+Run these commands to setup the dev env, which is a copy of the local repo as-is in a volume and a container attached to that volume:
+
+1. `docker build --tag mfbtech-react-async-renderer-dev-env .`
+1. `docker run --name mfbtech-react-async-renderer-dev-env -td mfbtech-react-async-renderer-dev-env`
+
+Now attach to the container using vscode and the remote explorer extension.
+
+>
+> Deleting the container will delete the volume as well, so make sure you have all of your work pushed before deleting the container.
