+# License
+
+Gearslip is licensed under the **GNU Affero General Public License v3.0** (see `LICENSE`).
+
+In short: you're free to use, run, and modify it. If you modify it — or run a modified
+version as a service others use over a network — the AGPL requires you to make your source
+changes available on the same terms. That obligation follows the code even when you don't
+redistribute a binary, which is what makes the AGPL fit for something that can run as a
+background service.
+
+## Commercial licensing
+
+If the AGPL's terms don't work for you — for example, you want to use Gearslip privately
+without being required to publish your changes — a separate commercial license is available
+directly from the author. Terms (including any restrictions on modification) are set on a
+case-by-case basis. Contact me though Matrix (on my profile) to discuss one.
