Missing Documentation

There isn't any documentation regarding how to compile a plugin, and cargo-quill itself isn't documented very well.
I'm making this an issue because I don't know how to write good documentation.
Steps to compile a plugin:

1. Install cargo-quill by running cargo install --path quill/cargo-quill in the main folder
2. Use cargo-quill in place of cargo when compiling a plugin - cargo-quill build
3. Possibly use flags like --native, --release or --compression-level N
