 Yet another Nostr desktop client
 
+## Features
+
+- **Relay-Based Browsing:** Explore content directly through relays without following specific users. Discover diverse topics across different relays
+- **Relay-Friendly Design:** Minimized and simplified requests ensure efficient communication with relays
+- **Relay Groups:** Organize similar relays into custom groups for seamless switching between different content streams
+- **Clean Interface:** Enjoy a minimalist design and intuitive interactions
+
+## Download
+
+You can download the latest version from the [release page](https://github.com/CodyTseng/jumble/releases). If you want to use Apple Silicon version, you need to build it from the source code.
+
+Because the app is not signed, you may need to allow it to run in the system settings.
+
 ## Build from source
 
 You can also build the app from the source code.
