**Important:** to get it to work on GitHub Pages we need to add the following to the `Gemfile`:

```
group :jekyll_plugins do
  gem 'jekyll-commonmark-ghpages'
end
```

and modify your `_config.yml` to use **CommonMarkGhPages** as your Markdown converter:

```
markdown: CommonMarkGhPages
```

This processor is currently in testing for use in GitHub Pages.

To specify extensions and options for use in converting Markdown to HTML, supply options to the Markdown converter:

```
commonmark:
  options: ["SMART", "FOOTNOTES"]
  extensions: ["strikethrough", "autolink", "table", "tagfi
```

[CommonMark](https://commonmark.org/): One of our major goals is to [strongly specify Markdown](https://spec.commonmark.org/), and to eliminate the many old inconsistencies and ambiguities that made using Markdown so difficult.

**NOTE**: Unfortunately this brakes some of the latex and some html implementation in the blog. Maybe over Xmas.
