User Support
Start with documentation and examples
Search the user guide, FAQs, existing issues, and input tutorials before posting. If the problem remains, open a GitHub issue with enough information for another person to reproduce it.
Report a Bug
Make the report reproducible
- GUNDAM release tag or exact commit SHA;
- operating system, compiler, CMake, and ROOT versions;
- the smallest configuration and input that reproduce the behavior;
- the complete command and terminal output;
- expected behavior and observed behavior; and
- whether the issue occurs with a maintained tutorial input.
Request a Feature
Lead with the analysis need
Describe the scientific or technical workflow, why current functionality does not meet it, the expected user interface or configuration, and how the behavior could be validated. A clear use case makes design discussion more productive.
Contribute
Propose a focused pull request
Connect a pull request to a documented issue. Keep the change focused, use an appropriately named branch, and include tests, validation material, and documentation proportional to the change.
Before Posting
Protect data and credentials
Do not upload access tokens, passwords, private datasets, embargoed results, personal information, or experiment-restricted material to a public issue. Replace sensitive paths and values with safe placeholders while retaining enough structure to reproduce the problem.
