upgrading

[cthompstone]

Hi guys, there seems to be very little info about how to upgrade to a new version in the readme doc.
For those of us that are new to docker etc, can you add a few lines about how to upgrade.
Assuming we installed as shown in the readme, is the process?:

sudo docker stop signal-api
sudo docker rm signal-api
sudo docker run -d --name signal-api --restart=always -p 8080:8080 -v $HOME/.local/share/signal-cli:/home/.local/share/signal-cli -e 'MODE=json-rpc' bbernhard/signal-cli-rest-api

Or have I got this wrong or missed a step? Do I need to run:

sudo docker system prune -a

Thanks
