+## Shell Completion
+
+Most people like to have shell completion on the command line. In other words, when you're typing a command, you can hit <TAB> and the shell will show you what the options are. For example, if you type `ddev <TAB>`, you'll see all the possible commands. `ddev debug <TAB>` will show you the options for the command. And `ddev list -<TAB>` will show you all the flags available for `ddev list`.
+
+Shells like bash and zsh need help to do this though, they have to know what the options are. DDEV-Local provides the necessary hint scripts, and if you use homebrew, they get installed automatically. But if you use oh-my-zsh, for example, you may have to manually install the hint script.
+
+### tar Archive of Completion Scripts for Manual Deployment
+
+Although most people will use techniques like homebrew for installation, a tar archive of the shell completion scripts is available in each release, called "ddev_shell_completion_scripts.<version>.tar.gz". If you need to manually install, you can download and untar the scripts, then copy them as needed to where they have to go. For example, `sudo cp ddev_bash_completion.sh /etc/bash_completion.d/ddev`.
+
+Note that scripts for the fish shell and Windows Powershell are also provided, but no instructions are given here for deploying them.
+
+## Bash Completion
+
+**Bash Completion with Homebrew**: The easiest way to use bash completion on either macOS or Linux is to install with homebrew. `brew install bash-completion`. When you install it though, it will warn you with something like this, which may vary on your system.
+
+```bash
+Add the following line to your ~/.bash_profile:
+     [[ -r "/usr/local/etc/profile.d/bash_completion.sh" ]] && . "/usr/local/etc/profile.d/bash_completion.sh"
+```
+
+*You need to add the suggested line to your ~/.bash_profile or ~/.profile to get it to work*, and then in the current shell you need tou `source ~/.bash_profile` or `source ~/.profile` to make it take effect. (You can also just open a new shell window.)
+
+Then, if you're installing ddev from homebrew, each new release will automatically get a refreshed completions script.
+
+**Bash Completion without Homebrew**: The completion script is exactly the same, it's just that you have to install it yourself. Each system may have a slightly different technique, and you'll need to figure it out. On Debian/Ubuntu, you would use [these instructions](http://crsouza.com/2008/07/28/enabling-bash-autocompletion-on-debian/) to enable bash-completion, and then `sudo mkdir -p /etc/bash_completion.d && sudo cp ddev_bash_completion.sh /etc/bash_completion.d`. This deploys the ddev_bash_completion.sh script where it needs to be. Again, every Linux distro has a different technique, and you may have to figure yours out.
+
+### Zsh Completion
+
+**Zsh Completion with Homebrew**: This works exactly the same as bash completion. `brew install zsh-completion`. You'll get instructions something like this:
+
+```bash
+  if type brew &>/dev/null; then
+    FPATH=$(brew --prefix)/share/zsh-completions:$FPATH
+
+    autoload -Uz compinit
+    compinit
+  fi
+
+You may also need to force rebuild `zcompdump`:
+
+  rm -f ~/.zcompdump; compinit
+
+Additionally, if you receive "zsh compinit: insecure directories" warnings when attempting
+to load these completions, you may need to run this:
+
+  chmod go-w '/usr/local/share'
+```
+
+So follow those instructions and your zsh should be set up.
+
+### Oh-My-Zsh Completion
+
+If you installed zsh with homebrew, ddev's completions will be automatically installed when you `brew install ddev`.
+
+Otherwise, Oh-My-Zsh may be set up very differently in different places, so as a power zsh user you'll need to put ddev_bash_completion.sh where it belongs. `echo $fpath` will show you the places that it's most likely to belong. An obvious choice is ~/.oh-my-zsh/completions if that exists, so you can `mkdir -p ~/.oh-my-zsh/completions && cp ddev_zsh_completions.sh ~/.oh-my-zsh/completions/_ddev` and then `autoload -Uz compinit && compinit`.

 `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!

-## 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.
-
 ## Mark flags as required
 
 Most of the time completions will only show subcommands. But if a flag is required to make a subcommand work, you probably want it to show up when the user types [tab][tab].  Marking a flag as 'Required' is incredibly easy.

 # 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) {
+	return []string{"json", "table", "yaml"}, cobra.ShellCompDirectiveDefault
+})
+```
+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]
+json table yaml
+```
+
+### Debugging
+
+You can also easily debug your Go completion code for flags:
+```bash
+# helm __complete status --output ""
+json
+table
+yaml
+:4
+Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
+```
+***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 in the above section.
+
+## 2. Custom completions of flags written in Bash
+
+Alternatively, you can use bash code for flag custom completion. Similar to the filename
+completion and filtering using `cobra.BashCompFilenameExt`, you can specify
+a custom flag completion bash function with `cobra.BashCompCustom`:

 	annotation := make(map[string][]string)

+## 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.

+There are helper functions available to get the value stored in a Flag if you have a FlagSet but find
+it difficult to keep up with all of the pointers in your code.
 If you have a pflag.FlagSet with a flag called 'flagname' of type int you
 can use GetInt() to get the int value. But notice that 'flagname' must exist
 and it must be an int. GetString("flagname") will fail.
