 make-string converts all data types to string as JSON.toString. 
 
@@ -16,13 +16,22 @@ makeString(25); // '25'
 ## Why? ##
 I need to convert the object to string in configurable way like removing curly braces, with single quote, etc. So I created this module. If you face any issues with this module, Free feel to create the issues https://github.com/ajay2507/make-string/issues.
 
+## options ##
+Options can be passed as optional second param to makeString to configure few things.
+```json
+quotes: "single" | "double" | "no"(no quotes)  - "double"(default)
+braces: "true" | "false" - "true"(default)
+assignment: "=" (any assignment operator)
+```
 ## How to use ##
 
 ```js
 const makeString = require('make-string');
 makeString("make-string"); // "make-string"
 makeString("make-string", {quotes: 'single'}); // 'make-string'
+makeString("make-string", {quotes: 'no'}); // make-string
 makeString({package:"make-string"}); // '{"package":"make-string"}'
 makeString({package:"make-string"}, {braces: 'false'}); // '"package":"make-string"'
 makeString({package:"make-string"}, {assignment: '='}); // '{"package"="make-string"}'
+makeString({package:"make-string"}, {assignment: '=', quotes:'no'}); // '{package=make-string}'
 ```
