Why it fits
Both Desktop Editors and Docs Community Edition carry GNU AGPL version 3 with additional terms appended by Ascensio System SIA. The Desktop Editors are free to install, and Docs Community Edition is free to self-host for private use under the AGPL.

Getting started
Prerequisites (from the official docs):
- Desktop Editors: a Windows, macOS or Linux computer
- Docs Community Edition: a server with Docker, at least a dual-core 2 GHz CPU, 4 GB RAM, 40 GB free disk and 4 GB swap (official requirements)
- Docs needs a host application for file storage and sharing, for example Nextcloud; a built-in test example exists for trying it out
- A JWT secret that you set yourself, and HTTPS (the image can obtain a Let's Encrypt certificate) for internet use
Steps:
- Generate a JWT secret of your own (do not leave the example value).
- Start the onlyoffice/documentserver container with that JWT_SECRET, as in the Docker guide.
- Open http://<server>/welcome to confirm Docs is running, then connect it to a host app such as Nextcloud with the same secret.

Notes
The LICENSE files add terms under AGPL Section 7: keep all copyright and attribution notices; mark modified versions as modified and as based on ONLYOFFICE by Ascensio System SIA; show these notices in the user interface; no trademark rights are granted (see the ONLYOFFICE Trademark Policy); non-code elements such as illustrations and icons are CC BY-SA 4.0. Source file headers state SPDX-License-Identifier: AGPL-3.0-only. ONLYOFFICE's license FAQ says the original logo may not be removed from its products. The README lists Community Edition as "up to 20 recommended" users; the current docs state no hard connection limit. Mobile web editors are listed as not included in Community Edition. The Desktop Editors are a normal app install; self-hosting Docs Community Edition takes server and Docker experience.
