 If you would like to reach out to a mentor privately rather than making a public forum post, and the forums are not allowing you to send private messages yet, please reach out to Konrad Malawski at `ktoso AT apple.com` directly via email with the `[gsoc2025]` tag in the email subject and describe the project you would like to work on. We will route you to the appropriate mentor. In general, public communications on the forums are preferred though, as this is closer to the normal open-source way of getting things done in the Swift project.
 
+We discourage the use of AI and/or LLM technologies in proposal authoring, communication and contributions. Summer of Code is a program aiming at forming human connections and help contributors to understand and join the Open Source community. We strongly value genuine discussion and would prefer proposals are written in your own voice, and understanding of the subject area.

 ## Writing a proposal
 
 Getting familiar with the codebase you are interested in working on during GSoC helps to write a good proposal because it helps you get a better understanding of how everything works and how you might best approach the project you are interested in. How you want to do that is really up to you and your style of learning. You could just clone the repository, read through the source code and follow the execution path of a test case by setting a breakpoint and stepping through the different instructions, read the available documentation or try to fix a simple bug in the codebase. The latter is how many open-source contributors got started, but it’s really up to you. If you do want to go and fix a simple bug, our repositories contain a label “good first issue” that marks issues that should be easy to fix and doable by newcomers to the project.
 
 When it comes to writing the proposal, the [Google Summer of Code Guide](https://google.github.io/gsocguides/student/writing-a-proposal) contains general, good advice.
 
+The best proposals include a detailed timeline, specific milestones and goals as well as an outline the technical challenges you foresee. It is best if you engage with your potential project mentor on the forums before contributor, and have them clarify the goals and steps that they think are necessary for the project to be successful. Your proposal should have a clear goal, which can be successfully achieved as part of the weeks you'll be working it. Provide details about your approach, significant milestones you wish to achieve, and clarify with your potential mentor if they agree those seem reasonable. The time before proposal submissions is there for you to reach out and polish your proposal, so make sure you use it well! Good luck!
