+## Supported OSs and Rust versions
+
+Linux, OSX and Windows are supported and tested via TravisCI and Appveyor.
+
+Rust stable is supported. Older versions of Rust are supported and tested via TravisCI. The minimum Rust version is
+incremented when it becomes inconvenient to support older versions. The current minimum version of Rust supported can
+be found in [.travis.yml](.travis.yml). If a version number is not specified in the `rust` section, only the named versions
+listed are supported. This should be stable, beta and nightly.
