Update GITEA_SETUP.md for binary-only CI/CD pipeline

- Clarify Docker is not required for CI/CD
- Note that Docker images are built manually
- Simplify troubleshooting section
- Remove Docker setup instructions from setup guide

 ### Installing Docker on the Runner (Optional)
 
-If you want to build Docker images as part of your releases, install Docker on the runner:
+Docker is **not required** for the CI/CD pipeline. Binary builds work without Docker.
+
+If you want to manually build Docker images:
 
 ```bash
-# Install Docker
+# Build server image
-curl -fsSL https://get.docker.com -o get-docker.sh
+docker build -t nerd-monitor-server -f Dockerfile.server .
-sudo sh get-docker.sh
 
-# Add permissions for the runner user to use Docker
+# Build agent image
-sudo usermod -aG docker $USER
+docker build -t nerd-monitor-agent -f Dockerfile.agent .
 
-# Verify Docker is working
+# Or use docker-compose for both
-docker --version
+docker-compose build
-
+docker-compose up
-# Note: You may need to logout and login for group permissions to take effect
 ```
 
-**Without Docker**: The binary builds will still work. Only Docker image generation will be skipped (the workflow will show a warning but still succeed).

 ## What Happens Next
 
 Once you've set everything up:
 
 1. **Every push to main/master** triggers the build job:
-   - Compiles all platform binaries
+   - Compiles all platform binaries (Linux, macOS, Windows)
-   - Attempts to build Docker images (skips if Docker unavailable)
+   - Creates SHA256 checksums
-   - Uploads artifacts as build artifacts
+   - Artifacts available for 30 days
 
 2. **Every git tag push** (e.g., `v1.0.0`) triggers the full release:
    - Does all of the above
    - Creates a Gitea Release
-   - Uploads all binaries and checksums to the release
+   - Uploads all binaries and checksums to the release (permanent storage)
-   - Uploads Docker images if available
 
 3. **Releases are available in**:
    - Repository Releases tab in Gitea
-   - Binaries ready for download
+   - All binaries ready for download
-   - Docker images (if Docker is available on runner)
+   - SHA256SUMS file for verification
+
+Note: Docker images are not built automatically. To build Docker images manually, use:
+```bash
+docker build -t nerd-monitor-server -f Dockerfile.server .
+docker build -t nerd-monitor-agent -f Dockerfile.agent .
+# Or use docker-compose: docker-compose build
+```
 
 ## Troubleshooting
 
 ### "docker: command not found" in workflow
-- Docker is not installed on your runner
+- Docker support is not required - the workflow builds binaries without it
-- This is **optional** - binaries will still build
+- Binary builds will always succeed
-- If you want Docker images, install Docker on the runner (see above)
+- Docker images must be built manually using: `docker build -f Dockerfile.server .`
-- The workflow will gracefully skip Docker builds and show a warning
+- See QUICKSTART.md or DOCKER_COMPOSE.md for manual Docker build instructions
 
 ### "Action not found" error
 - Make sure Gitea Actions is enabled
