 # Feishin
 
+> **⚠️ Fork Notice**: This is a fork of the original [Feishin](https://github.com/jeffvli/feishin) project. I created this fork primarily to add folder view functionality that the original repo wasn't able to accommodate, along with some other features I found useful. While I'll try to keep this fork in sync with the original repo, that's not the primary focus. Feishin was pretty much perfect for me - I just missed the folder view feature. That said, I'll fix any obvious bugs I encounter, but for full support and the most up-to-date version, please stay with the original repository.
+>
+> **Note**: I primarily use Linux desktop, so only Linux issues can be addressed if needed.

 ### Desktop (recommended)
 
-Download the [latest desktop client](https://github.com/jeffvli/feishin/releases). The desktop client is the recommended way to use Feishin. It supports both the MPV and web player backends, as well as includes built-in fetching for lyrics.

 We provide a small install script to download the latest `.AppImage`, make it executable, and also download the icons required by Desktop Environments. Finally, it generates a `.desktop` file to add Feishin to your Application Launcher.
 
 Simply run the installer like this:

 ```sh
 dir=/your/application/directory
 curl 'https://raw.githubusercontent.com/jeffvli/feishin/refs/heads/development/install-feishin-appimage' | sh -s -- "$dir"

 The script also has an option to add launch arguments to run Feishin in native Wayland mode. Note that this is experimental in Electron and therefore not officially supported. If you want to use it, run this instead:

 ```sh
 dir=/your/application/directory
 curl 'https://raw.githubusercontent.com/jeffvli/feishin/refs/heads/development/install-feishin-appimage' | sh -s -- "$dir" wayland-native
