# Installing AppThemes **The first thing you need to do is download AppThemes.** AppThemes are content blocks used to create websites. In the Rocket Admin you can download the default AppThemes. A default set of Appthemes has been made using W3.CSS, called "AppThemes-W3-CSS". https://github.com/Rocket-CDS/AppThemes-W3-CSS ### Step 1  ### Step 2  # Adding another Collection of AppThemes If you want your own set of AppThemes or you want to download another set of AppThemes you can add a source repository for AppThemes.  The repo must be in GitHub. If public you just need to add the GitHub URL. ### Step1 - Get the URL from GitHub  ### Step 2 - Add to the Rocket Admin.  The new GitHub repo will now be available on the download AppTheme Page. ### Private Repo GitHub private repos can also be used, you need to create a GitHub Token for the repo and add it to the Repo information.
