+            <p>Apache AsterixDB is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored
+              by the Apache Incubator.
+              Incubation is required of all newly accepted projects until a further review indicates that the
+              infrastructure, communications, and decision making process have stabilized in a manner consistent with
+              other successful ASF projects.
+              While incubation status is not necessarily a reflection of the completeness or stability of the code, it
+              does indicate that the project has yet to be fully endorsed by the ASF.</p>
