# package.el-based emacs packages

## FOR USERS
#
# Recommended: simply use `emacsWithPackages` with the packages you want.
#
# Alternative: use `emacs`, install everything to a system or user profile
# and then add this at the start your `early-init.el`:
/*
  ;; optional. use this if you install emacs packages to the system profile
  (add-to-list 'package-directory-list "/run/current-system/sw/share/emacs/site-lisp/elpa")

  ;; optional. use this if you install emacs packages to user profiles (with nix-env)
  (add-to-list 'package-directory-list "~/.nix-profile/share/emacs/site-lisp/elpa")
