+[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).
 
-            # Specify a list of frameworks that the application needs to link
-            # against for this Pod to work.
-            #
-            # s.framework = 'SomeFramework'
-            # s.frameworks = 'SomeFramework', 'AnotherFramework'
+In case you didn’t know this yet; you can tag the current HEAD as, for instance, version 1.0.0, like so:
 
-            # Specify a list of libraries that the application needs to link
-            # against for this Pod to work.
-            #
-            # s.library = 'iconv'
-            # s.libraries = 'iconv', 'xml2'
+```
+$ git tag -a 1.0.0 -m "Tag release 1.0.0"
+$ git push --tags
+```
 
-            # If this Pod uses ARC, specify it like so.
-            #
-            # s.requires_arc = true
