Possible to use a .txt file in your repo as a wiki page?

Hey all. We’ve been using gitlab’s wiki as our software wiki at our small company since we started.

I just started using the KaTeX markdown today to write a page on an algorithm we’re using and I thought it would be neat if I could edit that long heavy page in my desktop IDE (on some .txt or .tex file for example).

Is it possible for a wiki page on gitlab to just reference a file in our repo? That way I can edit it in my IDE (more preferable for me) and commit it, and then the wiki page would automagically update with that commit.
