 Obtainium allows you to install and update Open-Source Apps directly from their releases pages, and receive notifications when new releases are made available.
 
-Currently supported App sources:
-- GitHub
-- GitLab
-
 Motivation: [Side Of Burritos - You should use this instead of F-Droid | How to use app RSS feed](https://youtu.be/FFz57zNR_M0)
 
+Currently supported App sources:
+- [GitHub](https://github.com/)
+- [GitLab](https://gitlab.com/)
+- [F-Droid](https://f-droid.org/)
+- [IzzyOnDroid](https://android.izzysoft.de/)
+- [Mullvad](https://mullvad.net/en/)
+- [Signal](https://signal.org/)
+- [SourceForge](https://sourceforge.net/)
+- [APKMirror](https://apkmirror.com/) (Track-Only)
+- Third Party F-Droid Repos (URLs ending with `/fdroid/repo`)

 ## Limitations
-- App installs are assumed to have succeeded; failures and cancelled installs cannot be detected.
+- App installs happen asynchronously and the success/failure of an install cannot be determined directly. This results in install statuses and versions sometimes being out of sync with the OS until the next launch or until the problem is manually corrected.
 - Auto (unattended) updates are unsupported due to a lack of any capable Flutter plugin.
-- For GitHub, data is gathered using Web scraping and can easily break due to changes in website design. More reliable methods are either insufficient (GitHub RSS) or subject to rate limits (GitHub API). This may also apply to new sources added in the future.
+- For some sources, data is gathered using Web scraping and can easily break due to changes in website design. In such cases, more reliable methods may be unavailable.
