The compile-repo command will already generate a barebones depiction and package file for your repo, but what if you want to add more?

You're in the package-data folder right now, where the script gets all its info from. Start by creating a folder for your tweak (by package identifier, lowercased). For example, for NotiTinter, it would be a folder at package-data/applebetas.ios.tweak.notitinter.

You can specify a rich HTML description for your tweak by creating a description.html file in that folder. It is inside a table view cell, but doesn't have a <p> added to it. The HTML is injected right inside the <li>.

In the same folder, if you leave a file called icon.png, the script will detect this and automatically add this to your repo's package file, making it show in Cydia.

You can create a changelogs folder in your package's data folder, and fill it with .txt files for each version. If your package version is the same as one of the files, it'll be shown on the package depiction page as well for a quick glance. (Example: package-data/applebetas.ios.tweak.notitinter/changelogs/1.0.0-8.txt).

You can also create a screenshots folder in your package's data folder and fill it with image files to be shown on a separate page (in descending alphabetical order).
