-* **Describe the exact steps which reproduce the problem** in as many details as possible. For example, start by explaining how you started Marlin, e.g. which command exactly you used in the terminal, or how you started Marlin otherwise. When listing steps, **don't just say what you did, but explain how you did it**. For example, if you moved the cursor to the end of a line, explain if you used the mouse, or a keyboard shortcut or an Marlin command, and if so which one?
-* **Provide specific examples to demonstrate the steps**. Include links to files or GitHub projects, or copy/pasteable snippets, which you use in those examples. If you're providing snippets or log output in the issue, use [Markdown code blocks](https://help.github.com/articles/markdown-basics/#multiple-lines).
-* **Describe the behavior you observed after following the steps** and point out what exactly is the problem with that behavior.
-* **Explain which behavior you expected to see instead and why.**
-* **Include detailed log output** especially for probing and leveling. See below for usage of `DEBUG_LEVELING_FEATURE`.
-* **Include screenshots, links to videos, etc.** which clearly demonstrate the problem.
