+# Vulkan Renderer
+
+This project is a small Vulkan renderer written in C++ (and GLSL) with CMake as the build process.
+It currently can render basic triangles in 2D space with a given colour.
+
+### Build
+
+```
+mkdir build
+cd build
+cmake ..
+cmake --build .
+```
+
+This will work on most operating systems and compile all C++ and GLSL code to their required binary formats.
+Then all you will need to do is run the outputted binary to see the example scene.
+
+### Planed Features
+
+- Texture Support
+- 3D space
+- Free camera
+- Mesh (.obj) loading
