+# Pac
+
+Pac is a simple pacman wrapper that provides intuitive syntax similar to
+`dnf`, `apt`, `zypper`, etc.
+
+With `pac` you don't need to memorize the non-intuitive options like
+`-Rs`, `-Ss`, `-Si`; you can just type `remove`, `search`, `info`,
+respectively.
+
+> **Note**: Pac itself is not an AUR helper, though it can wrap an AUR helper
+> that supports pacman's options. See [Configuration](#configuration).
+
+## Installation
+
+To install from source, run `makepkg -si`.
+
+## Usage
+
+- To upgrade installed packages, run `pac`.
+- To install package `foo`, run `pac install foo` or `pac in foo`.
+- To remove package `foo`, run `pac remove foo` or `pac rm foo`.
+- To show information about package `foo` (whichever installed or not, or a
+  package group or not), run `pac info foo` or `pac if foo`.
+- To mark package `foo` as dependencies, run `pac mark --asdeps foo` or
+  `pac mark -d foo`.
+- To remove dependencies that are no longer required by any installed package,
+  run `pac autoremove`.
+- To list explicitly installed foreign packages (e.g. AUR packages), run
+  `pac list --explicit --foreign` or `pac ls -e -f`.
+
+Run `pac --help` for more information.
+
+## Configuration
+
+By default, `pac` wraps `pacman`. To wrap another pacman-compatible program,
+set the environment variable `PAC_PACMAN`.
+
+For example, to wrap `paru` instead of `pacman`, add
+
+```sh
+export PAC_PACMAN='paru'
+```
+
+to your `~/.bash_profile` (or `$ZDOTDIR/.zshenv` for Zsh) and reload your shell.
+
+## TODO
+
+- Support Tab completion for bash and zsh.
