There is no public upload here. Put your zip somewhere we can download it, then send us the link. If we accept it, we re-host the file ourselves so visitors get a checked download from this site.
Zip your mod so it installs cleanly. Use a clear folder layout and a short readme with install notes, credits, and any requirements. We don't accept maps or buses that require DLC or external dependencies, everything must be bundled in one simple zip.
Upload the zip to a host we can reach, such as Google Drive, Dropbox, Mega, or similar. This link is for us to fetch the file - not the final public download on OmsiWorld.

We download your file, check it by hand, and scan it before anything goes live. That way we control what people get from this site and reduce the risk of bad or unsafe packages.
If it fits the archive, we re-host it on our side and list it here. We may tidy packaging, ask for a clearer link, or decline if it does not fit. We read messages, but cannot promise a personal reply to every submission.
