 # Servo WebView for Qt using CXX-Qt
 
-TODO
+KDAB has built a demo of using [CXX-Qt](https://github.com/KDAB/cxx-qt/) to expose a [Servo](https://servo.org/) in Rust as a component to Qt.
 
-# Setup
+## Setup
 
-We need the nightly compiler for now.
+* Ensure that you have Qt installed and `qmake` in your `PATH`.
+* Ensure that you have the dependencies of `./mach boostrap` from the [https://github.com/servo/servo/](https://github.com/servo/servo/) repository.
+* Alternatively use the `shell.nix`
+* Install the nightly compiler from February
 
 ```console
-rustup install nightly-2024-02-01
-rustup default nightly-2024-02-01
+$ rustup install nightly-2024-02-01
+$ rustup default nightly-2024-02-01
 ```
 
-# Notes
+* Then run in release mode
 
-## cargo.lock
+```console
+$ cargo run --release
+```
 
-We need to copy the cargo.lock from the servo repository to ensure we have the correct patched versions of crates.
