 There are some implementation details developers must consider:
 
 - JastAdd doesn't support `Map`. So, it must be constructed in a tuple (AST-Node). e.g.
-  - `ServerVariablesTuple ::= <Name> S:ServerVariableObject;`

 - In OAS, several objects can be replaced by [Reference Object](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#referenceObject). In `RAGO`, we implemented this structure in an abstract node to every concerned object. e.g.

-## Fuzzing Methods
+## Fuzzing in RAGO
+
+To generate API tests automatically, `RAGO` supports two following techniques based on Fuzzing, which involves  providing invalid, unexpected, or random data as inputs to an API.
+
+In this first version, this tool considers only two request types, `GET` and `POST`, and parameters. It means that `RAGO` currently generates only URLs.

+Random testing is based on the simple randomizer, `RandomRequestGenerator`. This generator reads an `OpenAPIObject` mapped by an OpenAPI documentation and checks all parameter types of operations existing in the `OpenAPIObject`.
+
+
+`RandomRequestGenerator` knows which request needs which parameter type and generates random parameters for all requests and URLs appending these parameters.
