+# Runs any command from within an `api` container.
+# If no command is given, it runs the application's default command.
+
+# NOTE: This script is intended as a one-command option to run Flagsmith code
+# with no previous setup except from installing Docker.
+
+# Requirements:
+# - Docker
+
+# Examples:
+# - `./run` — runs pending migrations and starts the API HTTP server in dev mode.
+# - `./run bash` — starts a bash shell in the API container.
+# - `./run python manage.py makemigrations` — runs the command in the API container.
+# - `./run flagsmith createsuperuser` — the Flagsmith CLI should be there too!
+# - `./run pytest --sw --pdb tests/unit/test_my_feature.py` — you get it.
