Field notes
The homepage separates firmware and utilities from a short guide section, and links readers to the project’s GitHub. Its first listed walkthrough follows a firmware change in seven steps, pairing original evidence with animated diagrams and an offline Python exercise. The releases area currently says downloads and verified release details will appear there, so the page describes a project whose release index is not yet populated.
