My process has been:
Install Atom, TeX Live and MikTex (was gonna check out which I liked better). Install the latex (0.43.0) package and some accompanying packages to compliment it. Tried compiling my first document and failed. Installed Perl, installed latexmk via TeX Live. It didn’t work, but when I tried compiling I got a popup (from MiKTeX?) asking how I’d like to install packages (internet, folder …), from where, etc. Clicked OK with whatever the default option was and I think latexmk was installed. Tried compiling again and it worked.
I’d like to use Atom for academic writing so I installed textgreek, but I have no idea how to get it to work with Atom. It’s installed in MiKTeX … but now what? How do I get it to show up in Atom?
