 ## Supported Ruby Versions
 
 This library aims to support and is [tested against][travis] the following Ruby
 versions:
 
-* Ruby 2.2.x
+* Ruby 2.2.6+
 * Ruby 2.3.x
+* Ruby 2.4.x
 
+If something doesn't work on one of these versions, it's a bug.
 
+This library may inadvertently work (or seem to work) on other Ruby versions,
+however support will only be provided for the versions listed above.
+
+If you would like this library to support another Ruby version or
+implementation, you may volunteer to be a maintainer. Being a maintainer
+entails making sure all tests run and pass on that implementation. When
+something breaks on your implementation, you will be responsible for providing
+patches in a timely fashion. If critical issues for a particular implementation
+exist at the time of a major release, support for that Ruby version may be
+dropped.
+
