# Flashing the YunoHost ISO
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** or an **SD card**.
### (Recommended) With Etcher
Download Etcher for your operating system and install it.
Plug your USB stick, select your YunoHost ISO and click "Flash"
### With UNetbootin
Download UNetbootin for your operating system and install it.
Put your USB stick on, select your YunoHost ISO and click "OK"
### With `dd`
If you are on Linux / Mac and know your way around command line, you may also
flash your USK stick or SD card with `dd`. You can identify which device corresponds to your
USB stick or SD card with `fdisk -l` or `lsblk`. An SD card name typically is something like `/dev/mmcblk0`. BE CAREFUL and make sure you got the right name.
Then run :
```bash
# Replace /dev/mmcblk0 if the name of your device is different...
dd if=/path/to/yunohost.img of=/dev/mmcblk0
```
### Burning a CD/DVD
For older devices, you might want to burn a CD/DVD. The software to use depends on your operating system.
* On Windows, use [ImgBurn](http://www.imgburn.com/) to write the image file on the disc
* On Mac OS, use [Disk Utility](http://support.apple.com/kb/ph7025)
* On GNU/Linux, you have plenty of choices, like [Brasero](https://wiki.gnome.org/Apps/Brasero) or [K3b](http://www.k3b.org/)
