That's one sentence; it's a good sentence, but it's not a lot. Nothing about running it.
And I already noted (in a very offhand way):
> the About section/link being there... it's offscreen by the start of the README, so I missed it
I think 10 years ago, that sidebar didn't exist on github, so I've got some old skimming habits I could modify... but I think the bar for READMEs should be higher. I was pleasantly surprised to see I wasn't alone in having too little info, though. This project is far far from being an outlier in this regards. 95% of ROS repos (robotics code packages) are worse :)
