+# Intro
+
+This is PyPantograph, an machine-to-machine interaction interface for Lean 4.
+Its main purpose is to train and evaluate theorem proving agents. The main
+features are:
+1. Interfacing via the Python library, REPL, or C Library
+2. A mixture of expression-based and tactic-based proofs
+3. Pantograph has been designed with facilitating search in mind. A theorem
+   proving agent can simultaneously explore multiple branches of the proof.
+4. Handling of metavariable coupling
+5. Reading/Adding symbols from the environment
+6. Extraction of tactic training data
+7. Support for drafting
+
+## Design Rationale
+
+The Lean 4 interface is not conducive to search. Readers familiar with Coq may
+know that the Coq Serapi was superseded by CoqLSP. In the opinion of the
+authors, this is a mistake. An interface conducive for human operators to write
+proofs is often not an interface conductive to search.
+
+LeanDojo has architectural limitations that prevent it from gaining new features
+such as drafting without refactoring. Almost all of Pantograph's business logic
+is written in Lean, and Pantograph achieves tighter coupling between the data
+extraction and proof search components.
