+## Getting Started
+This project is configured to work with DevContainers/Codespaces to get developers up and running as quickly as possible. For DevContainers, all you need is [Docker][2] installed and you should be good to go! For Codespaces, you will need a GitHub account wiht Codespaces enabled.
+
+To see a full demo on how to setup your DevContainer/Codespaces environment, check out [this video][1] from @davidwesst where he walks through setting up HTBox/TwoWeeksReady, executing the various development tasks, and provides an overview about DevContainers and Codespaces.
+
+To setup your own development environment from scratch or to install the dependendies locally, refer to the files [`.devcontainer/devcontainer.json`](https://github.com/HTBox/TwoWeeksReady/blob/main/.devcontainer/devcontainer.json) and [`.devcontainer/Dockerfile`](https://github.com/HTBox/TwoWeeksReady/blob/main/.devcontainer/devcontainer.json) to understand what tools are required.
