 # Build System Changes for Android.mk Writers
 
+## Perform validation of Soong plugins
+
+Each Soong plugin will require manual work to migrate to Bazel. In order to
+minimize the manual work outside of build/soong, we are restricting plugins to
+those that exist today and those in vendor or hardware directories.
+
+If you need to extend the build system via a plugin, please reach out to the
+build team via email android-building@googlegroups.com (external) for any
+questions, or see [go/soong](http://go/soong) (internal).
+
+To omit the validation, `BUILD_BROKEN_PLUGIN_VALIDATION` expects a list of
+plugins to omit from the validation.
