+# Release Workflow
+# This workflow is triggered when a version tag is pushed and performs the following:
+#
+# 1. Version Verification:
+#    - Checks if the version in version.properties matches the tag version
+#    - Fails if versions don't match, preventing accidental mismatched releases
+#
+# 2. Build Process:
+#    - Only proceeds if version verification passes
+#    - Builds the application and creates release artifacts
+#
+# To create a release:
+# 1. Update version.properties with the new version
+# 2. Commit and push the change
+# 3. Create and push a tag matching the version (e.g., v1.0.0)

+
+          ### Downloads
+          - **ThymeLab-${{ env.VERSION }}.exe**: Windows installer
+          - **thymelab-launcher-${{ env.VERSION }}.jar**: Launcher JAR (requires Java ${{ env.JAVA_VERSION }})
+
+          ### Installation
+          - **Windows**: Run ThymeLab-${{ env.VERSION }}.exe
+            - **Note**: Windows installers are not signed
+            - When installing, you may see a warning about an unknown publisher
+            - This is expected as the installers are unsigned
+            - To proceed with the installation:
+              1. Right-click the installer and select "Properties"
+              2. Go to the "General" tab
+              3. Click "Unblock" if available, then click "OK"
+            
+          - **macOS**: macOS users need to build the installer locally:
+            ```bash
+            git clone https://github.com/thkwag/thymelab-launcher.git
+            cd thymelab-launcher
+            ./gradlew createInstaller -Pos=mac
+            ```
+            The installer will be created in `build/dist/`
+            
+          - **All OS**: Run the JAR file
+            ```bash
+            java -jar thymelab-launcher-${{ env.VERSION }}.jar
+            ```
