+You can use the `./x perf <command> [options]` command to use this integration.
 
 You can use normal bootstrap flags for this command, such as `--stage 1` or `--stage 2`, for example to modify the stage of the created sysroot. It might also be useful to configure `config.toml` to better support profiling, e.g. set `rust.debuginfo-level = 1` to add source line information to the built compiler.
