Type Notes is a digital notebook on type design and production currently built and maintained by Matthew Smith. Over the years, I've been taking notes on what I've been learning in type design and Type Notes serves as an effort to consolidate and better articulate my learnings in one place.
At the moment, this is all stored in a private repository on GitHub. I actually haven't even made this public yet, so I'm a little surprised you've come across it. I will eventually be making it public and allowing people to contribute via submitting pull requests and issues on GitHub, but at the moment I just want to lay the foundation. So I politely ask that you keep this on the down low for now.
