Reporting Problems and Troubleshooting

Please report bugs, problems, and other issues with the tool at https://github.com/overturetool/overture/issues.

If you encounter a problem with the Overture IDE itself, please contact the Overture project and we will try to help. You can contact us at info@overturetool.org, or use StackOverflow — we monitor for questions using the vdm, vdm++, or vdmrt tags.

If you encounter a problem with a VDM specification, please try to make a small example that illustrates the problem before you contact us. If you are sure the bug is not already known in the GitHub issues list, you can create a new bug report.
