I use MiKTeX and TeXstudio, and I'm trying to install REVTeX. As I'm not tech savvy, I'm having difficulties, and whenever I have searched online for help, all the answers are written presupposing some knowledge. The "README" instructions also presupposed knowledge. I have tried reading documentation to figure out how to do this and learn background knowledge, yet I'm still stuck.
So far, I downloaded and unzipped the file from APS and was left with "revtex-tds". From what I could figure out, I made a folder titled "latex" in a folder titled "tex" in a folder titled "packages" in my c-drive and put "revtex-tds" into the "latex" folder. I went into MiKTeX console into "Directories" in "Settings", and added a path to the "packages" folder. I clicked "Refresh filename database" under "Tasks". Nothing happened, and when I wrote "\documentclass{revtex4-2}", it said "class: revtex4-2 (not found)".
Let me know if I've done something wrong and what I need to be doing - please & thank you!
