 ## Building release binaries (maintainers)
 
-Release archives are **Linux ELF** binaries (`speculos-v<version>-linux-<arch>.tar.gz`). CI builds them on native Linux runners (see `.github/workflows/build-speculos.yml`).
+Release archives are **Linux ELF** binaries (`speculos-v<version>-linux-<arch>.tar.gz`). CI builds **linux-amd64** only (see `.github/workflows/build-speculos.yml`); build **linux-arm64** locally with the Docker script below.
 
 On **macOS** (including Apple Silicon) or Windows, use Docker so PyInstaller runs inside Linux:
