-## Recall.ai - Meeting Transcription API
-
-Meetingnotes runs locally, capturing two streams: system & mic.
-
-If you’re looking for a transcription API for meetings, consider checking out [Recall.ai](
-https://www.recall.ai?utm_source=github&utm_medium=sponsorship&utm_campaign=owengretzinger+meetingnotes), an API that works with Zoom, Google Meet, Microsoft Teams, and more. Recall.ai diarizes by pulling the speaker data and separate audio streams from the meeting platforms, which means 100% accurate speaker diarization with actual speaker names.

 ## Releasing a New Version

-Follow these steps to create a new release with auto-updates:
-
-### Prerequisites
-
- Homebrew packages: `brew install create-dmg sparkle`
- Make scripts executable: `chmod +x scripts/update_version.sh scripts/build_release.sh`
+Production releases are Developer ID signed, notarized by Apple, published to
+[Gitea Releases](https://git.jamesbone.net/coder/meetingnotes/releases), and signed for Sparkle auto-updates.

 ### Release Process

@@ -159,31 +66,36 @@ Follow these steps to create a new release with auto-updates:
   ./scripts/update_version.sh custom 1.2.0
   ```

-2. **Build the release:**
+2. Commit and push the version change to `main`.

-   ```bash
-   ./scripts/build_release.sh
-   ```
+3. Run the `Release` workflow from Gitea Actions on `main` and enter the version without
+   the `v` prefix. The workflow signs and notarizes the app, generates the
+   signed appcast, creates the version tag, and publishes both release assets.

-   This will:
+The app checks
+`https://git.jamesbone.net/coder/meetingnotes/releases/download/latest/appcast.xml`
+and installs later releases automatically through Sparkle.

-   - Clean build the app in Release mode
-   - Create a signed DMG file
-   - Generate the appcast.xml for auto-updates
+### Recovering Meetings

-3. **Create GitHub Release:**
+The first Developer ID signed build may not automatically inherit data from an
+older ad-hoc signed build. In Settings, use **Import Meetings...** and select the
+old `Meetings` folder. After this one-time transition, the stable signing
+identity keeps the same sandbox container across updates.

-   - Go to [GitHub Releases](https://github.com/owengretzinger/meetingnotes/releases)
-   - Click "Create a new release"
-   - Tag: `v1.0.1` (match the version number)
-   - Title: `Meetingnotes v1.0.1`
-   - Upload the DMG and zip files from `releases/` folder
-   - Generate release notes
+### Build runner and GitHub transition

-4. **Update appcast:**
+`.gitea/workflows/build.yml` builds universal macOS artifacts for pushes and pull
+requests to `main`. The shared account-scoped `mac-mini` runner uses the
+`macos-arm64` label. Smoke tests use a separate CI bundle identifier and temporary
+launch preferences and an internal-volume staging directory. Keychain services
+follow the bundle identifier, so CI never reads production credentials; the smoke
+test removes its isolated API token before and after each launch. Release jobs import the original Developer ID certificate
+into a temporary keychain and keep the original Sparkle signing key in Gitea
+Actions secrets. They never publish from a development branch.

-   ```bash
-   git add appcast.xml
-   git commit -m "Update appcast for v1.0.1"
-   git push
-   ```
+Version 1.1.33 moves the embedded update feed to Gitea. After its notarized archive
+is verified, replace the `appcast.xml` asset on the last GitHub release with the
+new appcast. Existing installations discover the Gitea download through that old
+GitHub feed; after installing it, they check Gitea directly. Keep the old GitHub
+repository and its release appcast available for installations that update later.
