 ## Getting started
 
+You can navigate [to this webpage](https://mflowcode.github.io/documentation/md_getting-started.html) to get you get started using MFC on your local machine, cluster, or supercomputer!
+It's rather straightforward.
+Some examples are below.

 For a _very_ quick start, open a GitHub Codespace to load a pre-configured Docker container and familiarize yourself with MFC commands.
 Click <kbd> <> Code</kbd> (green button at top right) → <kbd>Codespaces</kbd> (right tab) → <kbd>+</kbd> (create a codespace).
 
+Alternatively, run MFC directly with Docker on your local machine:
+```bash
+docker run -it --rm --entrypoint bash sbryngelson/mfc:latest-cpu
+```
+Once inside the container, navigate to `/opt/MFC` to access MFC and run examples.
+
 > ****Note:**** Codespaces is a free service with a monthly quota of compute time and storage usage.
 > It is recommended for testing commands, troubleshooting, and running simple case files without installing dependencies or building MFC on your device.
 > Don't conduct any critical work here!
 > To learn more, please see [how Docker & Containers work](https://mflowcode.github.io/documentation/md_docker.html).
