 If you are looking for ways to specify the order in which the rules get applied on a fact, it can be done via using the `priority` parameter. Read more about it in the [Rule wiki](https://github.com/mithunsatheesh/node-rules/wiki/Rules). If you need to know about how to change priority of rules or remove add new rules to a Running Rule Engine, you may read more about it in [Dynamic Control Wiki](https://github.com/mithunsatheesh/node-rules/wiki/Dynamic-Control).
