+In the [quickstart](@/documentation/quick-start/_index.md), you launched Aerogramme in "development mode", that do not require a configuration file. But for a real-world usage, you will need to specificy many things: how your users are managed, which port to use, how and where data is stored, etc.
+
+## A first configuration file
+
+Let's start with the following configuration file:
+
+```toml
+role = "Provider"
+pid = "aerogramme.pid"
+
+[imap]
+bind_addr = "[::]:1143"
+
+[lmtp]
+bind_addr = "[::1]:1025"
+hostname = "example.tld"
+
+[users]
+user_driver = "Static"
+user_list = "users.toml"
+```
+
+Copy this content in a file named `aerogramme.toml`.
+Also create an empty file named `users.toml` (Aerogramme does not know how to create it automatically yet).
+
+And then you can start Aerogramme with the following configuration file:
+
+```bash
+aerogramme -c aerogramme.toml provider daemon
+```

 because it is easier to run than a distributed real-world deployment. The goal here
 is that you get familiar with the software, you understand what it does and what it does not,
-so you can evaluate it. Once ready for a real deployment, you will find all the information you need in the cookbook.
