+# Maestro MCP Docker Guide
+
+This guide explains how to build and run Maestro MCP using Docker.
+
+## Prerequisites
+
+- Docker installed on your system
+- Git repository cloned locally
+
+## Quick Start
+
+The easiest way to build and run Maestro MCP in Docker is to use the provided script:
+
+```bash
+./docker-build-run.sh
+```
+
+This script will:
+1. Build the Docker image
+2. Stop and remove any existing Maestro MCP container
+3. Start a new container with the appropriate settings
+4. Mount your local `config.yaml` into the container
+
+Once running, you can access Maestro MCP at: http://localhost:8030
+
+## Manual Docker Commands
+
+If you prefer to run the Docker commands manually:
+
+### Build the Docker image
+
+```bash
+docker build -t maestro-mcp:latest .
+```
+
+### Run the Docker container
+
+```bash
+docker run -d \
+ --name maestro-mcp \
+ -p 8030:8030 \
+ -v "$(pwd)/config.yaml:/app/config.yaml" \
+ maestro-mcp:latest
+```
+
+### Stop the container
+
+```bash
+docker stop maestro-mcp
+```
+
+### View container logs
+
+```bash
+docker logs maestro-mcp
+```
+
+## Configuration
+
+The Docker container uses the `config.yaml` file for configuration. By default, it mounts your local `config.yaml` file into the container.
+
+You can also override configuration settings using environment variables. For example:
+
+```bash
+docker run -d \
+ --name maestro-mcp \
+ -p 8030:8030 \
+ -e MAESTRO_MCP_SERVER_PORT=8030 \
+ -e MAESTRO_MCP_LOGGING_LEVEL=debug \
+ -v "$(pwd)/config.yaml:/app/config.yaml" \
+ maestro-mcp:latest
+```
+
+See the `.env.example` file for all available environment variables.
+
+## Customizing the Docker Image
+
+If you need to customize the Docker image, you can modify the `Dockerfile` and rebuild:
+
+1. Edit the `Dockerfile`
+2. Rebuild the image: `docker build -t maestro-mcp:custom .`
+3. Run with your custom image: `docker run -d --name maestro-mcp -p 8030:8030 maestro-mcp:custom`
+
+## Troubleshooting
+
+### Container fails to start
+
+Check the logs for errors:
+
+```bash
+docker logs maestro-mcp
+```
+
+### Port conflicts
+
+If port 8030 is already in use, you can map to a different port:
+
+```bash
+docker run -d --name maestro-mcp -p 8031:8030 maestro-mcp:latest
+```
+
+Then access Maestro MCP at http://localhost:8031
