## 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:

877dev

Info

I am using IOTstack which works with Docker, you will need to change your node-modules directory as needed.

Preparation

Stop node-red container (I used Portainer CE)
Open linux terminal/Putty

Backup the originals:

cd /home/pi/IOTstack/volumes/nodered/data/node_modules/alexa-remote2
sudo mv alexa-remote.js alexa-remote.js.BAK
