+# make sure that your registry container is named registry
+# make sure that your dns has a cname set for registry
+# if you want to generate a registry password create a htpasswd file using e.g.:
+# `docker run --entrypoint htpasswd registry:2 -Bbn ${REGISTRY_USER} ${REGISTRY_PASS} > ${REGISTRY_ROOT}/auth/htpasswd`
+# and then pass it to the registry container using a volume mount
+#
+# Example snippet for a compose file (registry_network is shared with swag):
+# registry:
+#   image: registry:2.8.2
+#   container_name: registry
+#   volumes:
+#     - ${DOCKER_REGISTRY_ROOT}:/var/lib/registry
