+# Utility
+
+Defines general aliases and functions.
+
+This module must be loaded _before_ the [_`completion`_][1] module so that the
+provided completion definitions are loaded automatically by _`completion`_
+module.
+
+**Note:** Some of the utilities configured in this module might be provided via
+GNU utilities with incompatible arguments on non-GNU systems. In such cases,
+using [_`gnu-utility`_][2] module is recommended and it must be loaded
+_before_ this module.
+
+To elaborate, the relative order of loading the modules would be
+_`gnu-utility`_, _`utility`_ and _`completion`_.
+
+## Settings
+
+### Highlighting
+
+If you have enabled color globally in _`${ZDOTDIR:-$HOME}/.zpreztorc`_, you may
+disable it selectively for certain commands.
+
+To disable `ls` color, add the following to _`${ZDOTDIR:-$HOME}/.zpreztorc`_.
+When coloring is disabled, type indicators (`\*`, `/`, `=>`, `@`, `=`, `|`, `%`)
+will be appended to entries.
+
+```sh
+zstyle ':prezto:module:utility:ls' color 'no'
+```
+
+To disable GNU coreutils `ls` to list directories grouped first, add the
+following line to _`${ZDOTDIR:-$HOME}/.zpreztorc`_:
+
+```sh
+zstyle ':prezto:module:utility:ls' dirs-first 'no'
+```
+
+To disable `grep` highlighting, add the following line to
+_`${ZDOTDIR:-$HOME}/.zpreztorc`_:
+
+```sh
+zstyle ':prezto:module:utility:grep' color 'no'
+```
+
+To disable `diff` highlighting, add the following line to
+_`${ZDOTDIR:-$HOME}/.zpreztorc`_:
+
+```sh
+zstyle ':prezto:module:utility:diff' color 'no'
+```
+
+To disable `wdiff` highlighting, add the following line to
+_`${ZDOTDIR:-$HOME}/.zpreztorc`_:
+
+```sh
+zstyle ':prezto:module:utility:wdiff' color 'no'
+```
+
+To disable `make` highlighting, add the following line to
+_`${ZDOTDIR:-$HOME}/.zpreztorc`_:
+
+```sh
+zstyle ':prezto:module:utility:make' color 'no'
+```
+
+### Download Helper
+
+To configure the download helper to be used with alias `get`, add the following
+to _`${ZDOTDIR:-$HOME}/.zpreztorc`_, and replace `'<helper>'` with `'curl'`,
+`'wget'` or `'aria2c'`.
+
+```sh
+zstyle -s ':prezto:module:utility:download' helper '<helper>'
+```

+- `lr` lists human readable sizes, recursively.
+- `la` lists human readable sizes, hidden files.
+- `lm` lists human readable sizes, hidden files through pager.

+If this is not desired, it can be disabled by adding the following line to
+_`${ZDOTDIR:-$HOME}/.zpreztorc`_:
+
+```sh
+zstyle ':prezto:module:utility' safe-ops 'no'.
+```
+
+In addition, the following aliases have been added:
+
+- `cpi` copies files and directories interactively.
+- `lni` links files and directories interactively.
+- `mvi` moves files and directories interactively.
