+# Future Features
+
+SirTunnel is intended to be a minimal tool. As such, I'm unlikely to add many
+features moving forward. However, the simplicity makes it easier to modify
+for your needs. If you find a feature missing, maybe one of the forks below
+has what you need or gives you some ideas:
+
+* https://github.com/matiboy/SirTunnel adds functionality to help multiple
+  users avoid overwriting each others' tunnels.
+* https://github.com/daps94/SirTunnel implements tunnel checking and auto
+  cleanup to address issue with stale tunnels.
