One solution:
setup a basic _index.md
now you have two choices the only thing you need is the exchange the Your_git_handle_here with your own git username.
First the simple version:
<!-- Alignment options!!!!! -->
<div align="center">
<img width="600" height="300" src="https://ghchart.rshah.org/409ba5/Your_git_handle_here">
</div>
This will give you a blue version - you can change it as you like. Change this → /409ba5/
The second option also provides additional information such as longest streak etc.
add the following to your _index.md
or other .md
<!-- Include the library. -->
<script
src="https://unpkg.com/github-calendar@latest/dist/github-calendar.min.js">
</script>
<!-- Optionally, include the theme (if you don't want to struggle to write the CSS) -->
<link
rel="stylesheet"
href="https://unpkg.com/github-calendar@latest/dist/github-calendar-responsive.css"
/>
<!-- Prepare a container for your calendar. -->
<div class="calendar">
<!-- Loading stuff -->
Loading the data just for you.
</div>
<script>
// or enable responsive functionality:
GitHubCalendar(".calendar", "Your_git_handle_here", { responsive: true },{ tooltips: true });
</script>
