 # nifiIoT
 
 Data Tracking using Apache nifi in IoT, IoE
+
+
+
+#Introduction
+Dockerfile to build a nifi container image
+
+#Version
+Current version: 0.0.1-SNAPSHOT - built from apache nifi commit 4d998c12c95a6e5ce3d66c0d861e75e33b5cf013
+
+#Quick Start
+Ensure that your host OS has protections in place such that the port is only open to machines you know about, e.g. with a firewall like iptables (open ports 8080 and 8081 for test purposes))
+
+You can launch the image using the docker command line
+
+docker run -d --name=nifi \
+-p 8080:8080 -p 8081:8081 \
+-v /tmp/output:/output \
+tkurc/nifi
+
+You can view the startup progress using docker logs command
+
+docker logs -f nifi
+
+Point your browser to http://localhost:8080/nifi
+
+The port 8081 is exposed, not for the application but for sampling the use of processors that will listen on ports (such as ListenHTTP). Likewise the `-v /tmp/output:/output' mounts the /tmp/output directory in the host to the data volume /output in the container, to sample the use of processors which can write to the local filesystem (PutFile).
