 ## Step-1. Prepare message sequences as seed inputs
 
-We have prepared a seed corpus to fuzz ippserver. If you want to create your own seed corpus, please follow the tutorial for fuzzing Live555 RTSP server included in the main AFLNet README.md.
+I'll follow the same steps as the live555 example to generate seed inputs from this capture. This involves opening the capture in wireshark and looking at the tcp stream. Then I export one side of the raw stream. 
-In this case we have 2 seed inputs, one for the print request and one for the cancel job.

 ## Step-2. Fuzzing
+Now on to fuzzing. Likewise for this exercise, I will use the supplied corpus input rather than my own gathered in step 1 to avoid the likelyhood of a mistake since this is a long running process
 
+The following commands from the readme will help
 ```bash
 cd $WORKDIR/ippsample/server
