+## Features
+### Clean Code
+Our code is designed to be clean and easy to read, 
+ensuring that it is both maintainable and understandable for developers of all skill levels.
+
+### Cross-Platform
+- [x] Windows
+- [x] Linux
+- [x] MacOS
+
+### Compatibility with Git
+Our implementation is essentially fully compatible with `Git` 
+(developed with reference to the `Git` documentation), 
+including formats such as `objects`, `index`, `pack`, and `pack-index`. 
+Therefore, it can interact seamlessly with `Git` servers (like `push` and `pull`).
+
+### Differences from Git:
+While maintaining compatibility with `Git`, we have made some innovations and changes:
+we use an `SQLite` database to manage loosely structured files such as `config`, `HEAD`, and `refs`, 
+achieving unified management.
