 # T3DSR
 Lightweight terminal-based 3d renderer of geometric shapes using ASCII characters.
 
-# Acknowledgments
+## Features
+- ### 3D Math Optimized with SIMD
+    - High-performance vector and matrix operations using SSE on x86_64 and NEON on ARM.
+- ### Demo
+    - A fully rotationg 3d cube rendered in ASCII.
+    - Z-buffering implementation for depth.
 
-I would like to give a thanks to [Unity Test project](https://github.com/ThrowTheSwitch/Unity) for providing an excellent tool. Without it, unit testing would have been much more difficult. 
+## Usage
+
+```bash
+cmake -B build && \
+make -C build && \
+# run demo
+./build/main
+```
+
+# Requirements 
+- C compiler (GCC, Clang, etc...)
+- make and cmake
+
+# Roadmap
+
+This project is intended to be very lightweight, it's mainly an experiment with 3d math and terminal graphics.
+
+**Feel free to fork it and add some features.**
