The distribution hasn't got a Changelog (named something like m/^chang(es?|log)|history$/i. A Changelog helps people decide if they want to upgrade to a new version.
Add a Changelog (best named 'Changes') to the distribution. It should list at least major changes implemented in newer versions.
|has proper version||
The version number isn't a number. It probably contains letter besides a leading 'v', which it shouldn't
Remove all letters from the version number. If you want to mark a release as a developer release, use the scheme 'Module-1.00_01'
|buildtool not executable||
The build tool (Build.PL/Makefile.PL) is executable. This is bad because you should specify which perl you want to use while installing.
Change the permissions of Build.PL/Makefile.PL to not-executable.
|has human readable license||
This distribution does not have a license defined in the documentation or in a file called LICENSE
Add a section called "LICENSE" to the documentation, or add a file named LICENSE to the distribution.
|has license in source file||
Does not have license information in any of its source files
Add =head1 LICENSE and the text of the license to the main module in your code.
|has abstract in pod||
No abstract (short description of a module) is found in pod from this distribution.
Provide a short description in the NAME section of the pod (after the module name followed by a hyphen) at least for the main module of this distribution.
|package version matches dist version||
None of the package versions in this distribution matches the distribution version.
Fix the version(s).
|meta yml declares perl version||
This distribution does not declare the minimum perl version in META.yml.
|meta yml has license||
This distribution does not have a license defined in META.yml.
Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.
|has known license in source file||
Does not have license information in any of its source files, or the information is not recognized by Software::License
Add =head1 LICENSE and/or the proper text of the well-known license to the main module in your code.
This distribution is not required by another distribution by another author.
Convince / force / bribe another CPAN author to use this distribution.
|no invalid versions||
This distribution has .pm files with an invalid version.
Fix the version numbers so that version::is_lax($version) returns true.
These fails are not serious and don't affect your Kwalitee scores at all.
|meta yml has provides||
This distribution does not have a list of provided modules defined in META.yml.
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.
|meta yml has repository resource||
This distribution does not have a link to a repository in META.yml.
Add a 'repository' resource to the META.yml via 'meta_add' accessor (for Module::Build) or META_ADD parameter (for ExtUtils::MakeMaker).
|has separate license file||
This distribution does not have a LICENSE or LICENCE file in its root directory.
This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
