Lingua-Shakespeare 1.00 Latest
Add a README to the distribution. It should contain a quick description of your module and how to install it.
Add a Changelog (best named 'Changes') to the distribution. It should list at least major changes implemented in newer versions.
Upgrade the bundled version of Module::Install to the most current release. Alternatively, you can switch to another build system / installer that does not suffer from this problem. (ExtUtils::MakeMaker, Module::Build both of which have their own set of problems.)
Add a META.json to the distribution. Your buildtool should be able to autogenerate it.
Add =head1 LICENSE and/or the proper text of the well-known license to the main module in your code.
Add 'use warnings' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.
Error: Lingua::Shakespeare, Lingua::Shakespeare::Character, Lingua::Shakespeare::Play
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.
