# How to include the library
### Arduino Library Manager
First install Arduino IDE version 1.6.2 or newer, then simply use the Arduino Library Manager to install the library.
Please see the following page for instructions: <http://www.arduino.cc/en/Guide/Libraries#toc3>.
### Manual installation
First download the library by clicking on the following link: <https://github.com/felis/USB_Host_Shield_2.0/archive/master.zip>.
Then uncompress the zip folder and rename the directory to "USB\_Host\_Shield\_20", as any special characters are not supported by the Arduino IDE.
