# Microsoft Edge Demos

<!-- todo: maybe move "docs that use the demo" from tables (in Docs repo & Demos repo) to only the Readme in Demos repo -->

This repository contains demo webpages, apps, and sample code to demonstrate various features of Microsoft Edge.  This Readme lists all top-level source code directories.  Below, demos are grouped by major technology area, and then sorted by directory name within each section's table.

**Contents:**
* [Microsoft Edge DevTools](#microsoft-edge-devtools)
* [Microsoft Edge extensions](#microsoft-edge-extensions)
* [Progressive Web Apps (PWAs)](#progressive-web-apps-pwas)
* [Cross-browser API samples](#cross-browser-api-samples)
* [Adding a new demo](#adding-a-new-demo)
* [Contributing](#contributing)
* [Trademarks](#trademarks)
* [See also](#see-also)

<!-- table columns:
"Demo name": omit "demo"
"Description and docs": omit "PWA" unless ambig, omit "demo"
"Source code directory": sort on this col, to match dir order at https://github.com/MicrosoftEdge/Demos/
"Live demo page": adds "demo" if not present, for when headers are out of view

## Adding a new demo

To add a new demo:

1. Make a copy of the `/template/` directory at the root of this repository and give it a name, such as `/my-demo/`.

1. Edit the `README.md` file in the new directory to clearly explain what your new demo is about.

1. In the README file, include a GitHub.io link that points to the live demo.

   This repository is set up to be deployed live using GitHub Pages (GitHub.io), so a rendered `index.html` file in the `/my-demo/` directory (for example) will end up being accessible on the web at `https://microsoftedge.github.io/demos/my-demo/`.

1. Edit the code (such as `index.html` or `style.css`) in the new directory. Add any files you need.

1. Add a link to your demo in this `README.md` file, in a new row in one of the tables above, similar to the following row:

| Demo name | Description and docs | Source code & Readme | Live demo page |
|---|---|---|---|
| Template | Template directory to copy/paste to add a new demo.  Can be used for [Microsoft Edge Developer documentation](https://learn.microsoft.com/microsoft-edge/developer/). | [/template/](https://github.com/MicrosoftEdge/Demos/tree/main/template) | [My new demo](https://microsoftedge.github.io/Demos/template/) |
