Pre-commit steps

• Tested on QEMU and real HW Rasperry Pi.
  • Not needed if it is just a README change or similar.
• Ran ./contributor_setup.sh followed by ./devtool ready_for_publish
  • You'll need Ruby with Bundler and NPM installed locally.
  • If no Rust-related files were changed, ./devtool ready_for_publish_no_rust can be used instead (faster).
  • This step is optional, but much appreciated if done.

I'm not a Chinese speaker, but it checks out in Google Translate at least.
