+# Rules of code ownership
+# -----------------------
+# 1. Ideally all files in this repository have an owner - it is accepted that this is unlikely to happen
+# 2. We avoid broad ownership rules as much as possible and prefer more granular assignments
+# 3. Applications can be co-owned. If they are co-owned we should:
+#     2.1 Have one ownership rule for the entire application first, pointing to all teams owning the application (1)
+#     2.2 Have granular rules as good as possible to different parts of the application code, which take precedence over the broader rules (order of rules definition is important) (2)
+# 4. This file is grouped by applications and/or folders not by teams
+#     4.1 The order of rules within this file should match the default directory ordering
