+=====
+*Disclaimer*
+
+Apache SkyWalking (incubating) is an effort undergoing incubation at The
+Apache Software Foundation (ASF), sponsored by the name of Apache
+Incubator PMC. 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.
