 # mCoq: Mutation Analysis for Coq
 
 mCoq is a tool for mutation analysis of verification projects that use the
-[Coq proof assistant](https://coq.inria.fr). mCoq applies a set of mutation
-operators to Coq definitions, with each application generating a modified
-version, called a mutant, of the project. If all proofs of a mutant are
-successfully checked, the mutant is declared live; otherwise it is declared
-killed. mCoq produces HTML reports pinpointing both live and killed mutants,
-where live mutants may indicate incomplete specifications. The
-[research paper][ase-paper] provides more information on the technique
-and optimizations that mCoq implements.

 our scripts for running the tool, so the steps shown in the paper submission
