-# automatization
+# n8n and Temporal Docker Compose Setup
+
+This repository contains a Docker Compose configuration to run n8n and Temporal services together.
+
+## Services
+
+The setup includes:
+
+- **n8n**: An automation tool that allows you to create workflows visually
+- **Temporal**: A workflow orchestration platform with the following components:
+  - Temporal server
+  - Temporal UI
+  - PostgreSQL (database)
+  - Elasticsearch (for visibility features)
+
+## Custom Docker Images
+
+This project uses custom Docker images built from the following Dockerfiles:
+
+- **Dockerfile.n8n**: Extends the official n8n image with custom configurations
+- **Dockerfile.temporal**: Extends the official Temporal auto-setup image
+
+## Usage
+
+### Starting the services
+
+```bash
+docker compose up -d
+```
+
+This will start all services in detached mode.
+
+### Building custom images
+
+If you've made changes to the Dockerfiles, you'll need to rebuild the images:
+
+```bash
+docker compose build
+```
+
+Or to rebuild and start in one command:
+
+```bash
+docker compose down && docker compose build && docker compose up -d
+```
+
+### Verifying services are running
+
+Check that all containers are running:
+
+```bash
+docker compose ps
+```
+
+You should see containers for:
+- n8n
+- temporal
+- temporal-ui
+- temporal-postgresql
+- temporal-elasticsearch
+
+### Accessing the services
+
+- **n8n**: http://localhost:5678
+- **Temporal UI**: http://localhost:8080
+
+You can verify the services are responding with:
+
+```bash
+# Check n8n is responding
+curl -I http://localhost:5678
+
+# Check Temporal UI is responding
+curl -I http://localhost:8080
+```
+
+### Stopping the services
+
+```bash
+docker compose down
+```
+
+To completely remove all data volumes:
+
+```bash
+docker compose down -v
+```
+
+## Data Persistence
+
+All data is stored in local volumes under the `./volumes/` directory:
+
+- `./volumes/n8n_data` - n8n data and workflows
+- `./volumes/elasticsearch-data` - Elasticsearch data for Temporal
+- `./volumes/postgresql-data` - PostgreSQL database for Temporal
+
+## Service Ports
+
+- n8n: 5678
+- Temporal server: 7233 (gRPC API, not HTTP)
+- Temporal UI: 8080
+- PostgreSQL: 5432
+- Elasticsearch: 9200
+
+## Troubleshooting
+
+If you encounter any issues:
+
+1. Check container logs:
+   ```bash
+   docker logs temporal
+   docker logs automatization-n8n-1
+   ```
+
+2. Ensure all required ports are available on your system
+3. Make sure Docker has sufficient resources allocated
