 ## Pushing to Registry
 
-Edit the `REGISTRY` variable in `build.sh` or specify it when building:
+The image is automatically built and pushed to GitHub Container Registry via GitHub Actions on every push to `main` and on version tags.
+
+### Manual Push
+
+Set your GitHub token and run the build script:
 
 ```bash
-# for Docker Hub
-REGISTRY="yourusername/"
+export GITHUB_TOKEN=ghp_your_token_here
 ./build.sh
+```
 
-# for private registry
-REGISTRY="your-registry.com/yournamespace/"
-./build.sh
+The script will prompt you to push after building.
+
+### Automated Push (GitHub Actions)
+
+Push to the `main` branch or create a version tag:
+
+```bash
+# Trigger build on push to main
+git push origin main
+
+# Or create and push a version tag
+git tag v1.25-3.6.2
+git push origin v1.25-3.6.2
 ```
