 This will build docker images and run them using docker-compose.
 
 Press Ctrl-C when you want to stop it.

+## Details
+
+This runs the following services on their respectively standard ports:
+
+- swh-objstorage
+
+- a `softwareheritage` instance db that stores the Merkle DAG.
+
+- swh-storage (plugged to communicate with the objstorage and the db)
+
+That means, you can start doing the ingestion using those services
+using the same setup described in the getting-started [1].
