Import MD from github or local files

Hello,

I’m looking to import a few 100 files from a github repo of mine onto my website, and was wondering if there is a tool or scrip that could automate that?

And if there isn’t if you could add such functionality?
The absolute minimum would be a function call with a security key that takes the page name and markdown content end enters/updates it in the DB. The reading of files I can do in C myself.

Cheers
David
