 # repo containing configs and scripts to set up a box
 
 ### prerequisites
-- git is installed (to clone repo below, consider adding logic to handle automatically)
+- when running on a fresh system, ensure package manager is configured
+    - i.e. source repos, mirrors, etc. are configured
+    - if on macOS, have to first install the package manager, [homebrew](https://brew.sh/)
 - zsh is installed (scripts are written for zsh)
     - ensure ZDOTDIR is set in a persistent way for system (not just setup scripts)
     - current approach: add `export ZDOTDIR="$HOME/.config/zsh"` to `/etc/zshenv`
 - export the env var `BOX_SETUP_OS` to indicate the operating system
-    - options defined in `set_env_vars` file
-- if on macOS, install [homebrew](https://brew.sh/)
+    - options defined in `set_script_env_vars` file
 - ensure sudo access is configured for the current user (2025-01-27, not needed on macos)
 
 ### script run
-- git clone this repo
+- git clone this repo (TODO: consider adding logic to handle automatically)
 - from the repo's root directory, run `./box_setup`
