+name: Bug report
+about: Help us track down bugs in SCIP
+
+---
+
+Welcome to SCIP and thank you for reporting a bug!
+
+Please read the following before posting a new bug report:
+
+- If you have a question or are unsure if the behavior you're experiencing is expected, also feel free to reach out on the [mailing list](http://listserv.zib.de/mailman/listinfo/scip/).
+
+- If you are reasonably confident your issue is a bug in SCIP, this is the right place. Be sure to include as much relevant information as possible, including a minimal reproducible example. See https://help.github.com/articles/basic-writing-and-formatting-syntax/ for background on how to format text and code on GitHub issues.
+
+- If the issue occurs when running an instance, be sure to include it, along with any non-default setting.
+If the issue occurs with a model built programmatically, include a minimal script producing the model.
+You can use `SCIPwriteOrigProblem(scip, "my_model.lp", NULL, FALSE)` to write the model to a file.
+
+- If the problem is SCIP producing an incorrect solution, be sure to include a reference solution as a sol file, produced either by SCIP or another solver.
+You can also use `SCIPprintSol(scip, SCIPgetBestSol(scip), file, FALSE)` to print a solution to a file.
+
+Thanks for contributing to SCIP!

+### Description
+
+[Add a description of the introduced changes here.]
+
+### Code review
+
+* [ ] The code change is correct.
+* [ ] The naming and place of new methods is clear and consistent **or** no new methods have been added.
+* [ ] Emphasis settings are up to date.
+* [ ] Ensure that new code and features use randomization where necessary to account for performance variability.
+* [ ] The code is sufficiently documented.
+* [ ] The coding style is OK, see https://scipopt.org/doc/html/CODE.php.
+
+### Documentation and building
+
+* [ ] The CHANGELOG is up to date (including API changes if present in this MR).
+* [ ] The user documentation is up to date (doc/xternal.c, doc/inc/faq/, installation instructions, ...).
+* [ ] Both build systems and makedist.sh are up to date. Especially, newly added, renamed or removed source files have been added to, renamed in or removed from src/CMakeLists.txt.
+
+### Testing
+
+* [ ] ctest passes without errors.
+* [ ] The performance impact has been checked **or** the changed code will not be executed by default.
+* [ ] The new code is sufficiently covered by tests (perhaps, new coverage settings or new unit tests have been added).
+
+### Does this merge request introduce an API change? :warning:
+
+* [ ] No, **or** as far as possible, the code ensures backwards compatibility.
+* [ ] No, **or** the `SCIP_APIVERSION` is updated (use label 'public SCIP API'; in particular if new `SCIP_EXPORT` methods have been added).
+* [ ] No parameter was added/deleted/changed **or** the MR is tagged with the label 'default parameter'. (This includes the addition of parameters by adding/deleting a plugin.)
