 # How to use:
 
-Beyond switching original CSS file with the one in this repository you should also add `head-include` line in your `cgitrc` file.
-For example:
+Place `cgit-main.css`, `cgit-responsive.css`, and `head.html` alongside your
+existing `cgit.css` file. These responsive css rules are _additive_ to the
+default `cgit.css`.
+
+Update your `cgitrc` to set the `css` and `head-include` directives. For example:
+
+```
+css=/cgit-main.css
+head-include=/usr/share/cgit/head.html
+```
+
+If you already have a `head-include` set, just make sure to include the
+appropriate viewport meta tag:
 
 ```
-head-include=/usr/share/webapps/cgit/head.html
+<meta name="viewport" content="width=device-width initial-scale=1.0"/>
 ```
