+A simple version of this benchmark can be run using the following commands:
 
 .. code-block::
 
    $ pip install -U benchopt
    $ git clone https://github.com/benchopt/benchmark_tv_2d
-   $ benchopt run benchmark_tv_2d
+   $ cd benchmark_tv_2d
+   $ benchopt install --config example_config.yml
+   $ benchopt run --config example_config.yml
 
-Apart from the problem, options can be passed to `benchopt run`, to restrict the benchmarks to some solvers or datasets, e.g.:
-
-.. code-block::
-
-	$ benchopt run benchmark_tv_2d --config benchmark_tv_2d/example_config.yml
-
-
-Use `benchopt run -h` for more details about these options, or visit https://benchopt.github.io/api.html.
+To run the benchmark on a limited subset of Objectives, Solvers or Datasets, visit https://benchopt.github.io/api.html or use the command ```benchopt run -h``.
