+# Contributing guidelines
+
+Thank you (again) for your interest in the project!
+
+## Talk to us before commiting to a change
+
+We recommend you come and talk to us in the channel and/or open an issue
+before you start working on a feature, to **see if it aligns with our goals**.
+
+We'll do our best to review and discuss changes with you but we're also humans
+with other activities, please be patient with us too.
+
+## General guidelines
+
+The library is still **in development**, and while this is the case we adopt a
+**fail-fast** strategy, which is also a reason for the choice of the language.
+
+The earlier we catch bugs and fix them, the less chances they have to confuse
+users of our library, or make end-users give up on software developed using
+this library. This also helps improving other software in the ecosystem.
+
+## Keep commits short and meaningful
+
+To help with reviews, to facilitate reverts, reading and grepping through
+commit history, bisects: it is important for us that changes come in small and
+meaningful commits.
+
+That is, **don't bundle all the things in a single commit**, if a change can
+be added via different commits standalone and still make sense, then it's
+probably a good candidate for splitting.
+
+## Meta
+
+Do not forget to **update changelogs** and other crate metadata where necessary.
+
+Signing commits (`git commit -S`) and adding DCO bits (`git commit -s`) are
+welcome but not mandatory.
+
+## Ensure CI passes
+
+Code changes should **include documentation**. They should also **include
+tests** where appropriate, and pass the existing test suite.
+
+CI should pass to submit your changes. This is done by ensuring `cargo
+fmt` and `cargo test` pass (in the workspace). Please run `cargo fmt` as part
+of each of your commits.
+
+More thorough tests can be done locally with `act` or `forgejo-runner
+exec`, which is also what is run in the CI. We require docker to be setup for
+this to work.
