+# AyrisTech Mail Worker (V10.3) - English
+
+Service that monitors Mailcow Dovecot logs and filesystem to forward new incoming emails to a Next.js webhook.
+
+## Installation
+
+### 1. Prepare Files
+Go to the project directory and edit the `.env` file (refer to `.env.example`):
+```env
+NEXTJS_WEBHOOK_URL=https://your-domain.com/api/webhooks/mail-signal
+WEBHOOK_SECRET=your_strong_secret_here
+```
+
+### 2. Run Locally
+Ensure Node.js (v18+) is installed:
+```bash
+npm install
+npm start
+```
+
+### 3. Run with Docker
+The most secure and easy method is to run as a Docker container:
+
+```bash
+# Build the image
+docker build -t ayristech-worker .
+
+# Start the container
+docker run -d \
+  --name ayristech-worker \
+  -v /var/run/docker.sock:/var/run/docker.sock \
+  -v /var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/:/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/ \
+  --env-file .env \
+  --restart unless-stopped \
+  ayristech-worker
+```
+
+## Important Notes
+- **Docker Socket**: The service uses the `docker exec` command, so `/var/run/docker.sock` must be mounted.
+- **Vmail Volume**: The volume where Mailcow stores email files must be mounted to the path `/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/`.
