 HabitTrove is a gamified habit tracking application that helps you build and maintain positive habits by rewarding you with coins, which you can use to exchange for rewards.
 
-> **⚠️ Important:** HabitTrove is currently in beta. Please regularly backup your `data/` directory to prevent any potential data loss.

+## Differences to Upstream
 
-Want to try HabitTrove before installing? Visit the public [demo instance](https://demo.habittrove.com) to experience all features without any setup required. (do not store personal info. Data on the demo instance is reset daily)
+I generally try to keep the `main` branch up to date with upstream features, merging tagged versions and mapping them to `<upstream-version>.0`.
+
+In this version I've taken steps to ensure a smoother experience and decreased the chance of the program bricking itself. This doesn't mean that it's completely stable, but I've fixed the most glaring bugs I encountered.
+
+Differences (as of writing) are:
+- resolved linting problems so you can actually commit things
+- added missing dependency
+- refactored adding habit modal to cause less errors
+- resolved undefined error
+- replaced dockerhub release flow with github
+- miscellaneous refactorings
+- split habits & tasks page into two different pages
+- only display "show all" if there are more than 4 entries
