Documentation
Guides for using Catch and for running your own server.
Catch stores your notes on a server you or someone you trust runs. You use it in a browser, as an installed web app, or through the Android app. This public documentation site is separate from your Catch server: you do not sign in or keep notes here.
User guide
Get the app, sign in, write notes and keep them organized across devices.
Admin guide
Install Catch with Docker, invite people, configure HTTPS, back up and update.
If you are moving from Google Keep, start with Google Keep import. If changes are waiting on your device, read Offline and updates.
These guides describe Catch's capabilities in the latest preview release. Your installed release may be older; check Settings > Update and the changelog when a control described here is missing.
To work on Catch itself, use the repository's development guide and architecture decisions.
