# Flashing the YunoHost ISO on a USB stick or CD/DVD

Now that you downloaded the ISO image of YunoHost, you should flash/burn it on a physical medium. Typically, this is done on a **USB stick** but you might want to use a **CD/DVD** for older machines.

### With `dd`

If you know your way around command line, you may also flash your USB stick with
`dd`. Assuming your USB stick is `/dev/sdb` (be careful !!), you may run :

```bash
dd if=/path/to/yunohost.iso of=/dev/sdb
```
