Hola! @akaifi has created a ZenHub account for the akaifi organization. ZenHub is the leading team collaboration and project management solution built for GitHub.

How do I use ZenHub?

To get set up with ZenHub, all you have to do is download the browser extension and log in with your GitHub account. Once you do, you’ll get access to ZenHub’s complete feature-set immediately.

What can ZenHub do?

ZenHub adds a series of enhancements directly inside the GitHub UI:

• Real-time, customizable task boards for GitHub issues;
• Burndown charts, estimates, and velocity tracking based on GitHub Milestones;
• Personal to-do lists and task prioritization;
• “+1” button for GitHub issues and comments;
• Drag-and-drop file sharing;
• Time-saving shortcuts like a quick repo switcher.

Add ZenHub to GitHub
