 ## Why Probe
-As TWGC performance work group, we found out that different block parameters, networks, chaicndoe language and chaincode logic having influence final TPS.
+As discussed with TWGC performance work group, we found out that different block parameters, networks, chaicndoe language and chaincode logic having influence final TPS.
+To answer, the best parameter for specific fabric network and fabric chaincode, I create this project.
 
 ### For Fabric user
-You are able to have better understanding with performance for your chaincode logic by:
+You are able to have better understanding with performance for specific chaincode logic by:
 1. Perpare probe for your test env.
 2. Start probe with parameters.
 3. Once ompleted, you will get the TPS rates with block parameters in GUI as above.
