1. Clone https://github.com/esp-rs/rust
2. Ensure deps are met before starting the installation process, see the README.
3. Run ./configure --experimental-targets=Xtensa --release-channel=nightly --enable-extended --tools=clippy,cargo,rustfmt
4. Start the build with ./x.py build --stage 2
5. Link the custom toolchain to rustup:

      rustup toolchain link esp build/$HOST/stage2
   

Where $HOST is your machines triple, i.e x86_64-unknown-linux-gnu
