 MONAI Model Zoo hosts a collection of medical imaging models in the [MONAI Bundle](https://docs.monai.io/en/latest/bundle_intro.html) format.
 
 ## Model Storage
-Github limits the size of files allowed in the repository (see [About size limits on GitHub](https://docs.github.com/en/repositories/working-with-files/managing-large-files/about-large-files-on-github)). Therefore, MONAI Model Zoo suggests to use Git Large File Storage (LFS) to store large files for any single file that is larger than 25MB.
