What happened

Expected behavior

Hi,

Thanks for the orb!

Don't know if this issue is connected to this line of the config or not:

my-pipeline: <<pipeline.number>>

But as someone who doesn't program CircleCI often, I think the documentation could benefit from a comment because I was wondering "how do I know my pipeline number?"

# you don't need to discover this value. Literally write the 'template' variable <<pipeline.number>>
my-pipeline: <<pipeline.number>>
