+### Test
+
+You can run a simple test collection using nfcapd from the nfdump package with the following.
+
+- Start a netflow collector
+
+```
+sudo apt-get install nfdump
+mkdir /tmp/nfcap-test
+nfcapd -E  -p 9001 -l /tmp/nfcap-test
+```
+
+In a seperate console, run the netflow-generator pointing at an IP on the host the collector is running on (in this case the VM has an IP of 192.168.1.113).
+
+```
+sudo docker run -it --rm networkstatic/nflow-generator -t 192.168.1.113 -p 9001
+```
+
+- You should start seeing records displayed to the output of the screen running nfcapd like the following.

+```
+$> nfcapd -E  -p 9001 -l /tmp/nfcap-test
