+# Maintenance Notice
+
+I, [Florian Gilcher](https://github.com/skade), am currently the main maintainer of `async-tls`. Due to general workload, I would like the hand the maintenance off to someone else carrying the general vision of `async-tls`:
+
+* Runtime-independence
+* Backend-independence (currently not implemented)
+* Focused on _use-case based_ configuration rather then exposing all configurations
+
+I expect applicants for maintainership to present a committment of at least 4h of time/week initially, so I recommend getting corporate backing first.

+
+Please reach out to me at [through email](mailto:[email protected]).
