+# Compatibility
+
+This file is the canonical resource for compatibility goals for the libraries that make up Sinon.JS.
+
+## ES5.1
+
+The source is written as [ES5.1][ES5] and requires no transpiler or polyfills.
+
+Sinon.JS uses feature detection to support [ES6][ES6] features, but does not rely on any of the new syntax introduced in [ES6][ES6] and remains compatible with [ES5.1][ES5] runtimes.
+
+## Runtimes
+
+Sinon.JS aims at supporting the following runtimes:
+
+* Firefox 45+
+* Chrome 48+
+* Internet Explorer 11+
+* Edge 14+
+* Safari 9+
+* Node LTS versions
