-## App Module
-* Keep `AppContext` and `MainActivity`, but the package is unknown and will be change. (Lose git tracking)
+## File Structures
+* `/base` module:
+	* Responsibility: define the base, common and utilities classes.
+	* It can be updated by merging base repository, and will not affect the project modules.
+* `/app` module:
+	* Responsibility: define all the features in your app.
+	* Define `applicationId` as app package name.
+	* Include all resources that app used. (including strings, colors, dimensions, drawables.)
+
+## Dependencies
+* `/app` include `/base` serves as common library that the whole project used.
+
+## Don't do
+Don't add anything to the module other than `/base`, since other modules will change the package to feature, and it will break the merge.
