+Depending on whether you are using x64 or arm64, you might need to add either the `x86_64-apple-darwin` or the `aarch64-apple-darwin` target accordingly:

+```sh
+rustup target add x86_64-apple-darwin
+rustup target add aarch64-apple-darwin

+### For Windows
+
+In order to get stuff working later, use the `nightly` branch of Rust:
+
+```sh
+rustup override set nightly

+
+Install the standard Windows target on a Mac (note, that the opposite is currently impossible):
+
+```sh
+rustup target add x86_64-pc-windows-gnu
+```
+
+Use `homebrew` to install mingw-w64:
+
+```sh
+brew install mingw-w64
+```
+
+Now you can build it:
+
+```sh
+cargo build --release --target=x86_64-pc-windows-gnu
