# Numbus Server documentation ## ✏️ Filling the configuration file You can deploy the numbus-server without using a configuration file, **but I would strongly advise it** as it diminishes the risk of **typos** when providing credentials. It also creates a file that you can **keep**, **reuse**, **consult** whenever you are **in doubt** about a certain setting. > 🚀 Let's fill this configuration file ! The configuration file is divided into **multiple categories**. Some of them are **optional**, some are **mandatory**. Here is the list of categories : | Category | Available variables | | -------- | ------------------ | | [Live target settings](./live_target.md) | 2 | | [Server settings](/.server.md) | 7 | | [Mail settings](./mail.md) | 4 | | [Traefik settings](./automatic_ssl_certs.md) | 1 | | [Network settings](./network.md) | 3 | | [Services selection](./services/index.md) | 5 | | [Script settings](./script.md) | 1 |
