Help & Faqs

 How do I install Onyx?
The best way to install Onyx and figure out how it works is to open the INSTALL file included with the download. It will tell you everything about how to get it up and running... and how to use it! Also, check out the README file, it has some good info in it as well. If you need any help, check out our forum, or ask us!
 How do I edit/create a theme?
All themes are stored in public/themes. Take a look at some of the default themes that come with Onyx to get a good idea about how they are structured. As always, if you need any help, let us know.
