Docker Compose instructions for adding new unsupported devices to Zigbee2mqtt

zigbee2mqtt-docker-compose-add-new-device

## Docker Compose

To setup a local copy of zigbee-herdsman-converters so that you can modify e.g. `devices.js` and from`Zigbee.js`; use the following instructions:

`cd /opt`
`git clone https://github.com/Koenkk/zigbee-herdsman-converters.git`


Now add the volumes to your `docker-compose.yml ` 
Example:
```
zigbee2mqtt:
    container_name: zigbee2mqtt
    image: koenkk/zigbee2mqtt:latest-dev
    volumes:
      - ./volumes/zigbee2mqtt/data:/app/data
      - /opt/zigbee-herdsman-converters/index.js:/app/node_modules/zigbee-herdsman-converters/index.js
      - /opt/zigbee-herdsman-converters/devices.js:/app/node_modules/zigbee-herdsman-converters/devices.js
      - /opt/zigbee-herdsman-converters/converters:/app/node_modules/zigbee-herdsman-converters/converters
      - /opt/zigbee-herdsman-converters/lib:/app/node_modules/zigbee-herdsman-converters/lib
    devices:
      #- /dev/ttyAMA0:/dev/ttyACM0
      - /dev/ttyACM0:/dev/ttyACM0
    restart: unless-stopped
    network_mode: host
```

To remove local changes simply remove/comment out the four `/opt/zigbee-herdsman-converters/......` lines from your docker-compose. 
Don't forget to run `docker-compose up -d ` after making changes to `docker-compose.yml`.
