+# Contributing to Buildah
+
+We'd love to have you join the community! Below summarizes the processes
+that we follow.
+
+## Topics
+
+* [Reporting Issues](#reporting-issues)
+* [Submitting Pull Requests](#submitting-pull-requests)
+* [Sign your PRs](#sign-your-prs)
+* [Communications](#communications)
+* [Becoming a Maintainer](#becoming-a-maintainer)
+
+## Reporting Issues
+
+Before reporting an issue, check our backlog of
+[open issues](https://github.com/containers/buildah/issues)
+to see if someone else has already reported it. If so, feel free to add
+your scenario, or additional information, to the discussion. Or simply
+"subscribe" to it to be notified when it is updated.
+
+If you find a new issue with the project we'd love to hear about it! The most
+important aspect of a bug report is that it includes enough information for
+us to reproduce it. So, please include as much detail as possible and try
+to remove the extra stuff that doesn't really relate to the issue itself.
+The easier it is for us to reproduce it, the faster it'll be fixed!
+
+Please don't include any private/sensitive information in your issue!
+
+## Submitting Pull Requests
+
+No Pull Request (PR) is too small! Typos, additional comments in the code,
+new testcases, bug fixes, new features, more documentation, ... it's all
+welcome!
+
+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. But, squashing down to just one commit is ok
+too since in the end the entire PR will be reviewed anyway. When in doubt,
+squash.
+
+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.
+
+<!--
+All PRs require at least two LGTMs (Looks Good To Me) from maintainers.
+-->
+
+### Sign your PRs
+
+The sign-off is a line at the end of the explanation for the patch. Your
+signature certifies that you wrote the patch or otherwise have the right to pass
+it on as an open-source patch. The rules are simple: if you can certify
+the below (from [developercertificate.org](http://developercertificate.org/)):
+
+```
+Developer Certificate of Origin
+Version 1.1
+
+Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
+660 York Street, Suite 102,
+San Francisco, CA 94110 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+Developer's Certificate of Origin 1.1
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the open source license
+    indicated in the file; or
+
+(b) The contribution is based upon previous work that, to the best
+    of my knowledge, is covered under an appropriate open source
+    license and I have the right under that license to submit that
+    work with modifications, whether created in whole or in part
+    by me, under the same open source license (unless I am
+    permitted to submit under a different license), as indicated
+    in the file; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a), (b) or (c) and I have not modified
+    it.
+
+(d) I understand and agree that this project and the contribution
+    are public and that a record of the contribution (including all
+    personal information I submit with it, including my sign-off) is
+    maintained indefinitely and may be redistributed consistent with
+    this project or the open source license(s) involved.
+```
+
+Then you just add a line to every git commit message:
+
+    Signed-off-by: Joe Smith <joe.smith@email.com>
+
+Use your real name (sorry, no pseudonyms or anonymous contributions.)
+
+If you set your `user.name` and `user.email` git configs, you can sign your
+commit automatically with `git commit -s`.
+
+## Communications
+
+For general questions, or discussions, please use the
+IRC group on `irc.freenode.net` called `buildah`
+that has been setup.
+
+For discussions around issues/bugs and features, you can use the github
+[issues](https://github.com/containers/buildah/issues)
+and
+[PRs](https://github.com/containers/buildah/pulls)
+tracking system.
+
+## Becoming a Maintainer
+
+To become a maintainer you must first be nominated by an existing maintainer.
+If a majority (>50%) of maintainers agree then the proposal is adopted and
+you will be added to the list.
+
+Removing a maintainer requires at least 75% of the remaining maintainers
+approval, or if the person requests to be removed then it is automatic.
+Normally, a maintainer will only be removed if they are considered to be
+inactive for a long period of time or are viewed as disruptive to the community.
+
+The current list of maintainers can be found in the
+[MAINTAINERS](MAINTAINERS) file.

+# Development Plan
+
+## Development goals for Buildah
+
+ *  Integration into Kubernetes and potentially other tools.  The biggest requirement for this is to be able run Buildah within a standard linux container without SYS_ADMIN privileges.  This would allow Buildah to run non-privileged containers inside of Kubernetes, so you could distribute your container workloads.
+
+ * Integration with User Namespace, Podman has this already and the goal is to get `buildah bud` and `buildah run` to be able to run its containers in a usernamespace to give the builder better security isolation from the host.
+
+ * Buildah `buildah bud` command's goal is to have feature parity with other OCI image and container build systems.
+
+ * Addressing issues from the community as reported in the [Issues](https://github.com/containers/buildah/issues) page.

+sudo add-apt-repository -y ppa:projectatomic/ppa
+sudo apt-get update -qq
+sudo apt-get -qq -y install buildah
+```
+
+# Building from scratch
+
+## System Requirements
+
+### Kernel Version Requirements
+To run Buildah on Red Hat Enterprise Linux or CentOS, version 7.4 or higher is required.
+On other Linux distributions Buildah requires a kernel version of 4.0 or
+higher in order to support the OverlayFS filesystem.  The kernel version can be checked
+with the 'uname -a' command.
+
+### runc Requirement
+
+Buildah uses `runc` to run commands when `buildah run` is used, or when `buildah build-using-dockerfile`
+encounters a `RUN` instruction, so you'll also need to build and install a compatible version of
+[runc](https://github.com/opencontainers/runc) for Buildah to call for those cases.  If Buildah is installed
+via a package manager such as yum, dnf or apt-get, runc will be installed as part of that process.
+
+### CNI Requirement
+
+When Buildah uses `runc` to run commands, it defaults to running those commands
+in the host's network namespace.  If the command is being run in a separate
+user namespace, though, for example when ID mapping is used, then the command
+will also be run in a separate network namespace.
+
+A newly-created network namespace starts with no network interfaces, so
+commands which are run in that namespace are effectively disconnected from the
+network unless additional setup is done.  Buildah relies on the CNI
+[library](https://github.com/containernetworking/cni) and
+[plugins](https://github.com/containernetworking/plugins) to set up interfaces
+and routing for network namespaces.
+
+If Buildah is installed via a package manager such as yum, dnf or apt-get, a
+package containing CNI plugins may be available (in Fedora, the package is
+named `containernetworking-cni`).  If not, they will need to be installed,
+for example using:
+```
+  git clone https://github.com/containernetworking/plugins
+  ( cd ./plugins; ./build.sh )
+  mkdir -p /opt/cni/bin
+  install -v ./plugins/bin/* /opt/cni/bin
+```
+
+The CNI library needs to be configured so that it will know which plugins to
+call to set up namespaces.  Usually, this configuration takes the form of one
+or more configuration files in the `/etc/cni/net.d` directory.  A set of example
+configuration files is included in the
+[`docs/cni-examples`](https://github.com/containers/buildah/tree/master/docs/cni-examples)
+directory of this source tree.
+
+## Package Installation
+
+Buildah is available on several software repositories and can be installed via a package manager such
+as yum, dnf or apt-get on a number of Linux distributions.
+
+## Installation from GitHub
+
+Prior to installing Buildah, install the following packages on your Linux distro:
+* make
+* golang (Requires version 1.10 or higher.)
+* bats
+* btrfs-progs-devel
+* bzip2
+* device-mapper-devel
+* git
+* go-md2man
+* gpgme-devel
+* glib2-devel
+* libassuan-devel
+* libseccomp-devel
+* ostree-devel
+* runc (Requires version 1.0 RC4 or higher.)
+* containers-common
+
+### Fedora
+
+In Fedora, you can use this command:
+
+```
+ dnf -y install \
+    make \
+    golang \
+    bats \
+    btrfs-progs-devel \
+    device-mapper-devel \
+    glib2-devel \
+    gpgme-devel \
+    libassuan-devel \
+    libseccomp-devel \
+    ostree-devel \
+    git \
+    bzip2 \
+    go-md2man \
+    runc \
+    containers-common
+```
+
+Then to install Buildah on Fedora follow the steps in this example:
+
+```
+  mkdir ~/buildah
+  cd ~/buildah
+  export GOPATH=`pwd`
+  git clone https://github.com/containers/buildah ./src/github.com/containers/buildah
+  cd ./src/github.com/containers/buildah
+  make
+  sudo make install
+  buildah --help
+```
+
+### RHEL, CentOS
+
+In RHEL and CentOS 7, ensure that you are subscribed to the `rhel-7-server-rpms`,
+`rhel-7-server-extras-rpms`, `rhel-7-server-optional-rpms` and `EPEL` repositories, then
+run this command:
+
+```
+ yum -y install \
+    make \
+    golang \
+    bats \
+    btrfs-progs-devel \
+    device-mapper-devel \
+    glib2-devel \
+    gpgme-devel \
+    libassuan-devel \
+    libseccomp-devel \
+    ostree-devel \
+    git \
+    bzip2 \
+    go-md2man \
+    runc \
+    skopeo-containers
+```
+
+The build steps for Buildah on RHEL or CentOS are the same as for Fedora, above.
+
+*NOTE:* Buildah on RHEL or CentOS version 7.* is not supported running as non-root due to
+these systems not having newuidmap or newgidmap installed.  It is possible to pull
+the shadow-utils source RPM from Fedora 29 and build and install from that in order to
+run Buildah as non-root on these systems.
+
+### openSUSE
+
+On openSUSE Tumbleweed, install go via `zypper in go`, then run this command:
+
+```
+ zypper in make \
+    git \
+    golang \
+    runc \
+    bzip2 \
+    libgpgme-devel \
+    libseccomp-devel \
+    device-mapper-devel \
+    libbtrfs-devel \
+    go-md2man
+```
+
+The build steps for Buildah on SUSE / openSUSE are the same as for Fedora, above.
+
+
+### Ubuntu
+
+In Ubuntu zesty and xenial, you can use these commands:
+
+```
+  apt-get -y install software-properties-common
+  add-apt-repository -y ppa:alexlarsson/flatpak
+  add-apt-repository -y ppa:gophers/archive
+  apt-add-repository -y ppa:projectatomic/ppa
+  apt-get -y -qq update
+  apt-get -y install bats btrfs-tools git libapparmor-dev libdevmapper-dev libglib2.0-dev libgpgme11-dev libostree-dev libseccomp-dev libselinux1-dev skopeo-containers go-md2man
+  apt-get -y install golang-1.10
+```
+Then to install Buildah on Ubuntu follow the steps in this example:
+
+```
+  mkdir ~/buildah
+  cd ~/buildah
+  export GOPATH=`pwd`
+  git clone https://github.com/containers/buildah ./src/github.com/containers/buildah
+  cd ./src/github.com/containers/buildah
+  PATH=/usr/lib/go-1.10/bin:$PATH make runc all SECURITYTAGS="apparmor seccomp"
+  sudo make install install.runc
+  buildah --help
+```
+
+### Debian
+
+To install the required dependencies, you can use those commands, tested under Debian GNU/Linux amd64 9.3 (stretch):
+
+```
+gpg --recv-keys 0x018BA5AD9DF57A4448F0E6CF8BECF1637AD8C79D
+gpg --export 0x018BA5AD9DF57A4448F0E6CF8BECF1637AD8C79D >> /usr/share/keyrings/projectatomic-ppa.gpg
+echo 'deb [signed-by=/usr/share/keyrings/projectatomic-ppa.gpg] http://ppa.launchpad.net/projectatomic/ppa/ubuntu zesty main' > /etc/apt/sources.list.d/projectatomic-ppa.list
+apt update
+apt -y install -t stretch-backports libostree-dev golang
+apt -y install bats btrfs-tools git libapparmor-dev libdevmapper-dev libglib2.0-dev libgpgme11-dev libseccomp-dev libselinux1-dev skopeo-containers go-md2man
+```
+
+The build steps on Debian are otherwise the same as Ubuntu, above.
+
+## Vendoring - Dependency Management
+
+This project is using [vndr](https://github.com/LK4D4/vndr) for managing dependencies, which is a tedious and error-prone task. Doing it manually is likely to cause inconsistencies between the `./vendor` directory (i.e., the downloaded dependencies), the source code that imports those dependencies and the `vendor.conf` configuration file that describes which packages in which version (e.g., a release or git commit) are a dependency.
+
+To ease updating dependencies, we provide the `make vendor` target, which fetches all dependencies mentioned in `vendor.conf`.  `make vendor` whitelists certain packages to prevent the `vndr` tool from removing packages that the test suite (see `./test`) imports.
+
+The CI of this project makes sure that each pull request leaves a clean vendor state behind by first running the aforementioned `make vendor` followed by running `./hack/tree_status.sh` which checks if any file in the git tree has changed.
+
+### Vendor Troubleshooting
+
+If the CI is complaining about a pull request leaving behind an unclean state, it is very likely right about it. Make sure to run `make vendor` and add all the changes to the commit. Also make sure that your local git tree does not include files not under version control that may reference other go packages. If some dependencies are removed but they should not, for instance, because the CI is needing them, then whitelist those dependencies in the `make vendor` target of the Makefile.  Whitelisting a package will instruct `vndr` to not remove if during its cleanup phase.
+sd
+
+## Configuration files
+
+The following configuration files are required in order for Buildah to run appropriately.  The
+majority of these files are commonly contained in the `containers-common` package.
+
+### [registries.conf](https://github.com/containers/buildah/blob/master/docs/samples/registries.conf)
+
+#### Man Page: [registries.conf.5](https://github.com/containers/image/blob/master/docs/containers-registries.conf.5.md)
+
+`/etc/containers/registries.conf`
+
+registries.conf is the configuration file which specifies which container registries should be consulted when completing image names which do not include a registry or domain portion.
+
+#### Example from the Fedora `containers-common` package
+
+```
+cat /etc/containers/registries.conf
+# This is a system-wide configuration file used to
+# keep track of registries for various container backends.
+# It adheres to TOML format and does not support recursive
+# lists of registries.
+
+# The default location for this configuration file is /etc/containers/registries.conf.
+
+# The only valid categories are: 'registries.search', 'registries.insecure',
+# and 'registries.block'.
+
+[registries.search]
+registries = ['docker.io', 'registry.fedoraproject.org', 'quay.io', 'registry.access.redhat.com', 'registry.centos.org']
+
+# If you need to access insecure registries, add the registry's fully-qualified name.
+# An insecure registry is one that does not have a valid SSL certificate or only does HTTP.
+[registries.insecure]
+registries = []
+
+
+# If you need to block pull access from a registry, uncomment the section below
+# and add the registries fully-qualified name.
+#
+# Docker only
+[registries.block]
+registries = []
+```
+
+### [mounts.conf](https://src.fedoraproject.org/rpms/skopeo/blob/master/f/mounts.conf)
+
+`/usr/share/containers/mounts.conf` and optionally `/etc/containers/mounts.conf`
+
+The mounts.conf files specify volume mount directories that are automatically mounted inside containers when executing the `buildah run` or `buildah build-using-dockerfile` commands.  Container process can then use this content.  The volume mount content does not get committed to the final image.  This file is usually provided by the containers-common package.
+
+Usually these directories are used for passing secrets or credentials required by the package software to access remote package repositories.
+
+For example, a mounts.conf with the line "`/usr/share/rhel/secrets:/run/secrets`", the content of `/usr/share/rhel/secrets` directory is mounted on `/run/secrets` inside the container.  This mountpoint allows Red Hat Enterprise Linux subscriptions from the host to be used within the container.
+
+Note this is not a volume mount. The content of the volumes is copied into container storage, not bind mounted directly from the host.
+
+#### Example from the Fedora `containers-common` package:
+
+```
+cat /usr/share/containers/mounts.conf
+/usr/share/rhel/secrets:/run/secrets
+```
+
+### [seccomp.json](https://src.fedoraproject.org/rpms/skopeo/blob/master/f/seccomp.json)
+
+`/usr/share/containers/seccomp.json`
+
+seccomp.json contains the whitelist of seccomp rules to be allowed inside of
+containers.  This file is usually provided by the containers-common package.
+
+The link above takes you to the seccomp.json
+
+### [policy.json](https://github.com/containers/skopeo/blob/master/default-policy.json)
+
+`/etc/containers/policy.json`
+
+#### Man Page: [policy.json.5](https://github.com/containers/image/blob/master/docs/policy.json.md)
+
+
+#### Example from the Fedora `containers-common` package:
+
+```
+cat /etc/containers/policy.json
+{
+    "default": [
+	{
+	    "type": "insecureAcceptAnything"
+	}
+    ],
+    "transports":
+	{
+	    "docker-daemon":
+		{
+		    "": [{"type":"insecureAcceptAnything"}]
+		}
+	}
+}
+```

+# Troubleshooting
+
+## A list of common issues and solutions for Buildah
+
+---
+### 1) No such image
+
+When doing a `buildah pull` or `buildah bud` command and a "common" image can not be pulled,
+it is likely that the `/etc/containers/registries.conf` file is either not installed or possibly
+misconfigured.  This issue might also indicate that other required files as listed in the
+[Configuration Files](https://github.com/containers/buildah/blob/master/install.md#configuration-files)
+section of the Installation Instructions are also not installed.
+
+#### Symptom
+```console
+$ sudo buildah bud -f Dockerfile .
+STEP 1: FROM alpine
+error creating build container: 2 errors occurred:
+
+* Error determining manifest MIME type for docker://localhost/alpine:latest: pinging docker registry returned: Get https://localhost/v2/: dial tcp [::1]:443: connect: connection refused
+* Error determining manifest MIME type for docker://registry.access.redhat.com/alpine:latest: Error reading manifest latest in registry.access.redhat.com/alpine: unknown: Not Found
+error building: error creating build container: no such image "alpine" in registry: image not known
+```
+
+#### Solution
+
+  * Verify that the `/etc/containers/registries.conf` file exists.  If not, verify that the containers-common package is installed.
+  * Verify that the entries in the `[registries.search]` section of the /etc/containers/registries file are valid and reachable.
+  * Verify that the image you requested is either fully qualified, or that it exists on one of your search registries.
+  * Verify that the image is public or that you have logged in to at least one search registry which contains the private image.
+  * Verify that the other required [Configuration Files](https://github.com/containers/buildah/blob/master/install.md#configuration-files) are installed.
+
+---
+### 2) http: server gave HTTP response to HTTPS client
+
+When doing a Buildah command such as `bud`, `commit`, `from`, or `push` to a registry,
+tls verification is turned on by default.  If authentication is not used with
+those commands, this error can occur.
+
+#### Symptom
+```console
+# buildah push alpine docker://localhost:5000/myalpine:latest
+Getting image source signatures
+Get https://localhost:5000/v2/: http: server gave HTTP response to HTTPS client
+```
+
+#### Solution
+
+By default tls verification is turned on when communicating to registries from
+Buildah.  If the registry does not require authentication the Buildah commands
+such as `bud`, `commit`, `from` and `pull` will fail unless tls verification is turned
+off using the `--tls-verify` option.  **NOTE:** It is not at all recommended to
+communicate with a registry and not use tls verification.
+
+  * Turn off tls verification by passing false to the tls-verification option.
+  * I.e. `buildah push --tls-verify=false alpine docker://localhost:5000/myalpine:latest`
+
+---
+### 3) `buildah run` command fails with pipe or output redirection
+
+When doing a `buildah run` command while using a pipe ('|') or output redirection ('>>'),
+the command will fail, often times with a `command not found` type of error.
+
+#### Symptom
+When executing a `buildah run` command with a pipe or output redirection such as the
+following commands:
+
+```console
+# buildah run $whalecontainer /usr/games/fortune -a | cowsay
+# buildah run $newcontainer echo "daemon off;" >> /etc/nginx/nginx.conf
+# buildah run $newcontainer echo "nginx on Fedora" > /usr/share/nginx/html/index.html
+```
+the `buildah run` command will not complete and an error will be raised.
+
+#### Solution
+There are two solutions to this problem.  The
+[`podman run`](https://github.com/containers/libpod/blob/master/docs/podman-run.1.md)
+command can be used in place of `buildah run`.  To still use `buildah run`, surround
+the command with single quotes and use `bash -c`.  The previous examples would be
+changed to:
+
+```console
+# buildah run bash -c '$whalecontainer /usr/games/fortune -a | cowsay'
+# buildah run bash -c '$newcontainer echo "daemon off;" >> /etc/nginx/nginx.conf'
+# buildah run bash -c '$newcontainer echo "nginx on Fedora" > /usr/share/nginx/html/index.html'
+```
+
+---
+### 4) `buildah push alpine oci:~/myalpine:latest` fails with lstat error
+
+When doing a `buildah push` command and the target image has a tilde (`~`) character
+in it, an lstat error will be raised stating there is no such file or directory.
+This is expected behavior for shell expansion of the tilde character as it is only
+expanded at the start of a word.  This behavior is documented
+[here](https://www.gnu.org/software/libc/manual/html_node/Tilde-Expansion.html).
+
+#### Symptom
+```console
+$ sudo pull alpine
+$ sudo buildah push alpine oci:~/myalpine:latest
+lstat /home/myusername/~: no such file or directory
+```
+
+#### Solution
+
+  * Replace `~` with `$HOME` or the fully specified directory `/home/myusername`.
+    * `$ sudo buildah push alpine oci:${HOME}/myalpine:latest`

-[![GoDoc](https://godoc.org/github.com/containers/image?status.svg)](https://godoc.org/github.com/containers/image) [![Build Status](https://travis-ci.org/containers/image.svg?branch=master)](https://travis-ci.org/containers/image)
-=
-
-`image` is a set of Go libraries aimed at working in various way with
-containers' images and container image registries.
-
-The containers/image library allows application to pull and push images from
-container image registries, like the upstream docker registry. It also
-implements "simple image signing".
-
-The containers/image library also allows you to inspect a repository on a
-container registry without pulling down the image. This means it fetches the
-repository's manifest and it is able to show you a `docker inspect`-like json
-output about a whole repository or a tag. This library, in contrast to `docker
-inspect`, helps you gather useful information about a repository or a tag
-without requiring you to run `docker pull`.
-
-The containers/image library also allows you to translate from one image format
-to another, for example docker container images to OCI images. It also allows
-you to copy container images between various registries, possibly converting
-them as necessary, and to sign and verify images.
-
-## Command-line usage
-
-The containers/image project is only a library with no user interface;
-you can either incorporate it into your Go programs, or use the `skopeo` tool:
-
-The [skopeo](https://github.com/containers/skopeo) tool uses the
-containers/image library and takes advantage of many of its features,
-e.g. `skopeo copy` exposes the `containers/image/copy.Image` functionality.
-
-## Dependencies
-
-This library does not ship a committed version of its dependencies in a `vendor`
-subdirectory.  This is so you can make well-informed decisions about which
-libraries you should use with this package in your own projects, and because
-types defined in the `vendor` directory would be impossible to use from your projects.
-
-What this project tests against dependencies-wise is located
-[in vendor.conf](https://github.com/containers/image/blob/master/vendor.conf).
-
-## Building
-
-If you want to see what the library can do, or an example of how it is called,
-consider starting with the [skopeo](https://github.com/containers/skopeo) tool
-instead.
-
-To integrate this library into your project, put it into `$GOPATH` or use
-your preferred vendoring tool to include a copy in your project.
-Ensure that the dependencies documented [in vendor.conf](https://github.com/containers/image/blob/master/vendor.conf)
-are also available
-(using those exact versions or different versions of your choosing).
-
-This library, by default, also depends on the GpgME and libostree C libraries. Either install them:
-```sh
-Fedora$ dnf install gpgme-devel libassuan-devel ostree-devel
-macOS$ brew install gpgme
-```
-or use the build tags described below to avoid the dependencies (e.g. using `go build -tags …`)
-
-### Supported build tags
-
-- `containers_image_openpgp`: Use a Golang-only OpenPGP implementation for signature verification instead of the default cgo/gpgme-based implementation;
-the primary downside is that creating new signatures with the Golang-only implementation is not supported.
-- `containers_image_ostree_stub`: Instead of importing `ostree:` transport in `github.com/containers/image/transports/alltransports`, use a stub which reports that the transport is not supported. This allows building the library without requiring the `libostree` development libraries. The `github.com/containers/image/ostree` package is completely disabled
-and impossible to import when this build tag is in use.
-
-## [Contributing](CONTRIBUTING.md)
-
-Information about contributing to this project.
-
-When developing this library, please use `make` (or `make … BUILDTAGS=…`) to take advantage of the tests and validation.

+# Contributing to Containers/Storage 
+
+We'd love to have you join the community! Below summarizes the processes
+that we follow.
+
+## Topics
+
+* [Reporting Issues](#reporting-issues)
+* [Submitting Pull Requests](#submitting-pull-requests)
+* [Communications](#communications)
+<!--
+* [Becoming a Maintainer](#becoming-a-maintainer)
+-->
+
+## Reporting Issues
+
+Before reporting an issue, check our backlog of 
+[open issues](https://github.com/containers/storage/issues)
+to see if someone else has already reported it. If so, feel free to add
+your scenario, or additional information, to the discussion. Or simply 
+"subscribe" to it to be notified when it is updated.
+
+If you find a new issue with the project we'd love to hear about it! The most
+important aspect of a bug report is that it includes enough information for
+us to reproduce it. So, please include as much detail as possible and try
+to remove the extra stuff that doesn't really relate to the issue itself.
+The easier it is for us to reproduce it, the faster it'll be fixed!
+
+Please don't include any private/sensitive information in your issue!
+
+## Submitting Pull Requests
+
+No Pull Request (PR) is too small! Typos, additional comments in the code,
+new testcases, bug fixes, new features, more documentation, ... it's all 
+welcome!
+
+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. But, squashing down to just one commit is ok
+too since in the end the entire PR will be reviewed anyway. When in doubt, 
+squash.
+
+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.
+
+<!--
+All PRs require at least two LGTMs (Looks Good To Me) from maintainers.
+-->
+
+### Sign your PRs
+
+The sign-off is a line at the end of the explanation for the patch. Your
+signature certifies that you wrote the patch or otherwise have the right to pass
+it on as an open-source patch. The rules are simple: if you can certify
+the below (from [developercertificate.org](http://developercertificate.org/)):
+
+```
+Developer Certificate of Origin
+Version 1.1
+
+Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
+660 York Street, Suite 102,
+San Francisco, CA 94110 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+Developer's Certificate of Origin 1.1
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the open source license
+    indicated in the file; or
+
+(b) The contribution is based upon previous work that, to the best
+    of my knowledge, is covered under an appropriate open source
+    license and I have the right under that license to submit that
+    work with modifications, whether created in whole or in part
+    by me, under the same open source license (unless I am
+    permitted to submit under a different license), as indicated
+    in the file; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a), (b) or (c) and I have not modified
+    it.
+
+(d) I understand and agree that this project and the contribution
+    are public and that a record of the contribution (including all
+    personal information I submit with it, including my sign-off) is
+    maintained indefinitely and may be redistributed consistent with
+    this project or the open source license(s) involved.
+```
+
+Then you just add a line to every git commit message:
+
+    Signed-off-by: Joe Smith <joe.smith@email.com>
+
+Use your real name (sorry, no pseudonyms or anonymous contributions.)
+
+If you set your `user.name` and `user.email` git configs, you can sign your
+commit automatically with `git commit -s`.
+
+## Communications
+
+For general questions, or discussions, please use the 
+IRC group on `irc.freenode.net` called `container-projects`
+that has been setup.
+
+For discussions around issues/bugs and features, you can use the github
+[issues](https://github.com/containers/storage/issues)
+and
+[PRs](https://github.com/containers/storage/pulls)
+tracking system.
+
+<!--
+## Becoming a Maintainer
+
+To become a maintainer you must first be nominated by an existing maintainer.
+If a majority (>50%) of maintainers agree then the proposal is adopted and
+you will be added to the list.
+
+Removing a maintainer requires at least 75% of the remaining maintainers
+approval, or if the person requests to be removed then it is automatic.
+Normally, a maintainer will only be removed if they are considered to be
+inactive for a long period of time or are viewed as disruptive to the community.
+
+The current list of maintainers can be found in the 
+[MAINTAINERS](MAINTAINERS) file.
