Draft, until it has been reviewed.
Waterflow is free software under the GNU Affero General Public License, version 3 (AGPL-3.0). You may run it, study it, change it and share it under that license.
It comes with no warranty. If you run a Waterflow server, you are responsible for it: keeping it updated, securing access to it, backing it up, and the people you let use it.
If you run a changed version of Waterflow for other people, the AGPL requires you to offer them the source code of your changes.
