+#tns resources update
+==========
+
+Usage | Synopsis
+------|-------
+`$ tns resources update` | Defaults to executing `$ tns resources update android`. Updates the App_Resources/Android's folder structure.
+`$ tns resources update android` | Updates the App_Resources/Android's folder structure.
+
+Updates the App_Resources/<platform>'s internal folder structure to conform to that of an Android Studio project. Android resource files and directories will be located at the following paths:
+- `drawable-*`, `values`, `raw`, etc. can be found at  `App_Resources/Android/src/main/res` 
+- `AndroidManifest.xml` can be found at `App_Resources/Android/src/main/AndroidManifest.xml`
+- Java source files can be dropped in at `App_Resources/Android/src/main/java` after creating the proper package subdirectory structure
+- Additional arbitrary assets can be dropped in at `App_Resources/Android/src/main/assets`
+
+### Command Limitations
+
+* The command works only for the directory structure under `App_Resources/Android`. Running `$ tns resources-update ios` will have no effect.
