The title on Github (and here) say "IBM Type."
But what is IBM Type? It's never explained. Instead the site leads off with an explanation of typography. Then it introduces a specific type. It never tells us what "IBM Type" encompasses or if it is a project, a group, a new thing, and old thing, a software package, a consulting service... etc... yes it says some revisions are coming, and it will be out of beta soon, but what is it?
This is again another project without a proper introduction. All too common on Github and other OSS sites.
That being said, the teaching examples on typography embedded in the document are great.
