+As general background, `OWNERS` files expedite code reviews by helping code
+authors quickly find relevant reviewers, and they also ensure that stakeholders
+are involved in code changes in their areas.
+
+The structure of `frameworks/base/` is unique among Android repositories, and
+it's evolved into a complex interleaved structure over the years.  Because of
+this structure, the best place to authoritatively define `OWNERS` can vary
+wildly, but here are some common patterns:
+
+* `core/java/` contains source that is included in the base classpath, and as
+such it's where most APIs are defined:
+  * `core/java/android/app/`
+  * `core/java/android/content/`
+* `services/core/` contains most system services, and these directories
+typically have more granularity than `core/java/`, since they can be refactored
+without API changes:
+  * `services/core/java/com/android/server/net/`
+  * `services/core/java/com/android/server/wm/`
+* `services/` contains several system services that have been isolated from the
+main `services/core/` project:
+  * `services/appwidget/`
+  * `services/midi/`
+* `apex/` contains Mainline modules:
+  * `apex/jobscheduler/`
+  * `apex/permission/`
+* Finally, some teams may have dedicated top-level directories:
+  * `media/`
+  * `wifi/`
+
+Area maintainers are strongly encouraged to list people in a single
+authoritative `OWNERS` file in **exactly one** location.  Then, other paths
+should reference that single authoritative `OWNERS` file using an include
+directive.  This approach ensures that updates are applied consistently across
+the tree, reducing maintenance burden.
