 1. Create or use an existing ziti network with at least one edge router. This can be accomplished easily by running
-
-      ziti edge quickstart
+```
+ziti edge quickstart
+```
 
    after the quickstart runs, you'll have an ephemeral network usable for testing.
 
 1. Create at least two ziti identities and give them a common identity role i.e. #zping 
-
-      ziti edge create identity client -o client.jwt -a "zping"
-      ziti edge create identity server -o server.jwt -a "zping"
-      ziti edge enroll client.jwt
-      ziti edge enroll server.jwt
+```
+ziti edge create identity client -o client.jwt -a "zping"
+ziti edge create identity server -o server.jwt -a "zping"
+ziti edge enroll client.jwt
+ziti edge enroll server.jwt
+```
 
 1. Create a simple sdk service named "ziti-ping". This is the default service name `zping` looks for. You can 
    override the service by using the `-s` flag.
-
-      ziti edge create service ziti-ping
+```
+ziti edge create service ziti-ping
+```
 
 1. Create a bind policy with identityRoles set to [#zping] and serviceroles set to [@ziti-ping].
-
-      ziti edge create service-policy zping.bind Bind --identity-roles "#zping" --service-roles "@ziti-ping"
+```
+ziti edge create service-policy zping.bind Bind --identity-roles "#zping" --service-roles "@ziti-ping"
+```
 
 1. Create a dial service policy with identityRoles set to [#zping] and serviceroles set to [@ziti-ping].
-   
-      ziti edge create service-policy zping.dial Dial --identity-roles "#zping" --service-roles "@ziti-ping"
+```   
+ziti edge create service-policy zping.dial Dial --identity-roles "#zping" --service-roles "@ziti-ping"
+```
 
 1. Ensure that you have created appropriate edge-router and service-edge-router policies allowing the identities access
    edge-router(s) and the edge-routers access to the service. Verify by running policy-advisor. Both identities 
    should be able to dial **and** bind zping:
 
-      $ ziti edge policy-advisor identities -q
-      ERROR: Default Admin
-        - Identity does not have access to any services. Adjust service policies.
-   
-      OKAY : client (1) -> ziti-ping (1) Common Routers: (1/1) Dial: Y Bind: N
-      
-      OKAY : server (1) -> ziti-ping (1) Common Routers: (1/1) Dial: Y Bind: N
-      
-      ERROR: quickstart-router
-        - Identity does not have access to any services. Adjust service policies.
+```
+$ ziti edge policy-advisor identities -q
+ERROR: Default Admin
+  - Identity does not have access to any services. Adjust service policies.
+
+OKAY : client (1) -> ziti-ping (1) Common Routers: (1/1) Dial: Y Bind: N
+
+OKAY : server (1) -> ziti-ping (1) Common Routers: (1/1) Dial: Y Bind: N
+
+ERROR: quickstart-router
+  - Identity does not have access to any services. Adjust service policies.
+```
 
 1. In one window run the server
 ```
-    build/zping server -c server.json
+build/zping server -c server.json
+```
+
+example:
+```
+$ build/zping server -c server.json
+INFO[0000] binding service ziti-ping
+
+0xc00040d660 now serving
+
+INFO[0000] new service session                           session token=52e059d2-f166-4561-b5a4-b42056bcd787
+INFO[0041] new connection
 ```
-      example:
-      ```
-      $ build/zping server -c server.json
-      INFO[0000] binding service ziti-ping
-  
-      0xc00040d660 now serving
-  
-      INFO[0000] new service session                           session token=52e059d2-f166-4561-b5a4-b42056bcd787
-      INFO[0041] new connection
-      ```
 
 1. In another window run the client
 ```
-    build/zping client -c client.json -i server
-```
-      
-      ```
-       $ build/zping client -c client.json -i server

 1. Send 5 zpings from the client to the server using `-n 5`
 ```
