+## Deployment
+
+You can run multiple projects using the `deploy` command. Create a deployment file with the following:
+
+```
+---
+default:
+  - 'app-one'
+  - 'app-two'
+  - 'app-three'
+
+development:
+  - 'app-foo'
+  - 'app-bar'
+```
+
+It will use whatever is defined in the `default` configuration:
+
+`terragov deploy --file integration.yaml --command plan`
+
+Define a specific group to deploy:
+
+`terragov deploy --file integration.yaml --command plan --group development`
+
+This will use the configuration set by all the methods described previously.
 
 ## Development
 
 After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
