+# Syncthing Deck Setup
+
+This script will download a Syncthing build and install it in the user's home
+directory. This allows a user to run Syncthing using a SystemD user service, and
+keep all necessary files within their home directory. In scenarios where the
+traditional directory for installed packages may be overwritten (ie., the Steam
+Deck's filesystem), this allows Syncthing to persist through updates, and still
+run automatically in the background when the Deck is started. There is no GUI
+provided for Syncthing when installed this way. Instead, use the web-UI
+available at `localhost:8384`.
+
+## Requirements
+
+- `bash`
+- `curl`
+- `tar`
+
+## Usage
+
+Run the script. Optionally include a version, a platform, and an architecture.
+Acceptable values can be found on the [Syncthing
+Releases](https://github.com/syncthing/syncthing/releases) page.
+
+```
+Usage: syncthing-deck-setup [<options>]
+
+    -V, --version   Specify a Syncthing Version. Default is latest.
+   -P, --platform   Specify an OS/Platform. Default is linux.
+       -A, --arch   Specify an architecture. Default is amd64.
+  -U, --uninstall   Remove files setup with this script.
+               -v   Show version
+               -h   Show this usage
+```
