 ## A few helpful notes
 
 - Your project needs both `project.godot` and `export_presets.cfg`. Preset names with spaces, such as `Windows Desktop`, are fine.
-- Downloads are checked against Godot's published `SHA512-SUMS.txt` file before anything is extracted.
+- Editor and template downloads come from the [official Godot stable-release assets](https://github.com/godotengine/godot/releases) and are checked against that release's `SHA512-SUMS.txt` before anything is extracted. If a release does not provide an editor for the requested runner architecture, the action fails before downloading either archive.
+- Linux ARM downloads require Godot 4.2 or newer; Windows ARM64 downloads require Godot 4.3 or newer. macOS uses the universal editor archive on both supported architectures.
 - On Linux, make sure the runner has `curl`, `unzip`, and `sha512sum`. macOS needs `curl`, `unzip`, and `shasum`. Windows uses the archive and hashing tools built into PowerShell.
 - The cache includes the editor and the full export-template package. Gitea keeps that cache on each runner by default; an administrator can configure shared storage if several runners should reuse it.
 - This action installs Godot, not every SDK around it. Android, iOS, console, and other platform-specific presets may still need their own SDKs, credentials, or signing setup on the runner.
