+- It **installs and updates 120+ times faster** than the <!--Package Count-->200<!--/Package Count--> packages it consists of.
 - It is more secure because scripts loaded for all extensions are generated by vim-polyglot (ftdetect).
 - Solid syntax and indentation support (other features skipped). Only the best language packs.
 - All unnecessary files are ignored (like enormous documentation from php support).
 - Automatically detect indentation (includes performance-optimized version of [vim-sleuth](https://github.com/tpope/vim-sleuth))
 - Each build is tested by automated vimrunner script on CI. See `spec` directory.

 Individual language packs can be disabled by setting `g:polyglot_disabled` as follows:
 
 ```vim
-let g:polyglot_disabled = ['css']
+let g:polyglot_disabled = ['markdown']
 ```
 
+The list of available languages to disable is shown above.
+
 *Please declare this variable before polyglot is loaded (at the top of .vimrc)*
 
-Please note that disabling a language won't make in your vim startup any faster / slower (only for specific this specific filetype). All plugins are loaded lazily, on demand.
+If you wish to use filetype detection by Vim Polyglot but you'd like to use your own syntax-highlighting plugin, you can append `.plugin` to disabled entry, like so:
+
+```vim
+let g:polyglot_disabled = ['markdown.plugin']
+```
+
+Please note that disabling a language won't make in your vim startup any faster / slower (only for specific this specific filetype). All plugins are lazily loaded only when they are really needed.
 
 Vim Polyglot tries to automatically detect indentation settings (just like vim-sleuth). If this feature is not working for you for some reason, please file an issue and disable it temporarily with:
