+
+This guide is essentially a beginner-friendly version of the [Getting Started](/react-native/docs/getting-started.html) page for React Native on Linux.
+
+### Prerequisites
+
+For the purposes of this guide, we assume that you're working on Ubuntu Linux 14.04 LTS.
+
+Before following this guide, you should have installed the Android SDK and run a successful Java-based "Hello World" app for Android.
+
+See [Android Setup](/react-native/docs/android-setup.html) for details.
+
+#### Installing NodeJS
+
+The first thing you need to do is to install NodeJS, a popular Javascript implementation.
+
+Fire up the Terminal and paste the following commands to install NodeJS from the [NodeSource](https://nodesource.com/) repository:
+
+```sh
+sudo apt-get install -y build-essential
+curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
+sudo apt-get install -y nodejs
+sudo ln -s /usr/bin/nodejs /usr/bin/node
+```
+__NOTE__: The above instructions are for Ubuntu. If you're on a different distro,  please follow the instructions on the [NodeJS website](https://nodejs.org/en/download/).
+
+#### Installing Watchman
+
+[watchman](https://facebook.github.io/watchman/docs/install.html) is a tool by Facebook for watching changes in the filesystem. You need to install it for better performance and avoid a node file-watching bug.
+
+Paste the following into your terminal to compile watchman from source and install it:
+
+```sh
+git clone https://github.com/facebook/watchman.git
+cd watchman
+git checkout v4.1.0  # the latest stable release
+./autogen.sh
+./configure
+make
+sudo make install
+```
+
+#### Installing Flow
+
+Flow is a static type checker for JavaScript. To install it, paste the following in the terminal:
+
+```sh
+sudo npm install -g flow-bin
+```
+
+## Setting up an Android Device
+
+Let's set up an Android device to run our starter project. 
+
+First thing is to plug in your device and check the manufacturer code by using `lsusb`, which should output something like this:
+
+```bash
+$ lsusb
+Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
+Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+Bus 001 Device 003: ID 22b8:2e76 Motorola PCS 
+Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
+Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
+Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+```
+These lines represent the USB devices currently connected to your machine.
+
+You want the line that represents your phone. If you're in doubt, try unplugging your phone and running the command again:
+
+```bash
+$ lsusb
+Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
+Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
+Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
+Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+```
+You'll see that after removing the phone, the line which has the phone model ("Motorola PCS" in this case) disappeared from the list. This is the line that we care about.
+
+`Bus 001 Device 003: ID 22b8:2e76 Motorola PCS`
+
+From the above line, you want to grab the first four digits from the device ID:
+
+`22b8:2e76` 
+
+In this case, it's `22b8`. That's the identifier for Motorola.
+
+You'll need to input this into your udev rules in order to get up and running:
+
+```sh
+echo SUBSYSTEM=="usb", ATTR{idVendor}=="22b8", MODE="0666", GROUP="plugdev" | sudo tee /etc/udev/rules.d/51-android-usb.rules
+```
+
+Make sure that you replace `22b8` with the identifier you get in the above command.
+
+Now check that your device is properly connecting to ADB, the Android Debug Bridge, by using `adb devices`.
+
+```bash
+List of devices attached
+TA9300GLMK	device
+```
+
+For more information, please see the docs for [running an Android app on your device](/react-native/docs/running-on-device-android.html).
+
+## Next Steps
+
+Your Android device and your tools are all ready to go. You can now follow the instructions in the [Quick Start](http://facebook.github.io/react-native/docs/getting-started.html#quick-start) guide to install React Native and start your first project.
