 var parser = require('xml2json');
 
 var xml = "<foo>bar</foo>";
-var json = parser.toJson(xml); //returns an string containing the json structure by default
+var json = parser.toJson(xml); //returns a string containing the JSON structure by default
 console.log(json);
 ```
+### Options
+
+* **object:** Returns a Javascript object instead of a JSON string
+* **reversible:** Makes the JSON reversible to XML (*)
+* **coerce:** Makes type coercion
+* **sanitize:** Sanitizes the following characters:
+
+| Character | Escaped |
+| --------- | ------- |
+|    `<`    |  `&lt;` |
+|    `>`    |  `&gt;` |
+|    `(`    |  `&#40;`|

+|           |         |
+
+* **trim:**
+
+```
+options = {
+        object: false,
+        reversible: false,
+        coerce: true,
+        sanitize: true,
+        trim: true };
+```
 * if you want to get the Javascript object then you might want to invoke parser.toJson(xml, {object: true});
 * if you want a reversible json to xml then you should use parser.toJson(xml, {reversible: true});
 * if you want to keep xml space text then you should use `options.space`, `parser.toJson(xml, {space: true})`;
