+**Make sure your patch is as small as possible, so try to introduce as little changes as possible.** Sometimes this may require some additional thoughts about changes you make, and you may prefer a different approach to ensure a small patch difference.

 ## Helpful tips for contributions
 Because tModLoader is a big project, we want to make sure contributions don't introduce unnecessary code or code that is fundamentally flawed by design. But please don't be discouraged! If you are unsure about your contribution, still feel free to propose it and in your proposal ask us for feedback. If you do, please add "WIP:" in the title of your proposal. It is also helpful if you are specific about what you want feedback on. We will always try to provide you feedback in a passive and helpful manner.
