+Apache NiFi 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 Apache NiFi project

+ that such additional attribution notices cannot be construed
+ as modifying the License.
+
+ You may add Your own copyright statement to Your modifications and

+- Build the nifi-parent module. Then you can go to the 'nifi-nar-maven-plugin'
+directory and follow its instructions and finally the 'nifi' directory. Building
+the nifi-parent and nifi-nar-maven-plugin should be rarely necessary as these
+will be released infrequently by comparison to the 'nifi' tree.
