1. **Add** `git clone https://github.com/Rust-GPU/rust-gpu.git --depth 1` **to the end of** "Clone the `rust-gpu` repository" 2. **Change** "`cargo build --release` in rust-gpu" **into** "`cargo build -r -p rustc_codegen_spirv` in rust-gpu" These small changes may reduce the downloading and compiling time as well as space occupation for new users.
