This page states the origin, the upstream project, and the scope of modifications, as required by Section 4 of the Apache License 2.0.

Notice of modifications (Apache-2.0 §4)

This distribution modifies upstream Goose as follows:

1. The Electron desktop runtime is replaced by a custom Tauri 2 shell;
