• No Distribution of Modified Versions: You may not distribute modified versions of the software, whether in source or binary form.
• No Forking: You may not create, maintain, or distribute a forked version of the software.
• Official Distribution: Only the maintainers of the official repository are allowed to distribute the software and its modifications.
