That URL should be converted into markdown document with code blocks by default, if for some reason the whole document is more than 1500 lines we should split code blocks/sections of the document into separate markdown documents or code files.

So if it stays as the single file - we do just convert this url by default to markdown document, if not we pack all related files to zip archive where we have index.md and all other related files.
