 Paperproof will inspect how the hypotheses and goals were changing throughout the Lean 4 proof, and display this history - making it equivalent to how we think of a mathematical proof on paper.

+We created a few videos about Paperproof:
+- a super quick 1-minute demo of Paperproof: [youtube link](https://youtu.be/xiIQ0toSpxQ).

 In the following tables, you can see what tactics such as `apply`, `rw`, or `cases` look like in Paperproof; and how Paperproof renders real proofs from well-known repos.
