# Setup #
#########

# This is a very big and complex demo and there is a strong
#   chance that I did not take into the account all the
#   permutations those trying it might have.
# Please let me know through a comment in the video or a direct
#   message in Twitter (@vfarcic) or Slack (Kubernetes or CNCF
#   workspaces) and I'll do my best to fix your issues and make
#   this demo more robust.

# Install `gum` by following the instructions in
#   https://github.com/charmbracelet/gum#installation
# Watch https://youtu.be/U8zCHA-9VLA if you are not familiar with Charm Gum
