Downloading mods for a game you legitimately own (any platform) is legal in most jurisdictions. Mod creators generally want their work used by as many players as possible. However, downloading full game conversions or assets from the Workshop via third-party downloaders deprives creators of Workshop statistics and endorsements. If you love a mod and can afford it, consider buying the game on Steam to subscribe and leave a positive rating for the creator. If not, a direct thank-you on Discord goes a long way.
Steam usually hides mods in a specific folder. On a non-Steam install, the path is slightly different but logical.
Navigate to:

The golden rules to remember:
While Steam Workshop offers convenience, the manual method gives you true ownership of your modded experience.

Happy dodging, and may your RNG never give you Brother Bobby.
