This line:

You can get started with Handwrite here.

Points to a non-existent page.

It is also worth noting that builtree.github.io itself is broken too;
the link it has for Handwrite under /projects points to an unowned domain.

Hey, thanks for the report. All the links pointing to builtree have to be moved since we moved the project. I'll move it soon, the reference is: https://yashlamba.github.io/handwrite
