-A new geobookmark can be created on current location.

+(Always prefer [F-Droid](https://f-droid.org) build, when possible).
+
+UNOFFICIAL and FOSS Nextcloud Maps client at its earliest stages of developement. Shows your Nextcloud Maps geofavorites in a list and a map.
+Geofavorites can be opened in all apps supporting geo links (i.e. Google Maps, Organic Maps etc...).
+A new geofavorite can be created on current location, by sharing a "geo:" uri from another app or manually picking from the map.
 
 **Requires Maps app to be installed on the Nextcloud instance.**
 
 This work is heavily based on [matiasdelellis's Nextcloud SSO example](https://github.com/matiasdelellis/app-tutorial-android) to implement [Nextcloud single sign on](https://github.com/nextcloud/Android-SingleSignOn).

+## Contributions
+
+### Why isn't this hosted on GitHub?
+
+I'm using a private git server just because I'm worried for the vast majority of open source code being hosted in a server property of Microsoft and being used to train theirs AI.
+I didn't find a better option, BTW the Gitea project is working on implementing federation, so soon it will be possible to contribute using any other gitea server, selfhosted or not.
+
+### How to contribute
+
+The project is open to contribution, but with some limits:
+
+- I'm sorry I can't accept AI-generated contributions. Reviewing a contribution requires time and effort from my side, while generating code with AI requires very little time and produces non reliable code that must be reviewed in detail. This is effectively shifting the work on my side, and in a forced way. If you feel you need a feature but you're not able to implement it by yourself, I prefer you to create an issue in the repository so I can implement it when I can, in a more mantainable way.
+- I prefer to make project-wide changes (i.e. updating Android target, app name and icon, release number...) by myself.
+
+To contribute, you'll have to create an account on this git instance. Unfortunately, I had to disable registration to avoid huge waves of fake accounts created by bots.
+You can request an account writing to daniele.verducci@ichibi.eu
