 Before you proceed, please read the following:
 
+* One request or bug report per issue, please. No bundling.
 * If you are reporting a bug, please attach the latest application log file together with description of steps that lead to the issue. They can be found in the user directory under `.diylc/logs` directory. On Windows 7 and later, it's located in `c:/Users/<your username>/.diylc/logs`. On Linux and MacOS, it's typically in `/Users/<your username>/.diylc/logs`.
 * If you are having issues starting the application under MacOS, make sure that 3rd party apps are allowed on your Mac. This document covers how to do it - https://support.apple.com/en-us/HT202491.
 * Try to look for similar unresolved issues that are already reported to avoid duplicates.
