 ## Ubuntu
 
-Hello Robot utilizes Ubuntu, an open source Linux operating system, for the Stretch RE1 platform. If you are unfamiliar with the operating system, we encourage you to review a [tutorial](https://ubuntu.com/tutorials/command-line-for-beginners#1-overview) provided by Ubuntu. Additionally, the Linux command line, BASH, is used to execute commands and is needed to run ROS on the Stretch robot. Here is a [tutorial](https://ryanstutorials.net/linuxtutorial/) on getting started with BASH.

-If a you are unable to dual boot and install ubuntu on your local machine, an alternative is to use [AWS RoboMaker](https://aws.amazon.com/robomaker/). AWS RoboMaker extends the ROS framework with cloud services. The service provides a robotics simulation service, allowing for testing of the Stretch RE1 platform. If you are a first-time user of AWS RoboMaker, follow the [guide here](https://github.com/aws-robotics/aws-robomaker-robotics-curriculum/blob/main/getting-started-with-aws-robomaker/_modules/mod-2a-aws.md) to get up and running with the service.
