+Apache Mesos is an effort undergoing incubation at the Apache Software 
+Foundation (ASF), sponsored by the 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.
+
+For more information about the incubation status of the Mesos project you
+can go to the following page:
