+## Requirements

+- Enough disk space and alerts about low disk space. If you run out disk space, MongoDB database gets corrupted.
+- SECURITY: Updating to newest Wekan version very often. Please check you do not have automatic updates of Sandstorm or Snap turned off.

+- [Reporting all new bugs immediately](https://github.com/wekan/wekan/issues).
+  New features and fixes are added to Wekan [many times a day](https://github.com/wekan/wekan/blob/devel/CHANGELOG.md).
+- [Backups](https://github.com/wekan/wekan/wiki/Backup) of Wekan database once a day miminum.
+  Bugs, updates, users deleting list or card, harddrive full, harddrive crash etc can eat your data. There is no undo yet.
