# Configuration
## Automatic
You can use an USB drive with HassOS to configure network options, SSH access to the host and to install updates.
Format a USB stick with FAT32/EXT4/NTFS and name it `CONFIG`. Alternative you can create a `CONFIG` folder inside boot partition. Use the following directory structure within the USB drive:
```
network/
modules/
udev/
authorized_keys
timesyncd.conf
hassos-xy.raucb
```
- The `network` folder can contain any kind of NetworkManager connection files. For more information see [Network][network.md].
- The `modules` folder is for modules-load configuration files.
- The `udev` folder is for udev rules files.
- The `authorized_keys` file activates debug SSH access on port `22222`. See [Debugging Hassio][debug-hassio].
- The `timesyncd.conf` file allow you to set different NTP servers. HassOS won't boot without correct working time servers!
- The `hassos-*.raucb` file is a firmware OTA update which will be installed. These can be found on on the [release][hassos-release] page.
You can put this USB stick into the device and it will be read on startup. You can also trigger this process later over the
API/UI or by calling `systemctl restart hassos-config` on the host.
## Local
### Bootargs
You can edit or create a `cmdline.txt` into your boot partition. That will be read from our bootloader.
### Kernel-Module
The kernel module folder `/etc/modules-load.d` is persistent and you can add your config files there. See [Systemd modules load][systemd-modules].
### Udev rules
The udev rules folder `/etc/udev/rules.d` is persistent and you can add your configuration files there.
### Network
You can manual add, edit or remove connections configs from `/etc/NetworkManager/system-connections`.
