+# Forgejo Actions Workflows
+
+This directory contains CI/CD workflows for the RateMyClient project.
+
+## docker-build.yml
+
+Automatically builds and pushes Docker images to the Forgejo Container Registry.
+
+### What it does:
+- Triggers on push to `main` branch
+- Builds the Docker image using the Dockerfile
+- Pushes to `forgejo.sivic.me/kevinsivic/ratemyclient`
+- Tags images with:
+  - `latest` (for main branch)
+  - Branch name
+  - Git commit SHA
+  - Semantic versions (if tagged)
+
+### Setup Required:
+
+1. **Enable Actions in Forgejo:**
+   - Go to repository Settings → Actions
+   - Enable Actions for this repository
+
+2. **Configure Forgejo Runner:**
+   - Forgejo needs a runner to execute workflows
+   - Follow: https://forgejo.org/docs/latest/admin/actions/
+
+3. **Access Token (Already configured):**
+   - The workflow uses `${{ secrets.GITEA_TOKEN }}`
+   - This is automatically provided by Forgejo
+
+### Image Location:
+
+After successful build, pull the image:
+```bash
+docker pull forgejo.sivic.me/kevinsivic/ratemyclient:latest
+```
+
+### Deploy with the built image:
+
+Update your docker-compose.yml to use the registry image:
+```yaml
+services:
+  web:
+    image: forgejo.sivic.me/kevinsivic/ratemyclient:latest
+    # Remove 'build: .' line
+```
+
+### Manual Trigger:
+
+You can also trigger builds manually from:
+Repository → Actions → Build and Push Docker Image → Run workflow
