-### FAQ/Troubleshooting
+### `PlugInstall!` and `PlugUpdate!`
 
-See [FAQ/Troubleshooting](https://github.com/junegunn/vim-plug/wiki/faq).
+The installer takes the following steps when installing/updating a plugin:
+
+1. `git clone` or `git fetch` from its origin
+2. Check out branch, tag, or commit and optionally `git merge` remote branch
+3. If the plugin was updated (or installed for the first time)
+    1. Update submodules
+    2. Execute post-update hooks
+
+The commands with `!` suffix ensure that all steps are run unconditionally.
