Raw links are also another option for using the theme, and most client mod supports them, but there are some inconveniences. For instance, when the theme gets updated, you will lose all the customization that you did on top of Chillax. So they are not recommended when it comes to customizations.

To overcome this issue, we recommend you to fork the Chillax repository and make changes in the newly forked repository and use the raw link of the forked repository. This way you will have the full control over update/patch and there will be no surprises.
