 Examine the tests for examples of how to use each rule.
 
+## Custom rules
+
+Iodine allows you to add your own custom validation rules through the `addRule` method. This method excepts two parameters. The first, is the name of the rule. The second, is the `closure` that Iodine should execute when calling the rule e.g.
+
+```js
+Iodine.addRule('lowerCase', (value) => value === value.toLowerCase());
+```
+
+**IMPORTANT**: Iodine will automatically make the first letter of the rule's name uppercase and prefix it with 'is'. You should therefore avoid adding the prefix yourself e.g.
+
+```js
+Iodine.addRule('lowerCase');   // correct
+Iodine.addRule('isLowerCase'); // wrong
+```
+
+If your rule needs to accept a parameter, simply include it in your `closure` as the second argument e.g.
+
+```js
+Iodine.addRule('equals', (value, param) => value == param);
+```
+
+You can also add error messages for your custom rules e.g.
+
+```js
+Iodine.addRule('equals', (value, param) => value == param);
+Iodine.setErrorMessages({ equals : `Value must be equal to '[PARAM]'` });
+```
+
 ## Contributing
 
 Thank you for considering a contribution to Iodine. You are welcome to submit a PR containing additional rules, however to be accepted, they must explain what they do, be useful to others, and include a suitable test to confirm they work correctly.
