+MobileGL is an implementation of a desktop OpenGL library. It aims to provide:
 
 * Full OpenGL state management.
 * A front-end that exposes OpenGL functions.
-* Pluggable backends so the same front-end and state machine can run on different graphics backends.
+* Multiple independent backend implementations, where each backend targets a specific graphics API and remains fully isolated from others.
 
-This project is intended as an implementation/translation layer; it is not a driver nor a GPU firmware replacement currently.

+The repository is organized into following top-level modules:
 
-1. **MG_State** — the OpenGL state machine and related state-management code.
+1. **MG_State** — OpenGL state tracking and state-management logic.
-2. **MG_Impl** — the front-end OpenGL function implementations that mainly use `MG_State` and `MG_Backend`.
+2. **MG_Impl** — front-end OpenGL API implementations that interact with `MG_State` and `MG_Backend`.
-3. **MG_Backend** — backend implementations that perform actual rendering. Example backend: `Direct (OpenGL ES)` backend.
+3. **MG_Backend** — per-backend translation layer that maps front-end OpenGL semantics and state into concrete backend API calls (e.g. OpenGL ES, Vulkan).
 4. **MG_Util** and other utility modules.

    **Notes:**
 
 * The project requires C++23.
-* `MG_Test` and `MG_Benchmark` can only be built with Clang, not GCC. To enforce Clang, use `-DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++`.

 ## Notice
 
 * MobileGL is **not** production-ready currently.
-* Many features required by a full OpenGL 3.3 implementation are still missing or incomplete.
+* Some `OpenGL 3.3 (Core Profile)` features are still missing or under development.
