Installation

Download the pre-built packages of the latest release for Windows and MacOS; read the help page on how to install Coq with OPAM; or refer to the INSTALL file for the procedure to install from source.

Documentation

The sources of the documentation can be found in directory doc. The documentation of the last released version is available on the Coq web site at coq.inria.fr/documentation. See also Cocorico (the Coq wiki), and the Coq FAQ, for additional user-contributed documentation.

Changes

There is a file named CHANGES that explains the differences and the incompatibilities since last versions. If you upgrade Coq, please read it carefully.

The Coq Club

The Coq Club moderated mailing list is meant to be a standard way to discuss questions about the Coq system and related topics. The subscription link can be found at coq.inria.fr/community.

The topics to be discussed in the club should include:

  • technical problems;
  • questions about proof developments;
  • suggestions and questions about the implementation;
  • announcements of proofs;
  • theoretical questions about typed lambda-calculi which are closely related to Coq.

Bugs report

Please report any bug / feature request in our issue tracker.

To be effective, bug reports should mention the OCaml version used to compile and run Coq, the Coq version (coqtop -v), the configuration used, and include a complete source example leading to the bug.
