Also removed empty page + minor update to paragraph spacing.

I think overall it's moving in the right direction.

I'm just wondering if we should separate the flow in some way, rather than try to combine them all.

E.g. if one is interested in Redux, then join these channels, pick a help wanted ticket here, set up your machine, etc.

[jwilander]

Yeah I was thinking about that as well, but I do think there is a good chunk that would be shared between all of them

We can probably re-org the whole thing a bit to make it work with having some info here and specific info in the other sections

Should I create a separate ticket for it?

[jwilander]

@jasonblais yes please, that way this PR won't go stale and we can merge it

Thanks, I meant to come back to this and review.

Made a couple of minor tweaks 00d1617
