 ## Configuring Emacs {#sec-emacs-config}
 
-The Emacs package comes with some extra helpers to make it easier to configure. `emacsWithPackages` allows you to manage packages from ELPA. This means that you will not have to install that packages from within Emacs. For instance, if you wanted to use `company` `counsel`, `flycheck`, `ivy`, `magit`, `projectile`, and `use-package` you could use this as a `~/.config/nixpkgs/config.nix` override:

 This provides a fairly full Emacs start file. It will load in addition to the user's presonal config. You can always disable it by passing `-q` to the Emacs command.
 
-Sometimes `emacsWithPackages` is not enough, as this package set has some priorities imposed on packages (with the lowest priority assigned to Melpa Unstable, and the highest for packages manually defined in `pkgs/top-level/emacs-packages.nix`). But you can't control this priorities when some package is installed as a dependency. You can override it on per-package-basis, providing all the required dependencies manually - but it's tedious and there is always a possibility that an unwanted dependency will sneak in through some other package. To completely override such a package you can use `overrideScope'`.
