# Custom Fields Configuration

## Custom Fields Configuration

ActiveNow lets you collect the most relevant information about your clients and lessons.

In the *"Settings"* → *"General"* tab, under *"Custom fields settings"*, you have two ways to configure additional fields:

## Participant fields

These fields let you store permanent information about a participant — such as their ID number, home address, or any additional notes. You can also control who has access to them: you, the client, or the instructor.

You can read about the detailed configuration in this [article](/en/client-management/additional-information-in-participant-profile.md).

## E-register – lesson fields

If you track lesson topics, homework, or lesson plans, these fields help you keep that information organized. Once set up, they appear for every lesson. You can also control permissions — for example, you and the instructor can edit the data, while participants can only view it.

You can read about the detailed configuration in this [article](https://github.com/azyzio/activenow-help/blob/master/docs-en/instructor-panel/dodawanie-tematow-lekcji-lub-prac-domowych.md).
