 # 1. Mission of HepLean
 
 The mission of HepLean is to digitalize results, meaning definitions, theorems and calculations, from physics into Lean 4 with an initial focus on high energy physics and in a way which is useful to the broad physics community.

 # 2. Vision of HepLean
 
 **Statement**: HepLean aspires to be the definitive formal repository for physics in Lean, akin to Mathlib for mathematics, with both the Lean and physics communities behind it and a potential formal collaboration.
