+These libraries wrap standard Selenium client libraries to provide all the regular selenium commands dictated by the [jsonWire protocol](https://code.google.com/p/selenium/wiki/JsonWireProtocol), and add extra commands related to controlling mobile devices, such as **MultiTouch gestures** and **screen orientation**.
+
+Appium client libraries implement the [Mobile JsonWire Protocol](https://code.google.com/p/selenium/source/browse/spec-draft.md?repo=mobile), and the [W3C Webdriver spec](https://dvcs.w3.org/hg/webdriver/raw-file/default/webdriver-spec.html).
+
+Appium client libraries only **add** functionality, so they can still be used to run regular Selenium sessions.
