 ## Compatibility
 
 This library is supported on Ruby 2.2 or later.
 
+However, Ruby 2.3 or later is strongly recommended, as earlier releases have
+reached or are nearing end-of-life. After June 1, 2018, Google will provide
+official support only for Ruby versions that are considered current and
+supported by Ruby Core (that is, Ruby versions that are either in normal
+maintenance or in security maintenance).
+See https://www.ruby-lang.org/en/downloads/branches/ for further details.
+
 This library follows [Semantic Versioning](http://semver.org/). It is currently
 in major version zero (0.y.z), which means that anything may change at any time
 and the public API should not be considered stable.
