Just refining it up! Let's wait for Sam's review and the tweets to go up to merge this one!

Also, kinda (but maybe not that much) off-topic, we might need to think about a max number of notifications we want to have in the docs (that scrollbar is getting long!). I'm feeling like 3 is a good number, but maybe even less?! In that sense, should we remove the ones that are there pilling up below the container's fold?

3 makes sense to me. 👍

@danilo-leal Are we good to merge this PR?

[danilo-leal]

Not quite yet, I'd say! The notification is up at the moment we merge it, right? We should wait for the tweet—it'll be up today (Wednesday) or Thursday tops.

Yes, that's right.

Got it.
