Intro to Mantis



Intro to Trello





Writing bug reports that communicate an issue in a complete yet concise way can be a time-consuming process.

A good screenshot can communicate a lot that a written description can’t.

Even better is a screenshot that you’ve annotated with labels and arrows to guide whoever is going to be looking at your report in days, weeks, and even months to come.

Be sure to add screenshots whenever you can to your Mantis issue reports.

There are many excellent, free tools that let you:

  • capture part of a web page
  • capture an entire web page (!)
  • annotate the image
  • save the image to your computer or the cloud
