## We recommend building with buildx: ##
## ##
## // Note: you can use the standard `docker build` command, but there is no multi-CPU architecture support ##
## ##
## // Create buildx instance ##
## docker buildx create --driver docker-container --name builder --bootstrap --use ##
## ##
## // Login to Rregistry ##
## docker login [REGSITRY_ADDRESS] ##
## ##
## // Build the docker image (both x86 and amd64 are supported) ##
## docker buildx build --platform=linux/amd64,linux/arm64 --push -t [REGSITRY_ADDRESS]/REGSITRY_USERNAME/gitignore.io . ##
