# 5. Functional configuration

### Before you start

* You must have first completed all the required steps in [Installation](https://documentation.opencrvs.org/v1.6/setup/3.-installation), particularly: 

[3.2-set-up-your-own-country-configuration](https://documentation.opencrvs.org/v1.6/setup/3.-installation/3.2-set-up-your-own-country-configuration "mention")

[3.3-set-up-a-server-hosted-environment](https://documentation.opencrvs.org/v1.6/setup/3.-installation/3.3-set-up-a-server-hosted-environment "mention")

1. Configure the application settings
2. Configure registration time periods and fees
3. Create system users
