+Here is a lay summary, but check the license for legal definitions and responsibilities.

+- 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.
