 The playbook can install and configure [etkecc/synapse-admin](https://github.com/etkecc/synapse-admin) (a [feature-rich](https://github.com/etkecc/synapse-admin#fork-differences) fork of [Awesome-Technologies/synapse-admin](https://github.com/Awesome-Technologies/synapse-admin), community room: [#synapse-admin:etke.cc](https://matrix.to/#/#synapse-admin:etke.cc)) for you.

 💡 **Note**: the latest version of synapse-admin is hosted by [etke.cc](https://etke.cc/) at [admin.etke.cc](https://admin.etke.cc/). If you only need this service occasionally and trust giving your admin credentials to a 3rd party Single Page Application, you can consider using it from there and avoiding the (small) overhead of self-hosting.
