+# Goodreads Libby Userscript
+
+Userscript that will search for the book you are looking at on Goodreads across all your libby libraries.
+
+## Installation
+
+1. Make sure you have a browser extension that can run userscripts:
+
+    * [Tampermonkey](https://www.tampermonkey.net/)
+    * [Violentmonkey](https://violentmonkey.github.io/get-it/)
+    * [Greasemonkey](https://addons.mozilla.org/firefox/addon/greasemonkey/)
+
+2. Install:
+
+    * Install the script directly from GitHub through this link: [Install](https://github.com/Dylancyclone/goodreads-libby-userscript/raw/main/goodreads-libby.user.js).
+    * Install the script from [GreasyFork](https://greasyfork.org/en/scripts/440958-goodreads-libby-results) (GF)
+<!-- * Or, install the scripts from [OpenUserJS](https://openuserjs.org/users/Dylancyclone/scripts) (OU). -->
+
+## Usage
+
+Go to the libby web app's main menu (https://libbyapp.com/interview/menu) and click the "Save Libraries" button.
+
+![The Save Libraries button](./libby.png)
+
+Then, search for a book on Goodreads. When you've found a book, the userscript will search across all your libby libraries and show the results on the left side of the screen.
+
+![The search results on Goodreads](./goodreads.png)
+
+You can then click the number of results to be taken to the search page for that library.
+
+## Updating
+
+Userscripts are set up to automatically update. You can check for updates from within the Greasemonkey or Tampermonkey menu, or click on the install link again to get the update.
+
+## Issues
+
+Please report any issues within this repository's [issue section](https://github.com/Dylancyclone/goodreads-libby-userscript/issues). I'm not a very active userscript developer, so Greasyfork messages are a little more difficult to work with. Thanks!
