 # Ladybird
 
-Ladybird is a web browser built on the [LibWeb](https://github.com/SerenityOS/serenity/tree/master/Userland/Libraries/LibWeb) and [LibJS](https://github.com/SerenityOS/serenity/tree/master/Userland/Libraries/LibJS) engines from [SerenityOS](https://github.com/SerenityOS/serenity) with a cross-platform GUI in Qt.
+Ladybird is a web browser built on the [LibWeb](https://github.com/SerenityOS/serenity/tree/master/Userland/Libraries/LibWeb) and [LibJS](https://github.com/SerenityOS/serenity/tree/master/Userland/Libraries/LibJS) engines from [SerenityOS](https://github.com/SerenityOS/serenity).
+The Browser UI has a cross-platform GUI in Qt6 and a macOS-specific GUI in AppKit.
 
-For more information about Ladybird, see [this blog post](https://awesomekling.github.io/Ladybird-a-new-cross-platform-browser-project/).
+Ladybird aims to be a standards-compliant, independent web browser with no third-party dependencies.
+Currently, the only dependencies are UI frameworks like Qt6 and AppKit, and low-level platform-specific
+libraries like PulseAudio, CoreAudio and OpenGL.
 
-See [build instructions](../Documentation/BuildInstructionsLadybird.md).
+> [!IMPORTANT]
+> Ladybird is in a pre-alpha state, and only suitable for use by developers
+
+## Features
+
+The Ladybird browser application uses a multiprocess architecture with a main UI process, several WebContent renderer processes,
+an ImageDecoder process, a RequestServer process, and a SQLServer process for holding cookies.
+
+Image decoding and network connections are done out of process to be more robust against malicious content.
+Each tab has its own renderer process, which is sandboxed from the rest of the system.
+
+All the core library support components are developed in the serenity monorepo:
+
+- LibWeb: Web Rendering Engine 
+- LibJS: JavaScript Engine
+- LibWasm: WebAssembly implementation
+- LibCrypto/LibTLS: Cryptography primitives and Transport Layer Security (rather than OpenSSL)
+- LibHTTP: HTTP/1.1 client
+- LibGfx: 2D Graphics Library, Image Decoding and Rendering (rather than skia)
+- LibArchive: Archive file format support (rather than libarchive, zlib)
+- LibUnicode, LibLocale: Unicode and Locale support (rather than libicu)
+- LibAudio, LibVideo: Audio and Video playback (rather than libav, ffmpeg)
+- LibCore: Event Loop, OS Abstraction layer
+- LibIPC: Inter-Process Communication
+- ... and more!
