# Install additional software

You can get a system for installing additional software by:

1. plugging in a partitioned, ext4 formatted USB device
2. enabling `Download Master` on that USB device

The `Download Master` installation mounts a subdirectory on the USB device to opt/bin and it fetches a bunch of packages including ipkg, the same tool that manages packages on OpenWRT.

## Entware

Entware is a [repository of prebuilt packages](https://bin.entware.net/aarch64-k3.10/Packages.html) that can be [installed on the USB device](https://github.com/Entware/Entware/wiki/Install-on-Asus-stock-firmware#deploying-entware).
```bash
wget -O - http://bin.entware.net/aarch64-k3.10/installer/generic.sh | sh
```
Using a standard init.d startup script system services can be launched on boot.
