+## Technical publishing with MyST
+
+MyST (Markedly Structured Text) is both:
+
+* A language, which extends Markdown, for authoring technical documents, including executable code cells, **and**
+* A software tool for rendering technical documents from MyST source
+
+
+## Using MyST in JupyterLab
+
+This JupyterLab instance has MyST installed, plus a special configuration for building
+and exposing a MyST site at a special URL.
+
+To preview a MyST site, first...
+
+::::::{info} Using MyST on your local machine
+:class: dropdown
+
+The special configuration for building and hosting our MyST site is not necessary on a
+local computer.
+We even have some special features that we can't use in the JupyterLab environment,
+for example a live-updating preview server:
+
+```bash
+myst start
+```
+
+:::{important} 👀 You should notice...
+:class: simple
+:icon: false
+
+...when the preview server successfully starts, the following message is printed:
+
+```
+🔌 Server started on port 3000!  🥳 🎉
+
+
+        👉  http://localhost:3000  👈
+```
+
+At this point, you can visit the printed URL to preview your site.
+The preview will automatically update any time you change a file.
