+### Usage
+
+Add a vim-plug section to your `~/.vimrc` (or `~/.config/nvim/init.vim` for Neovim):
+
+1. Begin the section with `call plug#begin()`
+1. List the plugins with `Plug` commands
+1. `call plug#end()` to update `&runtimepath` and initialize plugin system
+
+#### Example
 
 ```vim
 call plug#begin('~/.vim/plugged')

+### `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.
