+#### Installation
+
+This plugin **requires Vim 7.0+ built with Python 3.7+ support**. It needs Python 3.7 to
+be able to run _Black_ inside the Vim process which is much faster than calling an
+external command.
+
+##### `vim-plug`
+
 To install with [vim-plug](https://github.com/junegunn/vim-plug):
 
+_Black_'s `stable` branch tracks official version updates, and can be used to simply
+follow the most recent stable version.
+
 ```
 Plug 'psf/black', { 'branch': 'stable' }
 ```
 
+Another option which is a bit more explicit and offers more control is to use
+`vim-plug`'s `tag` option with a shell wildcard. This will resolve to the latest tag
+which matches the given pattern.
+
+The following matches all stable versions (see the
+[Release Process](../contributing/release_process.md) section for documentation of
+version scheme used by Black):
+
+```
+Plug 'psf/black', { 'tag': '*.*.*' }
+```
+
+and the following demonstrates pinning to a specific year's stable style (2022 in this
+case):
+
+```
+Plug 'psf/black', { 'tag': '22.*.*' }
+```

+##### Arch Linux

+you can start using it in Vim after install with no additional setup.
