Add in dependencies in package.json of docker image of node-red for adding new Node

Hello ,

How to add in dependencies in package.json of docker image of node-red?

For example i want to add a new nodes named Serial-In and Serial-Out.
For that i want to add ""node-red-node-serialport": "~0.10.2"" in dependencies in package.json.
How this is posible with docker node-red image?

Thanks

The docs for running node red in docker shows you how to do that.
