+Gitea Actions for Docker builds
+
+This folder contains workflows for building and pushing Docker images to the Gitea Container Registry.
+
+Setup
+- Ensure Gitea Actions is enabled in your instance and for this repo.
+- Create the following repository secrets:
+  - REGISTRY_HOST: your Gitea host (e.g., gitea.example.com)
+  - REGISTRY_OWNER: your namespace/user/org (e.g., ryan)
+  - REGISTRY_REPO: repository name (e.g., noisedash)
+  - REGISTRY_USERNAME: registry username
+  - REGISTRY_PASSWORD: registry password or a scoped token
+
+Notes
+- The workflow builds on pushes to main/master/dev and on tags v*.*.*.
+- It produces multi-arch images (amd64, arm64). Adjust platforms if not needed.
+- Image name resolves to: ${REGISTRY_HOST}/${REGISTRY_OWNER}/${REGISTRY_REPO} with tags derived from branch/tag/sha.
