 `GITEA_TARGET_COMMIT` defaults to the current `HEAD` commit, so overriding it lets you publish from another branch if needed. Whenever those variables are set, the script will create (or reuse) tag `v<version>` and upload both ZIP and DMG as release assets automatically.
 
+If you re-run the release script for the same version, it removes any existing assets with the same filenames before uploading, so you never end up with duplicate ZIP/DMG files on the release page.

 ### Sparkle updates
 
 iKeyMon uses [Sparkle](https://sparkle-project.org/) for macOS-safe updates.
 
 1. Generate an EdDSA key pair once (`./Packages/Sparkle/bin/generate_keys`). Store the private key on-disk (for example `~/.config/Sparkle/iKeyMon.key`, which the build script expects) and copy the public key into the `SUPublicEDKey` entry (see Info.plist notes below).
-2. `./scripts/build_release.sh` signs the ZIP with Sparkle’s `sign_update` tool and invokes `generate_appcast` automatically when the Sparkle variables are present. The generated feed is written to `Sparkle/appcast.xml`, so commit that file after every release. Point `SPARKLE_DOWNLOAD_BASE_TEMPLATE` at your release download prefix to ensure the feed URLs resolve correctly.

The generated feed is written to `Sparkle/appcast.xml`, so commit that file after every release. Point `SPARKLE_DOWNLOAD_BASE_TEMPLATE` at your release download prefix to ensure the feed URLs resolve correctly. The feed stays inside the repo (it is not uploaded as a release asset).
 3. Set `SUFeedURL` in Info.plist (or the corresponding build setting) to the raw URL of `Sparkle/appcast.xml` inside this repo (e.g. `https://git.24unix.net/tracer/iKeyMon/raw/branch/master/Sparkle/appcast.xml`).
 
 Preferences expose Sparkle’s built-in toggles for “Automatically check” and “Automatically download”, and the toolbar button simply calls Sparkle’s “Check for Updates…” sheet.
