 `out.sh` will get you completions of subcommands and flags. Copy it to `/etc/bash_completion.d/` as described [here](https://debian-administration.org/article/316/An_introduction_to_bash_completion_part_1) and reset your terminal to use autocompletion. If you make additional annotations to your code, you can get even more intelligent and flexible behavior.
 
-## Creating your own custom functions
+## Have the completions code complete your 'nouns'
+
+### Static completion of nouns
+
+This method allows you to provide a pre-defined list of completion choices for your nouns using the `validArgs` field.
+For example, if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them. Simplified code from `kubectl get` looks like:
+
+```go
+validArgs []string = { "pod", "node", "service", "replicationcontroller" }
+
+cmd := &cobra.Command{
+	Use:     "get [(-o|--output=)json|yaml|template|...] (RESOURCE [NAME] | RESOURCE/NAME ...)",
+	Short:   "Display one or many resources",
+	Long:    get_long,
+	Example: get_example,
+	Run: func(cmd *cobra.Command, args []string) {
+		err := RunGet(f, out, cmd, args)
+		util.CheckErr(err)
+	},
+	ValidArgs: validArgs,
+}
+```
+
+Notice we put the "ValidArgs" on the "get" subcommand. Doing so will give results like
+
+```bash
+# kubectl get [tab][tab]
+node                 pod                    replicationcontroller  service
+```
+
+### Plural form and shortcuts for nouns
+
+If your nouns have a number of aliases, you can define them alongside `ValidArgs` using `ArgAliases`:
+
+```go
+argAliases []string = { "pods", "nodes", "services", "svc", "replicationcontrollers", "rc" }
+
+cmd := &cobra.Command{
+    ...
+	ValidArgs:  validArgs,
+	ArgAliases: argAliases
+}
+```
+
+The aliases are not shown to the user on tab completion, but they are accepted as valid nouns by
+the completion algorithm if entered manually, e.g. in:
+
+```bash
+# kubectl get rc [tab][tab]
+backend        frontend       database 
+```
+
+Note that without declaring `rc` as an alias, the completion algorithm would show the list of nouns
+in this example again instead of the replication controllers.
+
+### Dynamic completion of nouns
+
+In some cases it is not possible to provide a list of possible completions in advance.  Instead, the list of completions must be determined at execution-time.  Cobra provides two ways of defining such dynamic completion of nouns. Note that both these methods can be used along-side each other as long as they are not both used for the same command.
+
+**Note**: *Custom Completions written in Go* will automatically work for other shell-completion scripts (e.g., Fish shell), while *Custom Completions written in Bash* will only work for Bash shell-completion.  It is therefore recommended to use *Custom Completions written in Go*.
+
+#### 1. Custom completions of nouns written in Go
+
+In a similar fashion as for static completions, you can use the `ValidArgsFunction` field to provide a Go function that Cobra will execute when it needs the list of completion choices for the nouns of a command.  Note that either `ValidArgs` or `ValidArgsFunction` can be used for a single cobra command, but not both.
+Simplified code from `helm status` looks like:
+
+```go
+cmd := &cobra.Command{
+	Use:   "status RELEASE_NAME",
+	Short: "Display the status of the named release",
+	Long:  status_long,
+	RunE: func(cmd *cobra.Command, args []string) {
+		RunGet(args[0])
+	},
+	ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
+		if len(args) != 0 {
+			return nil, cobra.ShellCompDirectiveNoFileComp
+		}
+		return getReleasesFromCluster(toComplete), cobra.ShellCompDirectiveNoFileComp
+	},
+}
+```
+Where `getReleasesFromCluster()` is a Go function that obtains the list of current Helm releases running on the Kubernetes cluster.
+Notice we put the `ValidArgsFunction` on the `status` subcommand. Let's assume the Helm releases on the cluster are: `harbor`, `notary`, `rook` and `thanos` then this dynamic completion will give results like
+
+```bash
+# helm status [tab][tab]
+harbor notary rook thanos
+```
+You may have noticed the use of `cobra.ShellCompDirective`.  These directives are bit fields allowing to control some shell completion behaviors for your particular completion.  You can combine them with the bit-or operator such as `cobra.ShellCompDirectiveNoSpace | cobra.ShellCompDirectiveNoFileComp`
+```go
+// Indicates an error occurred and completions should be ignored.
+ShellCompDirectiveError
+// Indicates that the shell should not add a space after the completion,
+// even if there is a single completion provided.
+ShellCompDirectiveNoSpace
+// Indicates that the shell should not provide file completion even when
+// no completion is provided.
+// This currently does not work for zsh or bash < 4
+ShellCompDirectiveNoFileComp
+// Indicates that the shell will perform its default behavior after completions
+// have been provided (this implies !ShellCompDirectiveNoSpace && !ShellCompDirectiveNoFileComp).
+ShellCompDirectiveDefault
+```
+
+When using the `ValidArgsFunction`, Cobra will call your registered function after having parsed all flags and arguments provided in the command-line.  You therefore don't need to do this parsing yourself.  For example, when a user calls `helm status --namespace my-rook-ns [tab][tab]`, Cobra will call your registered `ValidArgsFunction` after having parsed the `--namespace` flag, as it would have done when calling the `RunE` function.
+
+##### Debugging
+
+Cobra achieves dynamic completions written in Go through the use of a hidden command called by the completion script.  To debug your Go completion code, you can call this hidden command directly:
+```bash
+# helm __complete status har<ENTER>
+harbor
+:4
+Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
+```
+***Important:*** If the noun to complete is empty, you must pass an empty parameter to the `__complete` command:
+```bash
+# helm __complete status ""<ENTER>
+harbor
+notary
+rook
+thanos
+:4
+Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
+```
+Calling the `__complete` command directly allows you to run the Go debugger to troubleshoot your code.  You can also add printouts to your code; Cobra provides the following functions to use for printouts in Go completion code:
+```go
+// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE
+// is set to a file path) and optionally prints to stderr.
+cobra.CompDebug(msg string, printToStdErr bool) {
+cobra.CompDebugln(msg string, printToStdErr bool)
+
+// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE
+// is set to a file path) and to stderr.
+cobra.CompError(msg string)
+cobra.CompErrorln(msg string)
+```
+***Important:*** You should **not** leave traces that print to stdout in your completion code as they will be interpreted as completion choices by the completion script.  Instead, use the cobra-provided debugging traces functions mentioned above.
+
+#### 2. Custom completions of nouns written in Bash
+
+This method allows you to inject bash functions into the completion script.  Those bash functions are responsible for providing the completion choices for your own completions.

 The `BashCompletionFunction` option is really only valid/useful on the root command. Doing the above will cause `__kubectl_custom_func()` (`__<command-use>_custom_func()`) to be called when the built in processor was unable to find a solution. In the case of kubernetes a valid command might look something like `kubectl get pod [mypod]`. If you type `kubectl get pod [tab][tab]` the `__kubectl_customc_func()` will run because the cobra.Command only understood "kubectl" and "get." `__kubectl_custom_func()` will see that the cobra.Command is "kubectl_get" and will thus call another helper `__kubectl_get_resource()`.  `__kubectl_get_resource` will look at the 'nouns' collected. In our example the only noun will be `pod`.  So it will call `__kubectl_parse_get pod`.  `__kubectl_parse_get` will actually call out to kubernetes and get any pods.  It will then set `COMPREPLY` to valid pods!

 # Specify custom flag completion
 
-Similar to the filename completion and filtering using cobra.BashCompFilenameExt, you can specify
-a custom flag completion function with cobra.BashCompCustom:
+As for nouns, Cobra provides two ways of defining dynamic completion of flags.  Note that both these methods can be used along-side each other as long as they are not both used for the same flag.
+
+**Note**: *Custom Completions written in Go* will automatically work for other shell-completion scripts (e.g., Fish shell), while *Custom Completions written in Bash* will only work for Bash shell-completion.  It is therefore recommended to use *Custom Completions written in Go*.

+## 1. Custom completions of flags written in Go
+
+To provide a Go function that Cobra will execute when it needs the list of completion choices for a flag, you must register the function in the following manner:
+
+```go
+flagName := "output"
+cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {

+Notice that calling `RegisterFlagCompletionFunc()` is done through the `command` with which the flag is associated.  In our example this dynamic completion will give results like so:
+
+```bash
+# helm status --output [tab][tab]

+## Generating Fish Completions for your own cobra.Command
+
+Cobra supports native Fish completions generated from the root `cobra.Command`.  You can use the `command.GenFishCompletion()` or `command.GenFishCompletionFile()` functions. You must provide these functions with a parameter indicating if the completions should be annotated with a description; Cobra will provide the description automatically based on usage information.  You can choose to make this option configurable by your users.
+
+### Limitations
+
+* Custom completions implemented using the `ValidArgsFunction` and `RegisterFlagCompletionFunc()` are supported automatically but the ones implemented in Bash scripting are not.
