Hi @MarkEWaite and @StackScribe,

Here is my pull request for the missing pipeline help task. I am looking forward to your feedback. Thanks

[MarkEWaite]

@basil do you have permission to merge this pull request and #49 ? The SheCodeAfrica Contributhon is working during April to improve the Pipeline step descriptions, Pipeline argument descriptions, and Pipeline examples. We'd love to have fast review of their work

@basil do you have permission to merge this pull request and #49 ?

I do not; as far as I can tell, @dwnusbaum is the primary maintainer of the Pipeline plugins who merges PRs. Let me know if there's any way I can help.

I think the pattern of help documentation is to explain what the setting does, and then to state the default. Otherwise, this looks fine to me.

+1 to what @kwhetstone said. Also please add line break at the end of the file

@kwhetstone and @oleg-nenashev, thank you for the feedback. I have made changes.

Hi @MarkEWaite @kwhetstone, I have worked on your reviews. If there are no other improvements you want me to make, it would be amazing if you accept this PR and merge it. Thank you!
