## Overview

This repository is the Android platform/player catalogue and its generator, not Cocoon Shell’s Android application. The main workflow is to define platform and player metadata in YAML, load and transform it into a catalogue, and make that catalogue available to Cocoon, which launches games through emulators. The README also describes broader frontend features, but their implementation is not present in this tree. The graph focuses on the supported catalogue workflow; it does not infer runtime wiring beyond the documentation.

Main entry points: [`tools/build.py`](https://github.com/kansomirai/cocoonfe/blob/main/tools/build.py) (Catalogue generator), [`tools/platforms.py`](https://github.com/kansomirai/cocoonfe/blob/main/tools/platforms.py) (YAML loader), [`android`](https://github.com/kansomirai/cocoonfe/tree/main/android) (Platform and player data), [`tools/yaml_to_json.rb`](https://github.com/kansomirai/cocoonfe/blob/main/tools/yaml_to_json.rb) (YAML parser)
