Add a META.json to the distribution. Your buildtool should be able to autogenerate it.

Fix MANIFEST (or MANIFEST.SKIP) to exclude dot directories from a distribution. Use an appropriate tool and avoid archiving your working directory by hand. If you switch your version control system, remove old VCS directories after you migrate.

Error: .git

Add all modules contained in this distribution to the META.yml field 'provides'. Module::Build or Dist::Zilla::Plugin::MetaProvides do this automatically for you.

Add a 'repository' resource to the META.yml via 'meta_add' accessor (for Module::Build) or META_ADD parameter (for ExtUtils::MakeMaker).

This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
