-####Necessary Files
+#####1.2.2 Example Client
+The wolfSSL example client can be found in wolfssl/examples/client.
+1. Add client.c and client.h from the examples/client folder to the Workbench
+project.
+2. In usrAppInit.c, inlucde the func\_args as described in the Test Application
+section, and add a call to the client function:
+    client_test(&args);
+3. Add the client.h header file to the includes at the top of usrAppInit.c.
+4. The wolfSSLIP will need to be changed to the IP address the server is
+running on. If using the VxWorks Simulator, localhost will not work. NAT should
+be selected in the Simulator Connection Advanced setup.
+5. Start the example server from within the wolfSSL directory on the host
+machine:
+    ./examples/server/server -d -b
+The -d option disables peer checks, -b allows for binding to any interface.
+6. Start the example client in Workbench.
+
+#####1.2.3 Example Server
+The example server requires more configuration than the client if using the
+VxWorks simulator.
+1. Add server.c and server.h from the wolfssl/examples/server folder to the
+Workbench project.
+2. In usrAppInit.c, inlcude the func\args as described in the Test and Client
+applications and add a call to the server function:
+    server_test(&args);
+3. Add the server.h header file to the includes at the top of usrAppInit.c.
+4. Start the server by following the directions in Section 2 for setting up
+the VxWorks Simulator.
+5. Start the client on the host machine:
+    ./examples/client/client -d
+The -d option disables peer checks.
+Note: If there are certificate file errors, the file paths in wolfssl/test.h
+will need to be adjusted to follow the paths located on the filesystem used
+by the VxWorks project.

 To connect to a server running on the VxWorks Simulator, enter these commands
 into the host terminal (for Ubuntu 14.04):
     sudo openvpn --mktun --dev tap0
 In Wind River directory:
-    vxworks-7/host/x86-linux2/bin/vxsimnetd

 This will start the vxsimnetd application. Leave it open. The IP address to
 connect to the server is the same as above.
