# Configuration

## How to set environment variables?

You can modify the `docker-compose.yml` file to override environment variables. Please do not forget to change in `main` and `worker` services of docker-compose since the following variables might be used in both.

## Environment Variables

:::warning
The default values for some environment variables might be different in our development setup but following table shows the default values for docker-compose setup, which is the recommended way to run the application.

:::danger
Please be careful with the `ENCRYPTION_KEY` environment variable. It is used to encrypt your credentials from third-party services. If you change it, you will not be able to access your connections and thus, your existing flows and connections will be useless.
