 ### Common Issues
 
-1. **Runners not registering / Token appears empty**
-   - **Check if `.env.runners` file exists** in the project root
+1. **"Cannot find: node in PATH" or similar tool errors**
+   - **This is handled** by the official `gitea/act_runner:nightly` image which includes necessary tools
+   - **Environment variables** can be set in the configuration files to ensure proper tool paths
+   - **Check your configuration files** to ensure proper environment setup
+
+2. **"registration file not found, please register the runner first" error**
+   - **This is handled** by the official `gitea/act_runner:nightly` image with proper configuration
+   - **The `.runner` file** is created in the `/data` directory and persists between restarts
+   - **Ensure configuration files** are properly mounted and environment variables are set
+   - **Restart the runners** if you see this error:
+     ```bash
+     cd runners
+     docker-compose -f docker-compose.runners.yml down
+     docker-compose -f docker-compose.runners.yml up -d
+     ```
+
+3. **Configuration file not found errors**
+   - **Ensure all config files exist**: `config_heavy.yaml`, `config_light.yaml`, `config_docker.yaml`, `config_security.yaml`
+   - **Check file permissions** and ensure they're readable by the container
+   - **Verify volume mounts** in the Docker Compose file are correct
+
+4. **Runners not registering / Token appears empty**
+   - **Check if `.env.runners` file exists** in the `runners/` directory
    - **Verify the file contains your actual token** (not the placeholder)
    - **Make sure you're using the management scripts** (they include `--env-file` parameter)
    - **If running Docker Compose directly**, add `--env-file .env.runners`:
      ```bash
+     cd runners
      docker-compose -f docker-compose.runners.yml --env-file .env.runners up -d
      ```
 
-2. **Runners not registering**
+5. **Runners not registering**
    - Check Gitea instance URL and port
    - Verify runner token is correct
    - Ensure Gitea Actions is enabled
 
-3. **High resource usage**
+6. **High resource usage**
    - Adjust CPU/memory limits in docker-compose.runners.yml
    - Check for stuck jobs in Gitea Actions
 
-4. **Docker socket issues**
+7. **Docker socket issues**
    - Ensure Docker socket is accessible: `/var/run/docker.sock`
    - Check Docker daemon is running
 
-5. **Network connectivity**
+8. **Network connectivity**
    - Verify runners can reach Gitea instance
    - Check firewall settings
