+Thanks for contributing a merge request! Please name and fully describe your MR as you would for a commit message.
+If the MR fixes an issue, please include "Fixes #issue" in the commit message and the MR description.
+
+In addition, we recommend that first-time contributors read our [contribution guidelines](https://eigen.tuxfamily.org/index.php?title=Contributing_to_Eigen) and [git page](https://eigen.tuxfamily.org/index.php?title=Git), which will help you submit a more standardized MR.
+
+Before submitting the MR, you also need to complete the following checks:
+- Make one PR per feature/bugfix (don't mix multiple changes into one PR). Avoid committing unrelated changes.
+- Rebase before committing
+- For code changes, run the test suite (at least the tests that are likely affected by the change).
+  See our [test guidelines](https://eigen.tuxfamily.org/index.php?title=Tests).
+- If possible, add a test (both for bug-fixes as well as new features)
+- Make sure new features are documented
+
+Note that we are a team of volunteers; we appreciate your patience during the review process.
