+## Homework Assignment 3 Checklist
+
+1. [x] Add X3D-Edit as Netbeans Plugin from https://savage.nps.edu/X3D-Edit/#Downloads
+
+2. [x] Optional: checkout Open-DIS-Java library source from https://github.com/open-dis/open-dis-java
+
+3. [x] Otherwise just inspect files of interest from
+ [edu.nps.moves.examples](https://github.com/open-dis/open-dis-java/tree/master/src/main/java/edu/nps/moves/examples)
+
+4. [x] Copy README.md and create YournameREADME.md documentation file...
+
+5. [x] Plan a track of interest - entity travels in a circle and changes heading(orientation) correspondingly
+
+6. [x] Copy, then Refactor/Rename example file OpenDisEspduSender.java or OpenDisPduSender.java as YourNameSomething.java
+
+7. [x] Modify your example file to produce track PDUs (and be cool)
+
+8. [x] Generate PDUs...
+
+9. [x] Test PDU reading using Wireshark...example below (see also screenshot file)
+
+835 46.316530 172.20.155.227 172.20.159.255 DIS 186 PDUType: 1 Entity State, Platform, Land, (1:1:2)
