Oh! I think this is gonna conflict with @dvdksn's PR; 🙈

• docs: editorial improvements, typo fixes #4712

@dvdksn can you help out, and see how to combine both? 🙈 ❤️

[dvdksn]

@thaJeztah no I think we are safe - they shouldn't be touching the same files

[thaJeztah]

Ah, that's great! I saw the kind of changes and though....oh no!

If you can help review; that'd be appreciated 🤗

[dvdksn]

left some comments, no big ones, and not all actionable (I plead guilty to thinking out loud)

[dvdksn]

LGTM, cc @thaJeztah

[dvdksn]

ah it needs to be squashed

[dvdksn]

LGTM, please squash

[thaJeztah]

I guess the emphasis on "running" here was to prevent it being confused for "The command allows you to run tasks".

This could be "In addition to tasks that are running" or something along those lines, but we can revisit that in a follow-up.

[thaJeztah]

LGTM

I'll do a quick squash
