I need to add a gif to a readme file in my repository, but the size of the gif extends 25mb that is the maximal possible filesize for a file a repository. So I cannot store the gif in the repository. Where can I store the gif for the markdown file? Or is it impossible to add a large gif to the readme file?
You can store/host it remotely and reference it from the readme file using <img src="..."> or md syntax.
