Just one small nit, overall looks like a good start to build out the different sections.

We might also want to include the FAQ (https://projectcontour.io/resources/faq/) page to link to or merge together someway.

This looks great, thanks.

Ah, it looks like your most recent commit needs the signoff @johnnycase. Personally, I use git commit --amend -as to fix this sort of thing up, that will update the last commit to have the signed-off-by line. You'll need to git push --force afterwards too. Or, if you did that with the online edit, unfortunately you need to fix this by pulling, editing locally, and repushing. Sorry, this is a Github limitation.

It's actually better to do stuff locally rather than use the UI for this reason, sadly.

Once the CI passes and the DCO is sorted, I'll merge this for you.

i see, i'll make those edits and resubmit, thanks!

I pushed the changes, I also found the same edit mentioned by Steve should be applied to two other pages, so I included those as well. Let me know if anything else is needed.

Dang, it looks like the second commit here is still not signed off. In this case, it's okay, because I'm going to squash that one away anyway. Thanks very much!

[johnnycase]

Thanks for merging! Sorry about the commit not being signed off. The command I used was git commit -s -m "Message" should I add anything there?
