Please could I get some feedback for this PR?

Sorry for the delay! The new section does a good job at explaining why/when conflicts occur. However, it does not document the best practices mentioned in the issue description. For example, using a custom annotation and/or a custom parameter type. Could you please add that?

Thanks for the feedback! I've added examples of using a custom type and a custom annotation.

Thanks, I think it's very thorough now! I polished it a bit but it was already in great shape. 👍
