# Tips and Tricks

The WEM Modeler can be used to create any application you need. 

To achieve good results, it helps to first know how the Modeler works. And it helps even more if you can learn how to do certain things, how to model specific functionality, how to deal with lists, widgets, integration, etc. 

This section is dedicated to help you with all these things and more. Together with our WEM Partners we will keep adding new tips and tricks, and post updates on the [Forum](https://forum.wem.io) (*tip: subscribe there to receive updates in your e-mail*).
