+
+> Converts Postman-SDK Request into code snippet for Dart dio.
+
+#### Prerequisites
+To run Code-Gen, ensure that you have NodeJS >= v12. A copy of the NodeJS installable can be downloaded from https://nodejs.org/en/download/package-manager.
+
+## Using the Module
+The module will expose an object which will have property `convert` which is the function for converting the Postman-SDK request to swift code snippet.
+
+### convert function
+Convert function takes three parameters
+
+* `request` - Postman-SDK Request Object
+
+* `options` - options is an object which hsa following properties
+    * `indentType` - String denoting type of indentation for code snippet. eg: 'Space', 'Tab'
+    * `indentCount` - The number of indentation characters to add per code level
+    * `trimRequestBody` - Whether or not request body fields should be trimmed
+
+* `callback` - callback function with first parameter as error and second parameter as string for code snippet
+
+##### Example:
+```js
+var request = new sdk.Request('www.google.com'),  //using postman sdk to create request  
+    options = {
+        indentCount: 3,
+        indentType: 'Space',
+        requestTimeout: 200,
+        trimRequestBody: true
+    };
+convert(request, options, function(error, snippet) {
+    if (error) {
+        //  handle error
+    }
+    //  handle snippet
+});
+```
+### Guidelines for using generated snippet
+
+* Since Postman-SDK Request object doesn't provide complete path of the file, it needs to be manually inserted in case of uploading a file.
+
+* This module doesn't support cookies.
