 This Guide shows you the different ways to get started with using Strudel in your own project.
 
+## Respect the license
+
+First, please take a moment to understand Strudel's free/open source license,
+[AGPL-3.0](https://www.gnu.org/licenses/agpl-3.0.en.html).
+
+Here is a lay summary, but check the license for legal definitions and responsibilities.
+
+- You can distribute modified versions if you keep track of the changes and the date you made them.
+- You must license derivative work under the same license.
+- Source code must be distributed along with web publication.
+
+Among other things, it means that when you share your work, the whole application must be shared under the same free/open source license, or one compatible with it. This is because we want Strudel to stay free/open source. In other words, you are not permitted to distribute integrations of Strudel with libraries or other code that does not have a compatible free/open source license.
+
+This also applies to clones informed by reading Strudel's source code, as legally speaking, that counts as a 'derivative work'. Again, please [read the licence](https://www.gnu.org/licenses/agpl-3.0.en.html) for details.
