+# Contributing
+
+We welcome contributions from the community. Please read the following guidelines carefully to maximize the chances of your PR being merged.
+
+## Coding Style
+
+- To ensure your change passes format checks, run `make check`. To format your files, you can run `make format`.
+- We follow standard Go table-driven tests and use an internal [testing library](./internal/testing/require) to assert correctness. To verify all tests pass, you can run `make test`.
+
+## DCO
+
+We require DCO signoff line in every commit to this repo.
+
+The sign-off is a simple line at the end of the explanation for the
+patch, which certifies that you wrote it or otherwise have the right to
+pass it on as an open-source patch. The rules are pretty simple: if you
+can certify the below (from
+[developercertificate.org](https://developercertificate.org/)):
+
+```
+Developer Certificate of Origin
+Version 1.1
+Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
+660 York Street, Suite 102,
+San Francisco, CA 94110 USA
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+Developer's Certificate of Origin 1.1
+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
+    indicated in the file; or
+(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.
+(d) I understand and agree that this project and the contribution
+    are public and that a record of the contribution (including all
+    personal information I submit with it, including my sign-off) is
+    maintained indefinitely and may be redistributed consistent with
+    this project or the open source license(s) involved.
+```
+
+then you just add a line to every git commit message:
+
+    Signed-off-by: Joe Smith <joe@gmail.com>
+
+using your real name (sorry, no pseudonyms or anonymous contributions.)
+
+You can add the sign off when creating the git commit via `git commit -s`.
+
+## Code Reviews
+
+* The pull request title should describe what the change does and not embed issue numbers.
+The pull request should only be blank when the change is minor. Any feature should include
+a description of the change and what motivated it. If the change or design changes through
+review, please keep the title and description updated accordingly.
+* A single approval is sufficient to merge. If a reviewer asks for
+changes in a PR they should be addressed before the PR is merged,
+even if another reviewer has already approved the PR.
+* During the review, address the comments and commit the changes
+_without_ squashing the commits. This facilitates incremental reviews
+since the reviewer does not go through all the code again to find out
+what has changed since the last review. When a change goes out of sync with main,
+please rebase and force push, keeping the original commits where practical.
+* Commits are squashed prior to merging a pull request, using the title
+as commit message by default. Maintainers may request contributors to
+edit the pull request tite to ensure that it remains descriptive as a
+commit message. Alternatively, maintainers may change the commit message directly.
