-# Contributing to MySqlConnector
-
-Firstly, thank you for wanting to contribute to the project!
-
-### General Guidelines
-
-If there's not already an issue describing the problem you want to fix, please create one. Otherwise,
-add a comment to the existing issue, indicating that you want to work on it.
-
-Please read [how to run the tests](../tests/README.md) and run them locally before opening your pull request.
-All pull requests will be tested automatically; PRs with failing tests will not be accepted.
-
-All PRs that add new functionality must also include tests that verify the new functionality. This is important
-to ensure that compatibility with `MySql.Data` is maintained.
-
-This project uses the [Developer Certificate of Origin](https://developercertificate.org/). In short, you
-must add a `Signed-off-by: Your Name <email@example.com>` line to the bottom of your commit
-message to indicate that you accept the DCO and have the right to submit your contributions. You
-can use `git commit -s` to automatically add this line to your commit message. [Learn more](https://probot.github.io/apps/dco/)
-
-### Code Guidelines
-
-Please install an [Editorconfig plugin](http://editorconfig.org/#download) in your favourite editor so that your
-source code follows the repo style.
-
-Commit messages should generally follow [these guidelines](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html).
-
-Each commit should contain one logical change. If some refactoring is necessary before your
-patch can be written, commit that as a separate change first. This allows the independent parts
-of the PR to be reviewed separately. This [post on commit messages](http://who-t.blogspot.com/2009/12/on-commit-messages.html)
-has helpful recommendations.
