being handled could be written as:
+
+	func simpleMw(next http.Handler) http.Handler {
+		return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+			// Do stuff here
+			log.Println(r.RequestURI)
+			// Call the next handler, which can be another middleware in the chain, or the final handler.
+			next.ServeHTTP(w, r)
+		})
+	}
+
+Middlewares can be added to a router using `Router.Use()`:
+
+	r := mux.NewRouter()
+	r.HandleFunc("/", handler)
+	r.Use(simpleMw)
+
+A more complex authentication middleware, which maps session token to users, could be written as:
+
+	// Define our struct
+	type authenticationMiddleware struct {
+		tokenUsers map[string]string
+	}
+
+	// Initialize it somewhere
+	func (amw *authenticationMiddleware) Populate() {
+		amw.tokenUsers["00000000"] = "user0"
+		amw.tokenUsers["aaaaaaaa"] = "userA"
+		amw.tokenUsers["05f717e5"] = "randomUser"
+		amw.tokenUsers["deadbeef"] = "user0"
+	}
+
+	// Middleware function, which will be called for each request
+	func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler {
+		return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+			token := r.Header.Get("X-Session-Token")
+
+			if user, found := amw.tokenUsers[token]; found {
+				// We found the token in our map
+				log.Printf("Authenticated user %s\n", user)
+				next.ServeHTTP(w, r)
+			} else {
+				http.Error(w, "Forbidden", http.StatusForbidden)
+			}
+		})
+	}
+
+	r := mux.NewRouter()
+	r.HandleFunc("/", handler)
+
+	amw := authenticationMiddleware{}
+	amw.Populate()
+
+	r.Use(amw.Middleware)
+
+Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to.

+### Latest release
+
+[Release v0.3.6](https://github.com/imdario/mergo/releases/tag/v0.3.6).
 
 ### Important note
 
-Mergo is intended to assign **only** zero value fields on destination with source value. Since April 6th it works like this. Before it didn't work properly, causing some random overwrites. After some issues and PRs I found it didn't merge as I designed it. Thanks to [imdario/mergo#8](https://github.com/imdario/mergo/pull/8) overwriting functions were added and the wrong behavior was clearly detected.
+Please keep in mind that in [0.3.2](//github.com/imdario/mergo/releases/tag/0.3.2) Mergo changed `Merge()`and `Map()` signatures to support [transformers](#transformers). An optional/variadic argument has been added, so it won't break existing code.
 
 If you were using Mergo **before** April 6th 2015, please check your project works as intended after updating your local copy with ```go get -u github.com/imdario/mergo```. I apologize for any issue caused by its previous behavior and any future bug that Mergo could cause (I hope it won't!) in existing projects after the change (release 0.2.0).
 
+### Donations

+If Mergo is useful to you, consider buying me a coffee, a beer or making a monthly donation so I can keep building great free software. :heart_eyes:

 ## Usage
 
-You can only merge same-type structs with exported fields initialized as zero value of their type and same-types maps. Mergo won't merge unexported (private) fields but will do recursively any exported one. Also maps will be merged recursively except for structs inside maps (because they are not addressable using Go reflection).
+You can only merge same-type structs with exported fields initialized as zero value of their type and same-types maps. Mergo won't merge unexported (private) fields but will do recursively any exported one. It won't merge empty structs value as [they are not considered zero values](https://golang.org/ref/spec#The_zero_value) either. Also maps will be merged recursively except for structs inside maps (because they are not addressable using Go reflection).
+
+```go
+if err := mergo.Merge(&dst, src); err != nil {
+    // ...
+}
+```
+
+Also, you can merge overwriting values using the transformer `WithOverride`.
 
-    if err := mergo.Merge(&dst, src); err != nil {
-        // ...
-    }
+```go
+if err := mergo.Merge(&dst, src, mergo.WithOverride); err != nil {
+    // ...
+}
+```
 
-Additionally, you can map a map[string]interface{} to a struct (and otherwise, from struct to map), following the same restrictions as in Merge(). Keys are capitalized to find each corresponding exported field.

+### Transformers
+
+Transformers allow to merge specific types differently than in the default behavior. In other words, now you can customize how some types are merged. For example, `time.Time` is a struct; it doesn't have zero value but IsZero can return true because it has fields with zero value. How can we merge a non-zero `time.Time`?

 `containers-golang` is a set of Go libraries used by container runtimes to generate and load seccomp mappings into the kernel.
 
-seccomp (short for secure computing mode) is a computer security facility in the Linux kernel. It was merged into the Linux kernel mainline in kernel version 2.6.12, which was released on March 8, 2005.[1] seccomp allows a process to make a one-way transition into a "secure" state where it cannot make any system calls except exit(), sigreturn(), read() and write() to already-open file descriptors. Should it attempt any other system calls, the kernel will terminate the process with SIGKILL or SIGSYS[2][3]. In this sense, it does not virtualize the system's resources but isolates the process from them entirely.

-## Dependencies
+seccomp (short for secure computing mode) is a BPF based syscall filter language and present a more conventional function-call based filtering interface that should be familiar to, and easily adopted by, application developers.
 
 ## Building
+   make - Generates default.json file, which containes the whitelisted syscalls that can be used by container runtime engines like [CRI-O][cri-o], [Buildah][buildah], [Podman][podman] and [Docker][docker], and container runtimes like OCI [Runc][runc] to controll the syscalls available to containers.
 
 ### Supported build tags

+## Loading local schemas
+
+By default `file` and `http(s)` references to external schemas are loaded automatically via the file system or via http(s). An external schema can also be loaded using a `SchemaLoader`.
+
+```go
+	sl := gojsonschema.NewSchemaLoader()
+	loader1 := gojsonschema.NewStringLoader(`{ "type" : "string" }`)
+	err := sl.AddSchema("http://some_host.com/string.json", loader1)
+```
+
+Alternatively if your schema already has an `$id` you can use the `AddSchemas` function
+```go
+	loader2 := gojsonschema.NewStringLoader(`{
+			"$id" : "http://some_host.com/maxlength.json",
+			"maxLength" : 5
+		}`)
+	err = sl.AddSchemas(loader2)
+```
+
+The main schema should be passed to the `Compile` function. This main schema can then directly reference the added schemas without needing to download them.
+```go
+	loader3 := gojsonschema.NewStringLoader(`{
+		"$id" : "http://some_host.com/main.json",
+		"allOf" : [
+			{ "$ref" : "http://some_host.com/string.json" },
+			{ "$ref" : "http://some_host.com/maxlength.json" }
+		]
+	}`)
+
+	schema, err := sl.Compile(loader3)
+
+	documentLoader := gojsonschema.NewStringLoader(`"hello world"`)
+
+	result, err := schema.Validate(documentLoader)
+```
+
+It's also possible to pass a `ReferenceLoader` to the `Compile` function that references a loaded schema.
+
+```go
+err = sl.AddSchemas(loader3)
+schema, err := sl.Compile(gojsonschema.NewReferenceLoader("http://some_host.com/main.json"))
+``` 
+
+Schemas added by `AddSchema` and `AddSchemas` are only validated when the entire schema is compiled, unless meta-schema validation is used.
+
+## Using a specific draft
+By default `gojsonschema` will try to detect the draft of a schema by using the `$schema` keyword and parse it in a strict draft-04, draft-06 or draft-07 mode. If `$schema` is missing, or the draft version is not explicitely set, a hybrid mode is used which merges together functionality of all drafts into one mode.
+
+Autodectection can be turned off with the `AutoDetect` property. Specific draft versions can be specified with the `Draft` property.
+
+```go
+sl := gojsonschema.NewSchemaLoader()
+sl.Draft = gojsonschema.Draft7
+sl.AutoDetect = false
+```
+
+If autodetection is on (default), a draft-07 schema can savely reference draft-04 schemas and vice-versa, as long as `$schema` is specified in all schemas.
+
+## Meta-schema validation
+Schemas that are added using the `AddSchema`, `AddSchemas` and `Compile` can be validated against their meta-schema by setting the `Validate` property.
+
+The following example will produce an error as `multipleOf` must be a number. If `Validate` is off (default), this error is only returned at the `Compile` step. 
+
+```go
+sl := gojsonschema.NewSchemaLoader()
+sl.Validate = true
+err := sl.AddSchemas(gojsonschema.NewStringLoader(`{
+     $id" : "http://some_host.com/invalid.json",
+    "$schema": "http://json-schema.org/draft-07/schema#",
+    "multipleOf" : true
+}`))
+ ```
+``` 
+ ```
+
+Errors returned by meta-schema validation are more readable and contain more information, which helps significantly if you are developing a schema.
+
+Meta-schema validation also works with a custom `$schema`. In case `$schema` is missing, or `AutoDetect` is set to `false`, the meta-schema of the used draft is used.

 ## Formats
 JSON Schema allows for optional "format" property to validate instances against well-known formats. gojsonschema ships with all of the formats defined in the spec that you can use like this:
+
 ````json
 {"type": "string", "format": "email"}
 ````
-Available formats: date-time, hostname, email, ipv4, ipv6, uri, uri-reference.
+
+Not all formats defined in draft-07 are available. Implemented formats are:
+
+* `date`
+* `time`
+* `date-time`
+* `hostname`. Subdomains that start with a number are also supported, but this means that it doesn't strictly follow [RFC1034](http://tools.ietf.org/html/rfc1034#section-3.5) and has the implication that ipv4 addresses are also recognized as valid hostnames.
+* `email`. Go's email parser deviates slightly from [RFC5322](https://tools.ietf.org/html/rfc5322). Includes unicode support.
+* `idn-email`. Same caveat as `email`.
+* `ipv4`
+* `ipv6`
+* `uri`. Includes unicode support.
+* `uri-reference`. Includes unicode support.
+* `iri`
+* `iri-reference`
+* `uri-template`
+* `uuid`
+* `regex`. Go uses the [RE2](https://github.com/google/re2/wiki/Syntax) engine and is not [ECMA262](http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-262.pdf) compatible.
+* `json-pointer`
+* `relative-json-pointer`
+
+`email`, `uri` and `uri-reference` use the same validation code as their unicode counterparts `idn-email`, `iri` and `iri-reference`. If you rely on unicode support you should use the specific 
+unicode enabled formats for the sake of interoperability as other implementations might not support unicode in the regular formats.
+
+The validation code for `uri`, `idn-email` and their relatives use mostly standard library code. Go 1.5 and 1.6 contain some minor bugs with handling URIs and unicode. You are encouraged to use Go 1.7+ if you rely on these formats.
 
 For repetitive or more complex formats, you can create custom format checkers and add them to gojsonschema like this:
 
@@ -285,7 +400,63 @@ func (f ValidUserIdFormatChecker) IsFormat(input interface{}) bool {
 gojsonschema.FormatCheckers.Add("ValidUserId", ValidUserIdFormatChecker{})
 ````
 
+Formats can also be removed, for example if you want to override one of the formats that is defined by default.
+
+```go
+gojsonschema.FormatCheckers.Remove("hostname")
+```
+
+
+## Additional custom validation
+After the validation has run and you have the results, you may add additional
+errors using `Result.AddError`. This is useful to maintain the same format within the resultset instead
+of having to add special exceptions for your own errors. Below is an example.
+
+```go
+type AnswerInvalidError struct {
+    gojsonschema.ResultErrorFields
+}
+
+func newAnswerInvalidError(context *gojsonschema.JsonContext, value interface{}, details gojsonschema.ErrorDetails) *AnswerInvalidError {
+    err := AnswerInvalidError{}
+    err.SetContext(context)
+    err.SetType("custom_invalid_error")
+    // it is important to use SetDescriptionFormat() as this is used to call SetDescription() after it has been parsed
+    // using the description of err will be overridden by this.
+    err.SetDescriptionFormat("Answer to the Ultimate Question of Life, the Universe, and Everything is {{.answer}}")
+    err.SetValue(value)
+    err.SetDetails(details)
+
+    return &err
+}
+
+func main() {
+    // ...
+    schema, err := gojsonschema.NewSchema(schemaLoader)
+    result, err := gojsonschema.Validate(schemaLoader, documentLoader)
+
+    if true { // some validation
+        jsonContext := gojsonschema.NewJsonContext("question", nil)
+        errDetail := gojsonschema.ErrorDetails{
+            "answer": 42,
+        }
+        result.AddError(
+            newAnswerInvalidError(
+                gojsonschema.NewJsonContext("answer", jsonContext),
+                52,
+                errDetail,
+            ),
+            errDetail,
+        )
+    }
+
+    return result, err
+
+}
+```
 
+This is especially useful if you want to add validation beyond what the
+json schema drafts can provide such business specific logic.
