+## Prerequisites
+
+- Docker installed on your system
+- Access to a Docker registry (optional)
+
+## Building the Docker Image
+
+To build the Docker image, navigate to the project directory and run the following command:
+
+```bash
+docker build -t de.captica.n8n .
+```
+This will build the Docker image using the Dockerfile in the current directory.
+
+## Running the Docker Container
+
+### To run the Docker container, use the following command
+
+```bash
+docker run -d -p 5678:5678 --name n8n de.captica.n8n
+```
+
+This will start a detached Docker container named "n8n" and expose port 5678 on your host machine. You can access n8n at http://localhost:5678 in your browser.
+
+### Customizing the Docker Image
+To customize the Docker image, you can modify the Dockerfile and rebuild the image. Here are some examples of customizations you might consider:
+1. Add custom workflows: Copy your workflows into the /data directory in the Dockerfile.
+2. Set environment variables: Use the ENV directive in the Dockerfile to set environment variables for n8n.
+3. Install additional packages: Use the RUN directive to install additional packages using apt-get or npm.
