+# WHAT IS NEEDED FOR THE MIGRATION:
+#
+# - $(SQLDB): a dump of the SQL database (format: login password domain)
+#
+# HOW MIGRATION WORKS, STEP BY STEP (`migration` rule):
+#
+# 1. migration-file    -> create the $(USER_DB) file
+# 2. migrate-all-users -> migrate all user accounts
+#
+# AFTER THE `migration` RULE: go to the dnsmanagerd repository and follow instructions.
