Subject: [PATCH] Document command-line completion installation

This is a draft based on [the same doc for docker-compose](https://github.com/docker/compose/blob/master/docs/completion.md). It still needs changes, but will get the thing moving.

+# Command-line Completion
+
+Docker Machine comes with [command completion](http://en.wikipedia.org/wiki/Command-line_completion)
+for the bash shell.
+
+## Installing Command Completion
+
+### Bash
+
+Make sure bash completion is installed. If you use a current Linux in a non-minimal installation, bash completion should be available.
+On a Mac, install with `brew install bash-completion`
+
+Place the completion scripts in `/etc/bash_completion.d/` (`` `brew --prefix`/etc/bash_completion.d/`` on a Mac), using e.g.
+
+    files=(docker-machine docker-machine-wrapper docker-machine-prompt)
+    for f in "${files[@]}"; do
+      curl -L https://raw.githubusercontent.com/docker/machine/v$(docker-machine --version | awk 'NR==1{print $(NF-1)}')/contrib/completion/bash/$f.bash > `brew --prefix`/etc/bash_completion.d/$f
+    done
+
+Completion will be available upon next login.
+
+<!--
+### Zsh
+
+**Note: there does not seem to be any Zsh completion file yet, but when there is, documentation could look like this.**
+
+Place the completion scripts in your `/path/to/zsh/completion`, using e.g. `~/.zsh/completion/`
+
+    mkdir -p ~/.zsh/completion
+    files=(docker-machine docker-machine-wrapper docker-machine-prompt)
+    for f in "${files[@]}"; do
+      curl -L https://raw.githubusercontent.com/docker/machine/v$(docker-machine --version | awk 'NR==1{print $(NF-1)}')/contrib/completion/zsh/$f > ~/.zsh/completion/_$f
+    done
+
+Include the directory in your `$fpath`, e.g. by adding in `~/.zshrc`
+
+    fpath=(~/.zsh/completion $fpath)
+
+Make sure `compinit` is loaded or do it by adding in `~/.zshrc`
+
+    autoload -Uz compinit && compinit -i
+
+Then reload your shell
+
+    exec $SHELL -l
+
