 Every module must have a `name` property, and the value must be unique across
 all Android.bp files.
 
-For a list of valid module types and their properties see
-[$OUT_DIR/soong/docs/soong_build.html](https://ci.android.com/builds/latest/branches/aosp-build-tools/targets/linux/view/soong_build.html).
+The list of valid module types and their properties can be generated by calling
+`m soong_docs`. It will be written to `$OUT_DIR/soong/docs/soong_build.html`.
+This list for the current version of Soong can be found [here](https://ci.android.com/builds/latest/branches/aosp-build-tools/targets/linux/view/soong_build.html).
