  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
  6. The toolchain should now be usable via +esp, see the shorthand syntax: https://rust-lang.github.io/rustup/overrides.html#toolchain-override-shorthand
