 Show owners of one or more files in a repo.
 
+If C<--owner>, C<--project>, C<--pattern> are set, only show files with matching
+criteria. These can be repeated.
+
+Use C<--patterns> to also show the matching pattern associated with each file.
+
+By default the output might show associated projects if the C<CODEOWNERS> file
+defines them. You can control this by explicitly using C<--projects> or
+C<--no-projects> to always show or always hide defined projects, respectively.
