Comment forms allow some HTML, this plugin extends that to let users type in <a href="http://daringfireball.net/projects/markdown/" rel="nofollow ugc">Markdown</a> and have it automatically converted to HTML. It also extends Markdown with a couple features made popular <a href="https://github.com/github/github-flavored-markdown" rel="nofollow ugc">by GitHub</a>. Conversion from Markdown to HTML is completely automated and doesn’t require anything on the commenter’s part.
The feature additions from GitHub are:
<ul>
<li>Single linebreaks are treated as new paragraphs</li>
<li>Code “fencing” with three backticks (“`)</li>
</ul>
Two notable features from GitHub’s Markdown implementation are missing:
<ul>
<li>To do lists: Doing these well would require some front end interaction, which I decided is outside the scope of this plugin at least for now</li>
<li>Repository autolinking (e.g. comments, issues, etc): These seemed a little too GitHub-specific.</li>
</ul>
GitHub-Flavored Markdown Comments is developed, unsurprisingly, <a href="https://github.com/evansolomon/wp-github-flavored-markdown-comments" rel="nofollow ugc">on GitHub</a>.

<a href="https://ivanrf.com/en/github-release-downloads/" rel="nofollow ugc">GitHub Release Downloads</a> allows you to get the download count, links and more information for releases of GitHub repositories.
<h4>Download count</h4>
The shortcode is <code>[grd_count]</code>. It returns a number corresponding to the sum of all download count values for the selected releases. For instance, you can get the number of total downloads for one GitHub repository.
Attributes
<ul>
<li><code>user</code>: the GitHub username.</li>
<li><code>repo</code>: the GitHub repository name.</li>
<li><code>latest</code>: only gets information about the latest published release for the repository.</li>
<li><code>tag</code>: only gets information about the release with the specified tag name.</li>
<li><code>prereleases</code>: includes draft releases and prereleases. Default value is <code>false</code>.</li>
</ul>
Examples
<ul>
<li>All repository downloads: <code>[grd_count user="IvanRF" repo="MassiveFileRenamer"]</code></li>
<li>Latest release downloads: <code>[grd_count user="IvanRF" repo="MassiveFileRenamer" latest="true"]</code></li>
<li>Specific release downloads: <code>[grd_count user="IvanRF" repo="MassiveFileRenamer" tag="v1.6.0"]</code></li>
</ul>
Note: <code>user</code> and/or <code>repo</code> can be omitted if default values are set.
<h4>Release downloads list</h4>
The shortcode is <code>[grd_list]</code>. It returns an HTML list for the selected releases including the release tag name, the release description and the list of files that can be downloaded, like release assets or the source code. 
For styling, class selectors are provided (e.g.: <code>release-downloads-header</code>, <code>release-name</code>, etc.).
Attributes
<ul>
<li><code>user</code>, <code>repo</code>, <code>latest</code>, <code>tag</code>, <code>prereleases</code>: same as above.</li>
<li><code>hide_description</code>: hides the release description.</li>
<li><code>hide_size</code>: hides information about the file size.</li>
<li><code>hide_downloads</code>: hides information about the download count.</li>
<li><code>downloads_suffix</code>: use it for internationalization. Default value is <code>" downloads"</code>.</li>
<li><code>hide_source_code</code>: hides the download link for the source code.</li>
</ul>
Examples
<ul>
<li>All repository downloads: <code>[grd_list user="IvanRF" repo="MassiveFileRenamer"]</code></li>
<li>Latest release downloads: <code>[grd_list user="IvanRF" repo="MassiveFileRenamer" latest="true"]</code></li>
<li>Specific release downloads: <code>[grd_list user="IvanRF" repo="MassiveFileRenamer" tag="v1.5.6"]</code></li>
<li>Hide file size: <code>[grd_list user="IvanRF" repo="MassiveFileRenamer" hide_size="true"]</code></li>
<li>Hide downloads count: <code>[grd_list user="IvanRF" repo="MassiveFileRenamer" hide_downloads="true"]</code></li>
<li>Downloads suffix change: <code>[grd_list user="IvanRF" repo="MassiveFileRenamer" downloads_suffix="descargas"]</code></li>
</ul>
Boolean attributes can take any of this values: “1”, “true”, “on” and “yes”; or “0”, “false”, “off” and “no”.
<h4>Latest version</h4>
The shortcode is <code>[grd_latest_version]</code>. It returns the tag name of the latest published full release. 
For tag names like “v1.6.0”, it returns “1.6.0” as the version number.
Attributes
<ul>
<li><code>user</code>, <code>repo</code>, <code>prereleases</code>: same as above.</li>
</ul>
<h4>Settings</h4>
Under WordPress Settings menu you will find the GitHub Release Downloads options page. In this page you can set values for the GitHub username and the repository name to use by default in the shortcodes.
If both values are set, the shortcodes can be used without attributes (e.g.: <code>[grd_count]</code>) since default values for <code>user</code> and <code>repo</code> will be used. 
Attribute values take precedence over default values. For example, <code>[grd_count repo="MyRepo"]</code> will use the username default value and the repository specified in the shortcode.
