 # xdg-sanity
 
-This script is built to replace your default web browser in your desktop/XDG
-settings. It intercepts http/s URIs sent to the default browser by XDG settings
-and sends it to the appropriate application. For example, it will send
-image/jpeg MIME type files to your image viewer.
+The `xdg-sanity` script is built to replace your default web browser in your
+desktop/XDG settings. It intercepts http/s URIs sent to the default browser by
+`xdg-open` and sends it to the appropriate application. For example, it will
+send `image/jpeg` MIME type files to your image viewer.
 
-Add your default web browser to `/etc/xdg-sanity.conf` so the script can forward
-links to it.
+## Installation
+
+### Arch
+
+I maintain a package [on the
+AUR](https://aur.archlinux.org/packages/xdg-sanity).
+
+### From Source
+
+First, make sure you have `curl(1)` and `handlr(1)` installed. Then, clone this
+repository and move the `xdg-sanity/` folder into `/etc` and `xdg-sanity.sh` to
+`xdg-sanity` wherever your operating system stores locally-installed binaries.
+This is usually `/usr/local/bin`. Make sure the installation location is in your
+`$PATH`.
+
+Create a `xdg-sanity.desktop` file either manually or with `gendesk(1)`,
+placing it, also, where your OS stores locally-installed `.desktop` files,
+usually `/usr/local/applications`. Set your default web browser to that
+`.desktop` file.
+
+Add your default web browser to `/etc/xdg-sanity/xdg-sanity.conf` so the
+script can forward links to it.
+
+### Usage
+
+Open links from applications outside your web browser as normal. Alternatively,
+you can call `xdg-sanity` directly with the only argument accepted being a URI.
