+## Project Overview
+
+FastCast2 is a Roblox projectile library written in Luau, providing high-performance raycasting, blockcasting, and spherecasting with parallel scripting support. It is an unofficial continuation of the original FastCast library.
+
+- **Language**: Luau (Roblox)
+- **Build Tool**: Rojo (`rojo sync`, `rojo serve`)
+- **Documentation**: Moonwave
+- **Repository**: https://github.com/weenachuangkud/FastCast2
+
+## Development Commands
+
+- **Sync to Roblox**: `rojo sync -o <place-name>`
+- **Serve live**: `rojo serve` (then connect via Studio → Plugins → Rojo)
+- **Build docs**: `moonwave build`
+- **Publish docs**: `moonwave build --publish`
+

+
+## Testing
+
+There are no automated tests. Testing is manual via Roblox Studio.
+
+## Code Style
+
+- Luau static typing throughout
+- PascalCase for types, camelCase for variables/functions
+- Two-space indentation
+- SoA (Structure of Arrays) pattern for simulation data
