Use recursive grep in the no-shell example

 option. This is helpful for very fast commands (< 5 ms) where the shell startup overhead correction would
 produce a significant amount of noise. Note that you cannot use shell syntax like `*` or `~` in this case.

 ### Pre-requisites
 
-Install [`uv`](https://docs.astral.sh/uv/getting-started/installation/) and run the
-commands above from this directory.
+To make these scripts work, you will need `numpy`, `matplotlib` and `scipy`.
 
-The scripts declare their dependencies using [PEP 723](https://peps.python.org/pep-0723/)
-inline script metadata. `uv run` automatically installs these dependencies in an
-isolated environment before running the script.
+If you have a Python package manager that understands [PEP-723](https://peps.python.org/pep-0723/)
+inline script requirements like [`uv`](https://github.com/astral-sh/uv) or [`pipx`](https://github.com/pypa/pipx),
+you can directly run the scripts using
+
+```bash
+uv run plot_whisker.py sleep.json
+```
+
+Otherwise, install the dependencies via your system package manager or using `pip`:
+
+```bash
+pip install numpy matplotlib scipy  # pip3, if you are using python3
+```
