Company-Coq is a new Emacs package that extends Proof General with a contextual auto-completion engine for Coq proofs and many additional facilities to make writing proofs easier and more efficient. Beyond fuzzy auto-completion of tactics, options, module names, and local definitions, company-coq offers offline in-editor documentation, convenient snippets, and multiple other Coq-specific IDE features. The system will be presented at CoqPL 2016, focusing on a live demo with an emphasis on writing proofs in Emacs more efficiently, and a discussion of desirable features of proof-oriented development environments. https://github.com/cpitclaudel/company-co
