 Godot 4.4 is currently used Version
 
+# Overview
+
+1. Pre-Computed Tile Set's
+   1. Each tile is an index id
+      1. This is because we use a bitset to store the valid neighbors of a tile
+      1. 0 is reserved for empty tiles
+   1. Give the Terrain Generator a set of tiles by index with pre-computed adjacencies for each of the size sides
+   1. Weights can also be supplied to factor in more successful tiles
+1. Pre-Defined Chunk Injection
+   1. Give the Terrain Generator a set of pre-defined tile chunks, grid sections, chunks per section
+      1. Take in a set of Relative Coordinate Chunks
+      1. Take in Grid Sections
+      1. Take in Chunks per Grid Section
+   1. Randomly place chunks into each section
+1. Height Manipulation
+   1. Using [Simplex-Fractal-Noise](https://github.com/SRombauts/SimplexNoise?tab=readme-ov-file#readme)
+   1. Height limitations are applied when collapsing the Wave Function
+1. Collapse the Wave
+   1. Using Wave Function Collapse determine a final grid with Tiles
+1. Output a final 3 dimensional array with a tile index at each location
+1. Use the generated 3d grid to generate a visual representation by iterating through the 3d array and instantiating the tiles in the game world
+
+# Setup
+
+## Windows
+
+1. Setup a C++ Environment
+   1. Possible Setup for VS Code : https://code.visualstudio.com/docs/cpp/config-mingw
+
+Ensure that C++ can run :
+
+```bash
+gcc --version
+g++ --version
+gdb --version
+```
