+<h2 id="provisional">Using a Provisional API Level</h2>
+
+<p>During an "Early Look" SDK release, the APIs may not be final, so the API Level integer
+will not be specified. You must instead use a provisional API Level in your application
+manifest in order to build applications against the Early Look platform. In this case,
+the provisional API Level is not an integer, but a string matching the codename of the
+unreleased platform version (for example, "Eclair"). The provisional API Level will be specified
+in the Early Look SDK release notes and is case-sensitive.</p>
+
+<p>The use of a provisional API Level is designed to protect developers 
+and device users from inadvertently publishing or installing applications based on the 
+Early Look framework API, which may not run properly on actual devices running the final
+system image.</p>
+
+<p>The provisional API Level will only be valid while using the Early Look SDK to run
+applications in the emulator. An application using the provisional API Level can never be 
+installed on an Android device. When the final SDK is released, you must replace any
+instances of the provisional API Level in your application manifest with the final 
+API Level integer.</p>
