# Collaborate on Issues

Sometimes an issue can define a simple task that can be done without any discussion or fuss. When you're working with issues that track different pieces of work that comprise a collective effort, issues can become a place where your team comes together to resolve a task or problem. This collaboration can involve several activities such as discussing the issue, updating progress, adding notes or comments, attaching related files, or updating the issue status.

The topics in this section of the documentation describe how to work with features in YouTrack that were built with collaboration in mind.
