## Overview

Chromebooks with Chrome OS run a Linux kernel. The only missing pieces to use them as full-featured Linux distro were gcc and make with their dependencies. Well, these pieces aren't missing anymore. Say hello to Chromebrew!

## Prerequisites

You will need a Chromebook with developer mode enabled. To do so, select your device on [the ChromiumOS Wiki](https://www.chromium.org/chromium-os/developer-information-for-chrome-os-devices) and follow the instructions listed there. Please be aware of the fact that developer mode is insecure if not properly configured.

Setting a password as instructed in the VT-2 login screen is recommended. It is also recommended to enable signed boot:

```bash
sudo chromeos-setdevpasswd
sudo crossystem dev_boot_signed_only=1
```

## Supported Systems

| Architecture | Supported? |
|:---:|:---:|
| x86_64 | Yes |
| i686 | Yes\* |
| armv7l | Yes |
| aarch64 | Yes |

\* _We can only provide limited support for i686 since Google has discontinued support. Although we can no longer support GUI apps, we will try to continue to support CLI programs._

## Installation

The beta, dev, and Canary channels are ***not*** supported and should ***not*** be used with Chromebrew. Failure to take notice of this warning will cause major issues with your Chromebrew installation.

See issue [#2890](https://github.com/chromebrew/chromebrew/issues/2890) and the [FAQ](https://github.com/chromebrew/chromebrew/wiki/FAQ) for more details.

Open the terminal with Ctrl+Alt+T and type `shell`. If this command returns `ERROR: unknown command: shell`, please have a second look at the prerequisites and make sure your Chromebook is in developer mode.

Then download and run the installation script below:

```bash
curl -Ls git.io/vddgY | bash
```

On a rooted Google OnHub, the command needs to be run with the "chronos" user. In order to make su work, a password is needed for the chronos user.

```bash
# passwd chronos
Changing password for chronos.
Enter new UNIX password:
Retype new UNIX password:
# su - chronos
Password:
$ curl -Ls git.io/vddgY | bash
```
