 # Shrooms VB (native)

-An SDL-based implementation of shrooms-vb.
+A native implementation of shrooms-vb. Written in Rust, using winit, wgpu, and Dear ImGui. Should run on any major OS.

 ## Setup

 Install the following dependencies:
- - `gcc` (or MinGW on Windows) (or whatever, just set `CC`)
- - `pkg-config`
- - sdl2
+ - `cargo`

 Run
 ```sh
-make build
-```
+cargo build --release
+```
+
+The executable will be in `target/release/shrooms-vb[.exe]`
