## One notebook, two entrances

This page is a **Markdown source file**. Open it from the portfolio or run
`/site/pages/markdown-demo/show.sh` in the terminal: both read the same published
text, images, GIF, and links.

### Keep the moving parts nearby

The small animation below is a local GIF. Put images and GIFs beside `index.md`,
then refer to their filenames. Copying this whole folder in a terminal session
keeps the notebook and its media together.

- Write headings, paragraphs, **bold**, *emphasis*, and `inline code`.
- Use ordinary Markdown images for photographs, drawings, and animated GIFs.
- Link to [About Trove](../about.txt) or open the [signal gallery manifest](../../galleries/signal/manifest.json).

### Edit once, publish together

```sh
nano /site/pages/markdown-demo/index.md
/site/pages/markdown-demo/show.sh
```

Session edits are temporary. For a lasting change, edit this source in
`content/pages/markdown-demo/`, rebuild the content, and export the guest seed.
The authoring guide in `content/README.md` gives the full workflow.

> A shared source keeps the website and a fresh terminal session in step.
