This is not a standalone theme. It is a Hugo theme component providing a shortcode: github-calendar to display github-calendar.js in your Hugo site.

Contrary to other shortcodes, this shortcode uses locally sourced JS and CSS so they must be included. Changes made from the upstream source files were:

• github-calendar.min.js: reducing the width of the graph inside its container for better looks (upstream the text is too close to the left border of its container)
• github-calendar.css: introducing root variables for background and text color to make them conveniently configurable via the shortcode

1. Add the hugo-github-calendar as a submodule to be able to get upstream changes later git submodule add https://github.com/totoroot/hugo-github-calendar.git themes/hugo-github-calendar

2. Add hugo-github-calendar as the left-most element of the theme list variable in your site's or theme's configuration file config.yaml or config.toml. Example, with config.yaml:

   theme: ["hugo-github-calendar", "my-theme"]

   or, with config.toml,

   theme = ["hugo-github-calendar", "my-theme"]

3. In your site, use the shortcode, this way:

   {{< github-calendar username="totoroot" >}}{{</ github-calendar >}}

   Just replace my username with yours. The shortcode expects at least the username, but accepts some optional variable as well.

   All options that can be passed via shortcode, are listed below:

   {{< github-calendar username="totoroot" responsive=true width=100 backgroundColor=#303030 textColor=#ececec >}}{{</ github-calendar >}}

   Name	Type	Default	Description
   username	string	totoroot	The username used to fetch GitHub contributions.
   responsive	bool	true	If graph should be sized responsively in relation to its container.
   width	integer	100	The width of the graph's container in percent.
   backgroundColor	CSS color value	#303030	The color value to use for the background of the container.
   textColor	CSS color value	#ececec	The color value to use for all text in the container.
