SuperSlicer/.github/CONTRIBUTING.md

Did you encounter an issue with using Slic3r? Fear not! This guide will help you to write a good bug report in just a few, simple steps.

There is a good chance that the issue, you have encountered, is already reported. Please check the list of reported issues before creating a new issue report. If you find an existing issue report, feel free to add further information to that report.

If possible, please include the following information when reporting an issue:

• Slic3r version (See the about dialog for the version number. If running from git, please include the git commit ID from git rev-parse HEAD also.)
• Operating system type + version
• Steps to reproduce the issue, including:
  • Command line parameters used, if any
  • Slic3r configuration file (Use Export Config... from the File menu - please don't export a bundle)
  • Expected result
  • Actual result
  • Any error messages
• If the issue is related to G-code generation, please include the following:
  • STL, OBJ or AMF input file (please make sure the input file is not broken, e.g. non-manifold, before reporting a bug)
  • a screenshot of the G-code layer with the issue (e.g. using Pronterface)

Please make sure only to include one issue per report. If you encounter multiple, unrelated issues, please report them as such.

Simon Tatham has written an excellent on article on How to Report Bugs Effectively which is well worth reading, although it is not specific to Slic3r.
