+[brickworks/mfc-apps](https://github.com/Brickworks/mfc-apps), built on Rust.
 
 ## Installation
+
 ```sh
 cargo install --git https://github.com/Brickworks/yahs.git --features gui
 yahs --help
 ```
-
-## Usage (CLI)
-Set the simulation configuration in `config/default.toml`
-
-Then use the `start` command to start a flight simulation. Use the `RUST_LOG`
-environment variable to specify the log level to report.
-
-```sh
-yahs start
-```
-
-## Usage (GUI)
-
-```sh
-yahs gui
-```
