 This is a API testing tool.
 
 ## Feature
-*  Response Body fields equation check
-*  Response Body [eval](https://expr.medv.io/)
-*  Output reference between TestCase
+* Response Body fields equation check  
+* Response Body [eval](https://expr.medv.io/)  
+* Output reference between TestCase  
 
 ## Template
 The following fields are templated with [sprig](http://masterminds.github.io/sprig/):
 
-*  API
-*  Request Body
+* API  
+* Request Body  
+
+## TODO
+* Reduce the size of context  
+* Support customized context  
 
 ## Limit
-*  Only support to parse the response body when it's a map
+* Only support to parse the response body when it's a map or array
