+# How to contribute
+
+As for all great Open Source projects, contributions in form of bug reports and code are welcome and important to keep the project alive.
+
+In general, this project follows the [GitHub Flow](https://guides.github.com/introduction/flow/).
+Fork the project, commit your changes to your branch, open a pull request and it will probably be merged.
+However, to ensure maintainability and quality of the code, there are some guidelines you might be more or less familiar with.
+For that purpose, this document describes the important points.
+
+## Opening an Issue
+
+If you experience any issues with the library or the code, don't hesitate to file an issue.
+
+### Bug Reports
+
+Think you found a bug?
+Please clearly state what happens and describe your environment to help tracking down the issue.
+
+* Which version of the connector are you running?
+* Which version of Java (architecture and OS if relevant)?
+* Which version of Vault?
+
+### Feature Requests
+
+Missing a feature or like to have certain functionality enhanced?
+No problem, please open an issue and describe what and why you think this change is required.
+
+## Pull Requests
+
+If you want to contribute your code to solve an issue or implement a desired feature yourself, you might open a pull request.
+If the changes introduce new functionality or affect major parts of existing code, please consider opening an issue for discussion first.
+
+Extending or adapting JUnit test cases would be nice (no hard criterion though).
+
+The `main` branch also be target for most pull requests.
+However, if it features new functionality you might want to target the `develop` branch instead (see next section for details on branches).
+
+### Branches
+
+The `main` branch represents the current, more or less stable state of development.
+Please ensure your initial code is up to date with it at the time you start development.
+
+In addition, this project features a `develop` branch, which holds bleeding edge developments, not necessarily considered stable or even compatible.
+Do not expect this code to run smoothly, but you might have a look into the history to see if some work on an issue has already been started there.
+
+For fixes and features, there might be additional branches, likely prefixed by `fix/` or `feature/` followed by an issue number (if applicable) and/or a title.
+Feel free to adapt this naming scheme to your forks.
+
+### Merge Requirements
+
+To be merged into the main branch, your code has to pass the automated continuous integration tests, to ensure compatibility.
+In addition, your code has to be approved by a project member.
+
+#### What if my code fails the tests?
+
+Don't worry, you can submit your PR anyway.
+The reviewing process might help you to solve remaining issues.
+
+### Commit messages
+
+Please use speaking titles and messages for your commits, to ensure a transparent history.
+If your patch fixes an issue, reference the ID in the first line.
+If you feel like you have to _briefly_ explain your changes, do it (for long explanations and discussion, consider opening an issue or describe in the PR).
+
+**Example commit:**
+```text
+Fix nasty bug from #1337
+
+This example commit fixes the issue that some people write non-speaking commit messages like 'done magic'.
+A short description is helpful sometimes.
+```
+
+You might sign your work, although that's no must.
+
+### When will it be merged?
+
+Short answer: When it makes sense.
+
+Bugfixes should be merged in time - assuming they pass the above criteria.
+New features might be assigned to a certain milestone and as a result of this be scheduled according to the planned release cycle.
+
+## Compatibility
+
+To ensure usability for a wide range of users, please take note on the software requirements stated in the `README`.
+This includes especially Java versions and a minimum version of _Vault_.
+
+If you are unsure if your code matches these versions, the test will probably tell you.
+
+In case you think, your change is more important than maintaining backwards compatibility, please start a discussion to see,
+if we might increase the minimum version or find a workaround for legacy systems.
+
+## Build Environment
+
+All you need to start off - besides your favorite IDE and a JDK of course - is [Maven](https://maven.apache.org/).
+
+## Unit Tests
+
+The code is tested by JUnit tests.
+For standalone testing against mocked APIs the _Maven_ profile `offline-test` should be used.
+Otherwise, there is a test suite that requires an actual _Vault_ binary in the executable path to start a real server instance. 
+
+## Continuous Integration
+
+Automated tests are run using [GitHub Actions](https://github.com/features/actions) for every commit including pull requests.
+Tests usually run against the minimal supported version, all supported LTS versions and the latest version of Java.
+
+There is an automated code quality analysis pushing results to [SonarCloud](https://sonarcloud.io/dashboard?id=de.stklcode.jvault%3Ajvault-connector).
+
+## Still Open Questions?
+
+If anything is still left unanswered and you're unsure if you got it right, don't hesitate to contact a team member.
+In any case you might submit your request/issue anyway, we won't refuse good code only for formal reasons.
