+```
+~$ flutter pub get
+
+~$ flutter run           # for debug
+~$ flutter build apk     # release build (fat apk)
+```
+
+## Contributing
+The entire app and even the [online sync api](https://github.com/ATechnoHazard/potatosync) is completely open source.  
+Feel free to open a PR to suggest fixes, features or whatever you want, just remember that PRs are subjected to manual review so you gotta wait for actual people to look at your contributions
