Thank you for your interest in contributing to Verso. This document covers the mechanics of getting a change accepted.
Open an issue describing what you'd like to work on before sending a substantial pull request. This avoids duplicated effort and lets us confirm the change fits the framework's direction. Small fixes (typos, doc corrections, obvious bugs) can go straight to a pull request.
Verso accepts contributions under the Developer Certificate of Origin, version 1.1 (DCO). The DCO is a lightweight attestation that you wrote the contribution or otherwise have the right to submit it under the project's MIT license. There is no contributor license agreement to sign.
Every commit must carry a Signed-off-by line with your real name and email address:
Signed-off-by: Jane Developer <jane@example.com>
Git adds this for you when you commit with the -s flag:
git commit -s -m "Fix cell output formatting for nested data frames"If you forget the sign-off on a commit, you can amend it:
git commit --amend -s --no-editor sign off an entire branch:
git rebase --signoff mainBy signing off, you certify the following:

By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license

(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.

- Target the
mainbranch. - Keep each pull request focused on a single change.
- Include tests for behavior changes. Most of Verso's behavior, including command parsing, kernel execution, formatters, and the extension model, is covered by unit and integration tests that run without an editor or notebook host.
- Make sure the solution builds and the test suite passes before requesting review.
