+### Prerequisites
+**yadm** completion only works if Git completions are also enabled.
 
+### Homebrew
 If using `homebrew` to install **yadm**, completions should automatically be handled if you also install `brew install bash-completion`. This might require you to include the main completion script in your own bashrc file like this:
-
 ```
 [ -f /usr/local/etc/bash_completion ] && source /usr/local/etc/bash_completion
 ```
 
-## Manual installation
+### Manual installation
 Copy the completion script locally, and add this to you bashrc:
 ```
 [ -f /full/path/to/yadm.bash_completion ] && source /full/path/to/yadm.bash_completion
 ```
+
+## zsh completions
+### Homebrew
+If using `homebrew` to install **yadm**, completions should handled automatically.
+
+### Manual installation
+Copy the completion script `yadm.zsh_completion` locally, rename it to `_yadm`, and add the containing folder to `$fpath` in `.zshrc`:
+```
+fpath=(/path/to/folder/containing_yadm $fpath)
+autoload -U compinit
+compinit
+```
+
+### Installation using [zplug](https://github.com/b4b4r07/zplug)
+Load `_yadm` as a plugin in your `.zshrc`:
+```
+fpath=("$ZPLUG_HOME/bin" $fpath)
+zplug "TheLocehiliosan/yadm", rename-to:_yadm, use:"completion/yadm.zsh_completion", as:command, defer:2
+```
