It's difficult to determine whether Redmine is rather a project management tool or an issue tracker. Issue tracking is not possible without a project (while some project management is still possible without issues). Even so, we spend most of our time working with Redmine as an issue tracker. This appears to be a fundamental component of Redmine that nevertheless depends on its other components. So, to use Redmine effectively, you have to learn it. For these reasons, we will start reviewing Redmine's functionality from its issue tracking capabilities.
In other words, the Issue tracking module is too deeply tied to other Redmine modules to be reviewed separately. But the opposite is also true—other modules use issues too extensively to skip issue tracking and start from reviewing other components. So, in this chapter, we will try to concentrate on issue tracking while also mentioning other modules if and where they are applicable. But don't worry if you are not familiar...
