 # Apps
+
+Library and CLI tool for querying and launching
+applications that have a corresponding `.desktop` file.
+
+## Installation
+
+1. install dependencies
+
+:::code-group
+
+```sh [<i class="devicon-archlinux-plain"></i> Arch]
+sudo pacman -Syu meson vala json-glib gobject-introspection
+```
+
+```sh [<i class="devicon-fedora-plain"></i> Fedora]
+sudo dnf install meson gcc valac json-glib-devel gobject-introspection-devel
+```
+
+```sh [<i class="devicon-ubuntu-plain"></i> Ubuntu]
+sudo apt install meson valac libjson-glib-dev gobject-introspection
+```
+
+:::
+
+2. clone repo
+
+```sh
+git clone https://github.com/aylur/astal.git
+cd astal/lib/apps
+```
+
+3. clone repo
+
+```sh
+meson setup build
+meson install -C build
+```
+
+:::tip
+Most distros recommend manual installs in `/usr/local`,
+which is what `meson` defaults to. If you want to install to `/usr`
+instead which most package managers do, set the `prefix` option:
+
+```sh
+meson setup --prefix /usr build
+meson install -C build
+```
+
+:::
+
+## Usage
+
+You can browse the [Apps reference](https://aylur.github.io/libastal/apps).
+
+### CLI
+
+```sh
+astal-apps --help
+```
+
+### Library
+
+:::code-group
+
+```js [<i class="devicon-javascript-plain"></i> JavaScript]
+import Apps from "gi://AstalApps"
+
+const apps = new Apps.Apps({
+    includeEntry: true,
+    includeExecutable: true,

+:::info
+The fuzzy query uses [Levenshtein distance](https://en.wikipedia.org/wiki/Levenshtein_distance). I am not a mathematician, but if you know how to reimplement
+the logic of [fzf](https://github.com/junegunn/fzf) to make it better feel free to open PRs.
