# Most Important Variables

> Configure the minimum required variables for a self-hosted Tembo instance.

At minimum, set the following values in `/var/lib/tembo/config.json`. Replace `<your_ip_address>` with the IP address of your self-hosted instance.

```json theme={null}
{
  "api.base": "https://<your_ip_address>/api/",
  "api.agentApiUrl": "http://localhost:3001/api/",
  "frontend.url": "http://<your_ip_address>"
}
```

`api.base` must end with a trailing `/`. Merge these values into the existing configuration instead of replacing the entire file.

After saving the file, restart the API service:

```bash theme={null}
sudo systemctl restart tembo-ts-api
```
