 To apply our modifications and compile Mostlymatter, please have a look at [MOSTLYMATTER_HOW_TO.md](MOSTLYMATTER_HOW_TO.md).
 
+**Important**: Framasoft has not time or competences to create or maintain a fork heavier than that.
+
+We can’t keep the SSO working, for exemple, as asked in [issue #4](https://framagit.org/framasoft/framateam/mostlymatter/-/issues/4) and can’t accept contributions for that, as asked in [issue #10](https://framagit.org/framasoft/framateam/mostlymatter/-/issues/10).
+We don't have the necessary competences neither in Go or SSO to make sure things are done properly, and we want to keep following upstream new versions fast and simple.
+
+If you’re working on a SSO-capable fork, please let us now so we can point people to it 🙂
