 The main way to customize Gitea is by using the `custom` folder. This is the central place to override and configure features.
 
+If you installed Gitea from binary, you can find the `custom` folder next to the binary.
+You should already find it, with a `conf` folder inside, where Gitea stores all the configuration settings provided through the installation steps.

 ## Customizing /robots.txt
 
-To make Gitea serve your own `/robots.txt` (by default, an empty 404 status is served), simply create a file called `robots.txt` in the `custom` folder with the [expected contents](http://www.robotstxt.org/). **Note** that you have to restart Gitea for it to notice the new `robots.txt`.

+To make Gitea serve custom public files (like pages and images), use the folder `custom/public/` as the webroot. Symbolic links will be followed.
+
+For example, a file `image.png` stored in `custom/public`, can be accessed with the url `http://your-gitea-url/image.png`.
 
 ## Changing the default avatar
 
 Place the png image at the following path: `custom/public/img/avatar_default.png`
+
+## Customizing Gitea pages
+
+The `custom/templates` folder allows you to change every single page of Gitea.
+
+You need to be aware of the template you want to change. All templates can be found in the `templates` folder of the Gitea sources.
+
+When you find the correct .tmpl file, you need to copy it in the `custom/templates` folder of your installation, __respecting__ any subfolder you found in the source template.
+
+You can now customize the template you copied in `custom/templates`, being carefully to not break the Gitea syntax.
+Any statement contained inside `{{` and `}}` are Gitea templete's syntax and shouldn't be touch, unless you know what are you doing.
