+# volaTileMidi 🎹✨
+
+A high-performance, cross-platform MIDI visualizer and interactive piano trainer written in modern C++. 
+
+The name is a geeky nod to the C++ `volatile` keyword and the smooth, cascading visual notes (**vola-Tile**) that stream down to your keyboard. It connects directly to your USB MIDI piano to offer real-time interaction with zero perceived latency.
+
+---
+
+## 🚀 Features
+
+* **Real-time MIDI Input:** Connects to any USB/Midi keyboard instantly using `RtMidi`.
+* **Lock-Free Architecture:** Uses a custom Single-Producer Single-Consumer (SPSC) lock-free ring buffer to forward MIDI events from the driver thread to the main loop without blocking or stuttering.
+* **Modern 2D Rendering:** Powered by `SDL3` leveraging GPU acceleration for perfectly smooth rendering at high refresh rates.
+* **Accurate MIDI Parsing:** Pre-calculates MIDI track events from `.mid` files using `libremidi`, converting native MIDI ticks into absolute time seconds while fully respecting mid-song tempo changes.
+* **Resolution Independent:** Uses a logical rendering viewport size ensuring the falling tiles and keyboard stay perfectly proportioned regardless of your window size or monitor aspect ratio.
+* **Cross-Platform:** Built from the ground up to compile and run natively on both **Windows** and **Linux** (ALSA/PipeWire).
+
+---
+
+## 🛠️ Tech Stack & Dependencies
+
+* **Language:** Modern C++ (C++20 recommended)
+* **Build System:** CMake
+* **Windowing & Graphics:** [SDL3](https://github.com/libsdl-org/SDL)
+* **MIDI I/O:** [RtMidi](https://github.com/garyscavone/rtmidi)
+* **MIDI File Parsing:** [libremidi](https://github.com/jcelerier/libremidi)
+
+---
+
+## 🏗️ Architecture Architecture Overview
+
+The core design centers around a `CoreManager` class that orchestrates the engine lifecycle, ensuring a strict separation between hardware input, logic updates, and presentation:
+
+```
+[ USB Piano Input ] ──> (RtMidi Driver Thread / Lambda)
+│
+[ SpscMidiQueue (Lock-Free) ]
+│
+▼
+[ SDL3 Main Loop ] ──> CoreManager::update() ──> CoreManager::render()
+```
+
+1. **Hardware Thread:** `RtMidi` captures key presses via a low-overhead driver callback. It instantly pushes lightweight events into the lock-free queue.
+2. **Main Loop Thread:** The `CoreManager` pumps OS events, consumes all pending live MIDI events, updates the scrolling timeline based on a precise delta time, and renders the active shapes to the screen.
+
+---
+
+## 📦 Building from Source
+
+### Prerequisites
+
+Make sure you have a C++20 compliant compiler, CMake, and the necessary development packages installed.
+
+#### On Linux (Ubuntu/Debian example):
+```bash
+sudo apt update
+sudo apt install build-essential cmake libasound2-dev libjack-jackd2-dev
+# Install SDL3 from source or repository when fully available on your distro
+```
+
+# Clone the repository
+git clone [https://github.com/yourusername/volaTileMidi.git](https://github.com/yourusername/volaTileMidi.git)
+cd volaTileMidi
+
+# Configure CMake
+cmake -B build -DCMAKE_BUILD_TYPE=Release
+
+# Build the project
+cmake --build build --config Release
+
+🗺️ Roadmap / Todo
+[ ] Initialize SDL3 window context and abstract coordinate system viewport.
+
+[ ] Implement the SpscMidiQueue lock-free ring buffer.
+
+[ ] Bind RtMidi with a non-capturing lambda callback forwarding to CoreManager.
+
+[ ] Render the basic 88-key static virtual keyboard.
+
+[ ] Integrate libremidi parser for absolute timeline conversion (Ticks ➔ Seconds).
+
+[ ] Implement the interactive "Practice Mode" where the scrolling pauses until the correct key is pressed.
