## Footer content

```yaml
# Footer content 
# appears at the bottom of every page's main content
footer_content: "Copyright &copy; 2017-2019 Patrick Marsceill. Distributed by an <a href=\"https://github.com/pmarsceill/just-the-docs/tree/master/LICENSE.txt\">MIT license.</a>"

# Footer last edited timestamp
last_edit_timestamp: true # show or hide edit time - page must have `last_modified_date` defined in the frontmatter
last_edit_time_format: "%b %e %Y at %I:%M %p" # uses ruby's time format: https://ruby-doc.org/stdlib-2.7.0/libdoc/time/rdoc/Time.html

# Footer "Edit this page on GitHub" link text
gh_edit_link: true # show or hide edit this page link
gh_edit_link_text: "Edit this page on GitHub."
gh_edit_repository: "https://github.com/pmarsceill/just-the-docs" # the github URL for your repo
gh_edit_branch: "master" # the branch that your docs is served from
gh_edit_view_mode: "tree" # "tree" or "edit" if you want the user to jump into the editor immediately
```

- the "page last modified" data will only display if a page has a key called `last_modified_date`, formatted in some readable date format
- `last_edit_time_format` uses Ruby's DateTime formatter; see examples and more information [at this link.](https://apidock.com/ruby/DateTime/strftime)
- `gh_edit_repository` is the URL of the project's GitHub repository
- `gh_edit_branch` is the branch that the docs site is served from; defaults to `master`
- `gh_edit_view_mode` is `"tree"` by default, which brings the user to the github page; switch to `"edit"` to bring the user directly into editing mode

## Color scheme

```yaml
# Color scheme supports "light" (default) and "dark"
color_scheme: dark
```
<button class="btn js-toggle-dark-mode">Preview dark color scheme</button>

<script>
const toggleDarkMode = document.querySelector('.js-toggle-dark-mode');

jtd.addEvent(toggleDarkMode, 'click', function(){
  if (jtd.getTheme() === 'dark') {
    jtd.setTheme('light');
    toggleDarkMode.textContent = 'Preview dark color scheme';
  } else {
    jtd.setTheme('dark');
    toggleDarkMode.textContent = 'Return to the light side';
  }
});
</script>
