### Tips for increasing the likelihood of a response
* Use the `preformatted text` formatting option in the editor for all log entries and configuration output.
* If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
* Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
