+## Contribution rules
+
+While we want DbToolsBundle to be a community project, **we do not accept any kind of contribution**.
+
+We ask our contributors to follow these simple rules:
+
+### Basic courtesy
+
+Each issue and PR must be introduced with a clear description that expose the problem it solves or the feature
+it implements.
+
+_Each wild PR that does not comply with this rule won't be read_
+
+### PR without associated issue
+
+Note that we accept PR which are not relative to an existing issue (as long as it complies with the previous rule).
+
+But we encourage you not do it. Proposing a PR without discussing the problem/the feature with maintainers can
+lead to useless work.
+
+### Split your contributions
+
+It is much easier for mainteners to review small PRs that solve one and only one issue.
+
+- Do not correct multiple issues in the same ticket (unless discussed and approved in advance)
+- Do not make changes that are too invasive or too large (unless discussed and approved in advance)
+
+### Mind the documentation
+
+We care a lot about documentation and changelog.
+
+We consider that a feature which is not documented does not exist. So if you add a new
+feature, document it in the correct section of our documentation.
+
+Whether you are fixing a bug or developing a new feature : mention it in the `CHANGELOG.md` file.
+
+This file already contains a lot of content, you should quickly understand the expected syntax.
+
+### Ask for help
+
+If you encounter problem while contributing, we encourage you to ask us for help.
+
+Don't hesitate to push draft PRs and to ping mainteners!
+
+### Ok for AI, but in good intelligence
+
+While we are no big fan of AI, we accept our contributor to use it.
+
+**But**
+
+Your use of AI should not cost to us. AI is just a tool to produce code, it is your responsability to ensure that
+the produced code complies with all the previous rules.
+
+This being said:
+
+- We won't accept completely vide-coded PRs
+- A PR that does not appear to have been properly reviewed by its own author after using AI will be closed
