+# Personal Game Engine
+
+A modular, event driven 2D game engine, built from scratch to learn engine architecture and low-level graphics programming.
+
+Supports sprite-based animation, Lua scripting, XML-driven definitions and Tiled map creation.
+
+---
+
+## Features
+
+- Event-based animation and sound system
+- Animation and tile-sets supported by texture atlases
+- Map creation and collision map support in Tiled map editor
+- Component-based entity structure
+- Basic audio engine integration via OpenAL (XML definitions)
+- Basic physics system
+- Lua scripted enemy and weapon behavior
+
+---
+
+## Current Status
+
+**Work in Progress** - This project is still under active development, I am currently cleaning up my resource management system for better ease of use for future users of this engine.
+
+---
+
+## Dependencies
+
+- SDL2, SDL2_image
+- OpenGL 3.3
+- sol2 (Lua binding)
+- TinyXML2
+- OpenAL
+- Freetype
+- GLM
+- pkg-config
+- CMake
+
+## Build Instructions
+
+1. Clone the repo (git.wienermeister.net/snakert12345/yupplemayham.git)
+2. Install list of dependencies. Ensure they're available via pkg-config
+3. Build with CMake
+
+```bash
+git clone https://git.wienermeister.net/snakert12345/yupplemayham.git
+cd yupplemayham
+mkdir build && cd build
+cmake ..
+make
+```
+
+---
+
+## Screenshot
+
+![Screenshot](https://wienermeister.net/img/engine_screenshot.png)
+
+---
+
+## Roadmap
+
+- Save/Load system
+- Modular and scalable menu system
+- In-game dialog and conversation systems
+- Expanded combat system
