GitHub Issue

Issues are a great way to keep track of tasks, enhancements, and bugs for your projects. They’re kind of like email - except they can be shared and discussed with the rest of your team. Most software projects have a bug tracker of some kind. GitHub’s tracker is called issues. 

The issue has its own section in every repository. GitHub’s issue tracking is special because of our focus on collaboration, references, and excellent text formatting.

Once you’ve collected a lot of issues, you may find it hard to find the ones you care about. Milestones, labels, and assignees are great features to filter and categorize issues.
