 # DocTests
 
 _As of version 4.0.0, DocTests is no longer part of the "core" matlab-xunit and lives in its own repository at [matlab-xunit-doctests](https://github.com/psexton/matlab-xunit-doctests)._
+
+# Versioning
+
+This codebase is over 5 years old now, and has had several maintainers, so past versioning is kind of a mess. Starting with version 4.0.0, it follows [Semantic Versioning](http://semver.org) for versions, and [Semanticly Versioned Names](http://semvername.org) for tags and releases.
+
