 # Decky Frontend Library
+
+Library used to develop plugins used for use with [decky-loader](https://github.com/SteamDeckHomebrew/decky-loader).
+
+## Decky Loader Discord [![Chat](https://img.shields.io/badge/chat-on%20discord-7289da.svg)](https://discord.gg/ZU74G2NJzk)
+
+Please contact the developers here for questions and support that cannot be addressed via a Github issue.
+
+## Developers and Contributors
+
+This library is focused on usage by developers to provide custom React components based on those found in the Steam Deck's React UI.  
+This method allows developers to add UI elements and code without clobbering the existing UI of the deck in order to do so.  
+This library can also theoretically be used to extend existing UI elements of the Steam Deck UI but this has not been tested extensively.
+
+### Getting Started (Contributors)
+
+1. Clone the repository to your preferred location
+2. If you wish to add features such as new UI components, please create a feature branch to PR to the original repo.
+3. Bug/hotfixes are acceptable on the main branch,
+
+### Getting Started (Developers)
+
+If you would like a feature added to decky-frontend-lib, please request it via a Github issue.  
+
+If you want to start making a plugin with decky-frontend-lib, please direct your attention to the [decky-plugin-template](https://github.com/SteamDeckHomebrew/decky-plugin-template) repository.
+
+This library can be found on [npm](https://www.npmjs.com/package/decky-frontend-lib) and as such you can pull it without a local copy for your project as needed.
