 You can install Rust via [`rustup`](https://www.rustup.rs/). We currently build correctly on Rust 1.24.1, but frequently build on the nightly channel in development to enable formatting of generated bindings. The nightly channel should not be *required* however, and if it is, that's a bug.

-### Launch via xray_cli
+## Running
 
 We currently *only* support launching the application via the CLI. For this to work, you need to set the `XRAY_SRC_PATH` environment variable to the location of your repository. The CLI also currently *requires* an argument:
 
 ```sh
-XRAY_SRC_PATH=. cargo run -p xray_cli .
+XRAY_SRC_PATH=. script/xray .
 ```
+
+That assumes you built with `--release`. To run the debug version, use `xray_debug` instead:
+
+```sh
+XRAY_SRC_PATH=. script/xray_debug .
+```
+
+## Running tests and benchmarks
+
+* All tests: `script/test`
+* Rust tests: `cargo test` in the root of the repository or a Rust subfolder.
+* Front-end tests: `cd xray_electron && npm test`
+* Benchmarks: `cargo bench`
