 Use **rebase** to keep your branch up to date.
 
+Despite this, commits from your branch can be **squashed** and merged into the main branch by **rebasing** if the changes do not require logical separation. Otherwise, it is entirely your responsibility to format the commits in your PR branch.

+## Licensing

+; Copyright (C) 2011-2025 KolibriOS team

+
+A brief description is only required for the main source file. The files included in it may not have a description.
+
+Be careful when setting copyright and date interval. Review the file's history to verify its origin.
