 ## Configuration
 
+### Using .env file to load required environment variables
+
+MRSK uses [dotenv](https://github.com/bkeepers/dotenv) to automatically load environment variables set in the `.env` file present in the application root. This file can be used to set variables like `MRSK_REGISTRY_PASSWORD` or database passwords. But for this reason you must ensure that .env files are not checked into Git or included in your Dockerfile! The format is just key-value like:
+
+```bash
+MRSK_REGISTRY_PASSWORD=pw
+DB_PASSWORD=secret123
+```
+
 ### Using another registry than Docker Hub
 
 The default registry is Docker Hub, but you can change it using `registry/server`:

 ### Using accessories for database, cache, search services
 
 You can manage your accessory services via MRSK as well. The services will build off public images, and will not be automatically updated when you deploy:

 ```
 
-### 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.
