These instructions require that you have Docker properly setup on your Windows computer:
docker volume create portainer_data
docker run -d -p 3040:9000 --name portainer --restart=always -v portainer_data:/data portainer/portainer --no-auth -H tcp://host.docker.internal:2375
docker volume create --name=bitcoind-data
docker run -v bitcoind-data:/bitcoin --name=bitcoind-node -d -p 18444:18444 -p 127.0.0.1:18332:18332 bitcoindevelopernetwork/bitcoind-regtest
then, open Portainer on localhost:3040
then, open the console to write commmands
