+    <description>
+      Selenium is a set of different software tools each with a different approach
+      to supporting browser automation. These tools are highly flexible, allowing
+      many options for locating and manipulating elements within a browser, and one
+      of its key features is the support for automating multiple browser platforms.
+      This package contains the .NET bindings for the concise and object-based
+      Selenium WebDriver API, which uses native OS-level events to manipulate the
+      browser, bypassing the JavaScript sandbox, and does not require the Selenium
+      Server to automate the browser.
