CONTRIBUTING.md

Contributing

Trixi.jl is an open-source project and we are very happy to accept contributions from the community. Please feel free to open issues or submit patches (preferably as pull requests) any time. For planned larger contributions, it is often beneficial to get in contact with one of the principal developers first (see AUTHORS.md).

Trixi.jl and its contributions are licensed under the MIT license (see LICENSE.md). As a contributor, you certify that all your contributions are in conformance with the Developer Certificate of Origin (Version 1.1), which is reproduced below.

LLM/AI usage

PRs which make use of LLMs and AI tools are allowed. However, because an LLM-assisted PR may have different issues than human-only PRs and necessitate different review styles, we request that PRs disclose any LLM contributions.

As before, all PRs are expected to be of high quality, and when possible, the developers will work with submitters to help achieve this. You are responsible for any code you submit, regardless of whether it was manually written or generated by AI. You should understand and explain the code you submit, as well as existing related code.

We encourage contributors to pre-check their PRs against our checklist, for example through manual review, using AI-based tools, or a combination of the two.
