 ## Running Benchmarks
 
 Benchmarks for the parser itself are done using `cargo bench`, while any external parser is benchmarked using [hyperfine].\
-To run specific benchmarks, execute `/.run` in the directory of the respective parser.
-It sets up dependencies and runs `sudo` so it is only recommended to be used in an isolated environment and is only tested using the devcontainer, other platforms might require additional dependencies to be installed.
+To run a specific benchmark execute `just bench-$PARSER-NAME` or `just benchmark-comparison` to run all benchmarks. This will setup required dependencies and run `sudo` so it is only recommended to be used in an isolated environment and is only tested using the devcontainer, other platforms might require additional dependencies to be installed. A working installation of `just` and `cargo` is assumed.
