+## User CSS
+
+- Shaarli's apparence can be modified by editing CSS rules in `inc/user.css`. This file allows to override rules defined in the main `inc/shaarli.css` (only add changed rules), or define a whole new theme.
+- Do not edit `inc/shaarli.css`! Your changes would be overriden when updating Shaarli.
+- Some themes are available at https://github.com/shaarli/shaarli-themes.

+
+## RainTPL template
+
+_WARNING - This feature is currently being worked on and will be improved in the next releases. Experimental._
+
+- Find the template you'd like to install (see the list of [available templates|Theming#community-themes--templates](available-templates|Theming#community-themes--templates.html))
+- Find it's git clone URL or download the zip archive for the template.
+- In your Shaarli `tpl/` directory, run `git clone https://url/of/my-template/` or unpack the zip archive.
+    - There should now be a `my-template/` directory under the `tpl/` dir, containing directly all the template files.
+- Edit `data/config.php` to have Shaarli use this template, e.g.
+```php
+$GLOBALS['config'['RAINTPL_TPL'] = 'tpl/my-template/';]('RAINTPL_TPL']-=-'tpl/my-template/';.html)
+```
