i was trying to explain how you know what directory to add to your PATH when using a new installer (npm, cargo, homebrew, bundler, go, etc) and it was way more difficult to explain than I thought. it feels like
- ideally you remember from last time
- or the tool prints out directions the first time you use it (but never again)
- or you look in the docs which is NOT as easy as it seems (I tried to find it and it was hard!)
- or you go to stack overflow which will probably get you there
