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: MIME::Body, MIME::Decoder, MIME::Decoder::Base64, MIME::Decoder::BinHex, MIME::Decoder::Binary, MIME::Decoder::Gzip64, MIME::Decoder::NBit, MIME::Decoder::QuotedPrint, MIME::Decoder::UU, MIME::Entity, MIME::Field::ConTraEnc, MIME::Field::ContDisp, MIME::Field::ContType, MIME::Field::ParamVal, MIME::Head, MIME::Parser, MIME::Parser::Filer, MIME::Parser::Reader, MIME::Parser::Results, MIME::Tools, MIME::WordDecoder, MIME::Words

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).
