 # GNOME Deneb
 
-Bootstrap theme for GNOME websites
+[Bootstrap](https://getbootstrap.com/) theme for GNOME websites.
 
 ## Compile the Deneb theme
 
-In order to build this theme, you need to install `npm` in order to retrieve the dependencies (`bootstrap` 
and `fontawesome`) used to build the CSS/JS/Fonts files. To compile SCSS stylesheets, it uses the `sass` 
command line program and `uglifyjs` to compress the JS files.
+In order to build this theme, you need to install `npm` in order to retrieve the dependencies (`bootstrap` 
and `fontawesome`) used to build the CSS/JS/Fonts files. To compile SCSS stylesheets, it uses the `sassc` 
command line program and `uglifyjs` to compress the JS files.
+
+On Fedora, packages are called `sassc`, `uglify-js` and `npm`, as in Alpine Linux (used in the CI process).
 
 To retrieve the necessary dependencies, run: 
  ```bash
  npm install
  ```
 
-And then, if all the other dependencies are installed on your system, you can run the `build_deneb_theme.sh` 
shell script. All the theme files will be stored in the `dist` directory.
+This will download both Bootstrap and Font-Awesome SCSS files. Then, if all the other dependencies are 
installed on your system, you can run the `build_deneb_theme.sh` shell script. All the theme files will be 
stored in the `dist` directory.
+
+This includes:
+
+ * The full `bootstrap` css classes and features
+ * A GNOME specific theme (with adapted colors and classes). An example is shown in the `index.html` file.
+ * Icons provided by the `fontawesome` project. It is used to include some action icons for instance.
