-### Running a Rails console
+### Running interactive commands over SSH
+
+You can run interactive commands, like a Rails console or a bash session, on a server (default is primary, use `--hosts` to connect to another):
+
+```bash
+# Starts a bash session in a new container made from the most recent app image
+mrsk app exec -i bash
+
+# Starts a bash session in the currently running container for the app
+mrsk app exec -i --reuse bash
+
+# Starts a Rails console in a new container made from the most recent app image
+mrsk app exec -i 'bin/rails console'
+```
 
-If you need to interact with the production console for the app, you can use `mrsk app console`, which will start a Rails console session on the primary host. You can start the console on a different host using `mrsk app console --host 192.168.0.2`. Be mindful that this is a live wire! Any changes made to the production database will take effect immeditately.
