 Proof Of Concept to run a Matrix client on Android devices using the Matrix Rust Sdk and Jetpack compose.
 
 The plan is [here](https://github.com/vector-im/element-x-android-poc/issues/1)!

+
+### Modules
+
+This Android project is a multi modules project.
+
+- `app` module is the Android application module. Other modules are libraries;
+- `features` modules contain some UI and can be seen as screen of the application;
+- `libraries` modules contain classes that can be useful for other modules to work.
+
+A few details about some modules:
+
+- `libraries-core` module contains utility classes;
+- `libraries-designsystem` module contains Composables which can be used across the app (theme, etc.);
+- `libraries-elementresources` module contains resource from Element Android (mainly strings);
+- `libraries-matrix` module contains wrappers around the Matrix Rust SDK.
+
+Here is the current module dependency graph:
+
+<!-- To update this graph, run `./tools/docs/generateModuleGraph.sh` (one day the CI will do it hopefully). -->
