 The main way to customize Gitea is by using the `custom` folder. This is the central place to override and configure features.
 
+If you install Gitea from binary, after the installation process ends, you can find the `custom` folder next to the binary.
+Gitea will create the folder for you and prepopulate it with a `conf` folder inside, where Gitea stores all the configuration settings provided through the installation steps (have a look [here](https://docs.gitea.io/en-us/config-cheat-sheet/) for a complete list).
+
+If you can't find the `custom` folder next to the binary, please check the `GITEA_CUSTOM` environment variable, that can be used to override the default path to something else. `GITEA_CUSTOM` might be set for example in your launch script file. Please have a look [here](https://docs.gitea.io/en-us/specific-variables/) for a complete list of environment variables.

 ## 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`.

+
+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.
