LGTM! Only added a couple of small suggestions. Thank you 🙂

Only last comment is I wonder if we should have more emphasis on where to find the documentation, I wonder if it needs it's own section and a sentence saying 'check the website' sortof thing (rather than just at the bottom of the usage section)

we should have more emphasis on where to find the documentation

it's also at the bottom of the output section. Personally, I think it's ok as it is, but I don't mind another link (or maybe badge?).

I find reading the template diff awkward here, so I just generated a before- and after- from nf-core create. Attaching in case it's useful for others:

• Old: README.md
• New: README.md

Massive improvement, thanks @grst!

Made a few suggestions, let me know what you think.

[ewels]

Couple of very minor grammar changes, otherwise LGTM to merge.

Massive improvement - thank you @grst!
