+### Usage
+
+Add a vim-plug section to your `~/.vimrc` (or `init.vim` for Neovim)
+
+1. Begin the section with `call plug#begin()`
+1. List the plugins with `Plug` commands
+1. End the section with `call plug#end()`
+
+For example,
+
+```vim
+call plug#begin()
+
+" List your plugins here
+Plug 'tpope/vim-sensible'
+
+call plug#end()
+```
+
+Reload the file or restart Vim, then you can,
+
+* `:PlugInstall` to install the plugins
+* `:PlugUpdate` to install or update the plugins
+* `:PlugDiff` to review the changes from the last update
+

-### Usage
+### More examples
 
-Add a vim-plug section to your `~/.vimrc` (or `stdpath('config') . '/init.vim'` for Neovim)
+The following examples demonstrate the additional features of vim-plug.
 
-1. Begin the section with `call plug#begin([PLUGIN_DIR])`
-1. List the plugins with `Plug` commands
-1. `call plug#end()` to update `&runtimepath` and initialize plugin system
-    - Automatically executes `filetype plugin indent on` and `syntax enable`.
-      You can revert the settings after the call. e.g. `filetype indent off`, `syntax off`, etc.
-1. Reload the file or restart Vim and run `:PlugInstall` to install plugins.

-> [!NOTE]
-> #### Should I set up on-demand loading?
->
-> You probably don't need to.
->
-> A properly implemented Vim plugin should already load lazily without any
-> help from a plugin manager (`:help autoload`). So there are few cases where
-> these options actually make much sense. Making a plugin load faster is
-> the responsibility of the plugin developer, not the user. If you find
-> a plugin that takes too long to load, consider opening an issue on the
-> plugin's issue tracker.
->
-> Let me give you a perspective. The time it takes to load a plugin is usually
-> less than 2 or 3ms on modern computers. So unless you use a very large
-> number of plugins, you are unlikely to save more than 50ms. If you have
-> spent an hour carefully setting up the options to shave off 50ms, you
-> will have to start Vim 72,000 times just to break even. You should ask
-> yourself if that's a good investment of your time.
->
-> Make sure that you're tackling the right problem by breaking down the
-> startup time of Vim using `--startuptime`.
->
-> ```sh
-> vim --startuptime /tmp/log
-> ```
->
-> On-demand loading should only be used as a last resort. It is basically
-> a hacky workaround and is not always guaranteed to work.
-
-> [!TIP]
-> You can pass an empty list to `on` or `for` option to disable the loading
-> of the plugin. You can manually load the plugin using `plug#load(NAMES...)`
-> function.
