OK, so it's not actually a C# programme, it's just something for the

pulumi

command to read. And it needs AzureCLI installing So what about the yml files? Thre seems to be some information that's written in C# and some more information that's written in yml?

the

Pulumi.yaml

tells the Pulumi CLI some metadata about the project like the language runtime to use (as we support other languages) and a name and description for the project

if I

cd

to that location and

pulumi stack ls

then it says something about the other two yml files and gives URLs for

<http://app.pulumi.com|app.pulumi.com>

, so is the pulumi website involved in this somehow?

yes, state is stored in the pulumi service.

AFAIK it's an individual account, and the credentials have been passed to me

okay, you'll need to do

pulumi login

first and authenticate

that seems to somehow have been done already!

awesome, try running

pulumi preview

on one of the stacks once you've authenticated to Azure

So why wouldn't I just write a script for AzureCLI?
