Hey Peter,

Well, in the App Settings you can find some information.  
And more about the coding and expressions in [[APP][Pro] Better Logic Library - For Users - Apps - Homey Community Forum](https://community.homey.app/t/app-pro-better-logic-library-for-users/71876/3).

The expressions are just basic JavaScript with it’s default buildin functions plus a few custom BLL functions.  
Coding can be used in supported textarguments and are just expressions within BLL “coding blocks”: `{[` expression `]}`.

And if you have any more questions, just post them here, and i or other people surely will help with answering them.

When i have time i intend to update the For Users topic with more tutorials, examples and explanations, based on the questions and answers here.
