Hi
I have a question (may actually turn into more than one 
for a few months my Studio Code Server addon has said that my templates has an error. I am new to .yaml code (any coding language to be honest).
have tried to find a solution in various forums. I hope this is where i can ask for help.
I my configuration.yaml I have: template: !include template.yaml
and my template.yaml have been like this:
(Edit: included code, thanks @ [sparkydave])
