 The second and more common model is to load a general purpose sketch called StandardFirmata on the Arduino board and then use the host computer exclusively to interact with the Arduino board. StandardFirmata is located in the Arduino IDE in File -> Examples -> Firmata.
 
 ##Firmata Client Libraries

 ##Updating Firmata in the Arduino IDE - Arduino 1.6.4 and higher
 
 If you want to update to the latest stable version:
 
 1. Open the Arduino IDE and navigate to: `Sketch > Include Library > Manage Libraries`
 2. Filter by "Firmata" and click on the "Firmata by Firmata Developers" item in the list of results.
-3. Click the Select version dropdown and select the most recent version (not you can also install previous versions)

+###Cloning Firmata
 
 If you are contributing to Firmata or otherwise need a version newer than the latest tagged release, you can clone Firmata directly to your Arduino/libraries/ directory (where 3rd party libraries are installed). This only works for Arduino 1.6.4 and higher, for older versions you need to clone into the Arduino application directory (see section below titled "Using the Source code rather than release archive").
