+# Installation instructions
+
+## bash + Homebrew
+
+If you're using Homebrew, just run `brew install hub` and you should be all set with auto-completion.
+
+## bash
+
+Open your `.bashrc` file if you're on Linux, or your `.bash_profile` if you're on OS X and add:
+
+```sh
+if [ -f /path/to/hub.bash_completion ]; then
+    . /path/to/hub.bash_completion
+fi
+```
+
+## zsh
+
+Create a new folder for completions:
+
+```sh
+mkdir -p ~/.zsh/completions
+```
+
+Copy the file `/etc/hub.zsh_completion` from the location where you downloaded `hub` to the folder `~/.zsh/completions/` and rename it to `_hub`:
+
+```sh
+cp /path/to/etc/hub.zsh_completion ~/.zsh/completions/ \
+    mv ~/.zsh/completions/hub.zsh_completion ~/.zsh/completions/_hub
+```
+
+Then add the following lines to your `.zshrc` file:
+
+```sh
+fpath=(~/.zsh/completions $fpath) 
+autoload -U compinit && compinit
+```
