 <h4>Welcome to the Software Heritage archive</h4>

 <h4>Overview</h4>
 
 <p>
   The long term goal of the Software Heritage initiative is to <strong>collect</strong>
   all publicly available software in source code form together with its
   development history, replicate it massively to ensure its <strong>preservation</strong>,
   and <strong>share</strong> it with everyone who needs it.
 
   The Software Heritage archive is growing over time as we crawl new source code from software
   projects and development forges.

 <h4>Content</h4>
 
 <p>
   A significant amount of source code has already been ingested in the Software Heritage
   archive. It currently includes:

 <iframe class="swh-coverage-list" src="{% url 'swh-coverage' %}"></iframe>
 
 <h4>Size</h4>
