## 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.
