+
+I’ve recently added [#{repo}](https://github.com/CocoaPods/Specs/tree/master/#{repo}) to the [CocoaPods](https://github.com/CocoaPods/CocoaPods) package manager repo.
+
+CocoaPods is a tool for managing dependencies for OSX and iOS Xcode projects and provides a central repository for iOS/OSX libraries. This makes adding libraries to a project and updating them extremely easy and it will help users to resolve dependencies of the libraries they use.
+
+However, #{repo} doesn't have any version tags. I’ve added the current HEAD as version 0.0.1, but a version tag will make dependency resolution much easier.
+
+[Semantic version](http://semver.org) tags (instead of plain commit hashes/revisions) allow for [resolution of cross-dependencies](https://github.com/CocoaPods/Specs/wiki/Cross-dependencies-resolution-example).
+
+In case you didn’t know this yet; you can tag the current HEAD as, for instance, version 1.0.0, like so:
+
+```
+$ git tag -a 1.0.0 -m "Tag release 1.0.0"
+$ git push --tags
+```
+
+#{'――― TEMPLATE END ――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――'.reversed}
+
+#{'[!] This repo does not appear to have semantic version tags.'.yellow}
+
+After commiting the specification, consider opening a ticket with the template displayed above:
+  - link:  https://github.com/#{repo_id}/issues/new
+  - title: Please add semantic version tags
+EOS
+      end
     end
