+Apache AGE is an effort undergoing incubation at
+The Apache Software Foundation (ASF), sponsored by 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.
