+## 🚀 Features
+- 🤖 Automatic - Recast can generate a navmesh from any level geometry you throw at it
+- 🏎️ Fast - swift turnaround times for level designers
+- 🧘 Flexible - detailed customization options and modular design let you tailor functionality to your specific needs
+- 🚫 Dependency-Free - building Recast & Detour only requires a .NET compiler
+- 💪 Industry Standard - Recast powers AI navigation features in Unity, Unreal, Godot, O3DE and countless AAA and indie games and engines
+
+Recast Navigation is divided into multiple modules, each contained in its own folder:
+
+- `DotRecast.Recast`: Navmesh generation
+- `DotRecast.Detour`: Runtime loading of navmesh data, pathfinding, navmesh queries
+- `DotRecast.Detour.TileCache`: Navmesh streaming. Useful for large levels and open-world games
+- `DotRecast.Detour.Crowd`: Agent movement, collision avoidance, and crowd simulation
+- `DotRecast.Recast.Dynamic`: robust support for dynamic nav meshes combining pre-built voxels with dynamic objects which can be freely added and removed
+- `DotRecast.Recast.Extras`: simple tool to import navmeshes created with [A* Pathfinding Project](https://arongranberg.com/astar/)
+- `DotRecast.Recast.Toolset`: sdk
+- `DotRecast.Recast.Demo`: Standalone, comprehensive demo app showcasing all aspects of Recast & Detour's functionality
+- `test/DotRecast.*.Test`: Unit tests
 
 
 ## DotRecast.Recast
 
 Recast is state of the art navigation mesh construction toolset for games.
 
-Recast is...
-* 🤖 **Automatic** - throw any level geometry at it and you will get a robust navmesh out
-* 🏎️ **Fast** - swift turnaround times for level designers
-* 🧘 **Flexible** - easily customize the navmesh generation and runtime navigation systems to suit your specific game's needs.
-
 Recast constructs a navmesh through a multi-step rasterization process:
 
 1. First Recast voxelizes the input triangle mesh by rasterizing the triangles into a multi-layer heightfield.
