FIX: Parsing .md docs file compiles

[JackDra]

Summary

For some reason, I was getting a formatting error when building and previewing the docs.
Looked into the parsing, and got it working by replacing the regex with just a line split.
I was working on windows, so maybe its a file read utf-8 issue...?
