+### Versioning
+
+For transparency into the release cycle and in striving to maintain backward compatibility, Esri Leaflet is maintained under the Semantic Versioning guidelines and will adhere to these rules whenever possible.
+
+Releases will be numbered with the following format:
+
+`<major>.<minor>.<patch>`
+
+And constructed with the following guidelines:
+
+* Breaking backward compatibility **bumps the major** while resetting minor and patch
+* New additions without breaking backward compatibility **bumps the minor** while resetting the patch
+* Bug fixes and misc changes **bumps only the patch**
+
+For more information on SemVer, please visit <http://semver.org/>.
