# This hook builds pixelplanet after a push, and deploys it
# If it is the production branch, it will deploy it on the life system, and other branch will get deployed to the dev-canvas (a second canvas that is running on the server)
# canvases.json, proxies.json and ecosystem.yml are already in the terget directories
# Update messages will get sent via the Webhooks to Discord
#
# To set up a server to use this, you have to go through the building steps manually first.
# This hook just builds the canvas, it does not install new packages if needed. So this has to be done manually first
