# Install gcloud CLI (https://cloud.google.com/sdk/docs/quickstarts) and make sure that you have GCP admin permissions

# Open https://console.cloud.google.com/cloud-resource-manager to create a new GCP project if you do not have one available already. Make sure to enable billing for that project.

# The command that follows uses `-b` to run in the batch mode and it assumes that this is not the first time you create a cluster with `jx`.
# If that's not the case and this is indeed the first time you're creating a `jx` cluster, it will not have some of the default values like GitHub user and the installation might fail.
# Please remove `-b` from the command if this is NOT the first time you're creating a cluster with `jx`.
