+# Gitea Workflow Deployment to NAS
+
+This guide explains how to set up the Gitea workflow to deploy Kekbot to your NAS via SSH.
+
+## Prerequisites
+
+1. **Docker and Docker Compose** must be installed on your NAS
+2. **SSH access** enabled on your NAS with password authentication
+
+## Setup Instructions
+
+### 1. Add SSH Password Secret to Gitea
+
+1. Go to your Gitea repository
+2. Navigate to **Settings** → **Secrets** (or **Actions** → **Secrets**)
+3. Add a new secret named `NAS_SSH_PASSWORD`
+4. Set the value to your NAS user password (hllywluis)
+
+### 2. Verify NAS Configuration
+
+Ensure your NAS has:
+
+- Docker installed
+- Docker Compose installed
+- SSH server running on port 22
+- Password authentication enabled for SSH
+
+### 3. Test SSH Access (Optional)
+
+Before running the workflow, you can test SSH access:
+
+```bash
+ssh hllywluis@luis-nas.lan
+```
+
+## Workflow Configuration
+
+The workflow file is located at [`.gitea/workflows/deploy-nas.yml`](.gitea/workflows/deploy-nas.yml)
+
+### How It Works
+
+1. **Build**: Builds the Docker image locally using Docker Buildx
+2. **Save**: Saves the Docker image as a tar archive
+3. **Transfer**: Uses `sshpass` to SSH into your NAS and copy files
+4. **Deploy**: Loads the Docker image and runs `docker-compose up -d`
+
+### Manual Trigger
+
+You can manually trigger the deployment by:
+
+1. Going to your Gitea repository
+2. Navigating to **Actions**
+3. Selecting the **Deploy to NAS** workflow
+4. Clicking **Run workflow**
+
+## Troubleshooting
+
+### SSH Connection Failed
+
+If the workflow fails with SSH connection issues:
+
+- Verify `NAS_SSH_PASSWORD` secret is set correctly
+- Check that the NAS is reachable at `luis-nas.lan`
+- Ensure SSH password authentication is enabled on the NAS
+
+### Docker Errors
+
+If Docker fails on the NAS:
+
+- Verify Docker is running: `docker ps`
+- Check Docker Compose: `docker-compose --version`
+- Review logs: `docker-compose logs`
+
+### Permission Issues
+
+The workflow uses the `hllywluis` user. If you need a different user:
+
+1. Update the `hllywluis@luis-nas.lan` in the workflow file
+2. Adjust the `/mnt/kCloud/Home/hllywluis/kekbot` directory permissions accordingly
