# Netbird server {#module-services-netbird-server}
NetBird is a VPN built on top of WireGuard® making it easy to create secure private networks for your organization or home.
## Quickstart {#module-services-netbird-server-quickstart}
To fully setup Netbird as a self-hosted server, we need both a Coturn server and an identity provider, the list of supported SSOs and their setup are available [on Netbird's documentation](https://docs.netbird.io/selfhosted/selfhosted-guide#step-3-configure-identity-provider-idp).
There are quite a few settings that need to be passed to Netbird for it to function, and a minimal config looks like :
```nix
services.netbird.server = {
enable = true;
domain = "netbird.example.selfhosted";
enableNginx = true;
coturn = {
enable = true;
passwordFile = "/path/to/a/secret/password";
};
management = {
oidcConfigEndpoint = "https://sso.example.selfhosted/oauth2/openid/netbird/.well-known/openid-configuration";
settings = {
TURNConfig = {
Turns = [
{
Proto = "udp";
URI = "turn:netbird.example.selfhosted:3478";
Username = "netbird";
Password._secret = "/path/to/a/secret/password";
}
];
};
};
};
};
```
