# Web Developer's Library 1.4

Welcome to the Web Developer's Library. This library is intended for Web developers creating widgets for S60 mobile devices that support Web Runtime (WRT) version 1.0 or 1.1.

Widgets are lightweight applications that are based on standard Web technologies and are typically used to access information on the Web. Widgets run in the WRT environment, which is supported by S60 3rd Edition, Feature Pack 2 and S60 5th Edition. On some S60 5th Edition devices, such as the Nokia N97, users can add widgets to the home screen.

You can access the latest version of Web Developer's Library from Forum Nokia.
