+## Basic operations
+### Initialize
+
+To start a local Postgres database container in a detached state and run any
+pending migrations, run `make init-db`. During initial setup, `init-db` is called
+automatically when running `make init`.
+
+### Start
+
+To only start the database container, run the following command:
+
+```sh
+make start-db
+```
+This command is not needed when starting the application with `make start`
+
+### Destroy and reinitialize
+
+To clean the database, use the following command:
+
+```sh
+make db-recreate
+```
+
+This will remove _all_ docker project volumes, rebuild the database volume, and 
+run all pending migrations. Once completed, only the database container will be 
+running. Simply run `make start` to bring up all other project containers.
