+### Run in GitHub Codespaces
+This repository also has devcontainers to allow it to run in GitHub codespaces. To use those:
+- Fork the repository to your account
+- In the "Code" button on the upper right of your browser, within the Codespaces tab click on the three dots and choose "New with Options", then you will have the choices:
+    - R Studio Server (the default useful for coding; you should set the RSTUDIO_PASSWORD with this option)
+    - Shiny apps for demos (useful for training or demoing)
+- To stop or delete your codespace when you are done: go to [GitHub Codespaces](https://github.com/codespaces)
