 You can run this project via dev containers.  First you will need to ensure that you have the [VSCode dev containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers)
 
 Once you have the extension installed, there are a couple ways to get started.  From this directory run `code .` to open a new VSCode window targeting this directory.  After a few seconds you should get a notification in the bottom right asking if you want to reopen the workspace in a container.  This will open a new VScode window and will start the process of building and running all of the containers.

-Another method is to open the `Command Pallete` (CMD+Shift+P) and search for `Dev Containers: Open Folder in Dev Container`.  Select this folder and VScode will open a new window and kick off the process.  The very first time you do this it will take several minutes to build the images and start the containers.

 Alternatively, you can also just use the compose files to start a stack and connect your VSCode instance to the backend container.
 
 To do that, clone the repo and `cd` into this directory.
