-**To build**: `cargo rustc --release`
+On windows and linux, you can build normally with `cargo build --release`. On Mac Os, you need to set additional linker arguments. One option is to compile with `cargo rustc --release -- -C link-arg=-undefined -C link-arg=dynamic_lookup`, the other is to create a `.cargo/config` with the following content: 
 
-**On a Mac**: `cargo rustc --release -- -C link-arg=-undefined -C link-arg=dynamic_lookup`

 Also on macOS, you will need to rename the output from \*.dylib to \*.so. On Windows, you will need to rename the output from \*.dll to \*.pyd.
