+## Managing squad members
+
+You basically have 3 options for managing squad members.
+
+### 1. Edit the `databse/init.sql` file
+
+You can edit the database initialization script and add `INSERT` statements to
+insert your squad members.
+
+### 2. Exec into the Postgres container
+
+You can also exec into the running Postgres container to use `psql` to `INSERT` the
+squad members:
+
+```shell
+docker compose exec db psql -U postgres
+```
+
+That command will start a `psql` console where you can issue your database commands.
+
+Make sure to replace `postgres` by whatever value you've configured as the
+database user, if any. `postgres` is the default one.
+
+### 3. Use the provided CLI
+
+There is a Docker image that packages a CLI tool to manage your squad members.
+You can run it with the following command:
+
+```shell
+docker run -it --network host aloussase69/squad-rotation-bot-cli
+```
