Contributed libraries must be downloaded separately and placed within the "libraries" folder of your Processing sketchbook. To find the Processing sketchbook location on your computer, open the Preferences window from the Processing application and look for the "Sketchbook location" item at the top. Copy the contributed library's folder into the "libraries" folder at this location. <em>You will need to create the "libraries" folder if this is your first contributed library</em>. Follow the links below for more information about each library.<br />

<br />

Contributed libraries are developed, documented, and maintained by members of the Processing community. For feedback and support, please post to the <a href="http://processing.org/discourse">Discourse</a>, for development discussions post to <a href="http://processing.org/discourse/yabb_beta/YaBB.cgi?board=os_libraries_tools">Libraries, Tool Development</a>. Instructions for creating your own library are on the <a href="http://dev.processing.org/libraries/">Develop Processing</a> site.<br /><br />
