-More specifically, you'll need Python 3.
-NumPy_ and SciPy_ are needed for the calculations.
-If you want to use the provided functions for plotting sound fields, you'll need
-Matplotlib_.
-However, since all results are provided as plain NumPy_ arrays, you should also

-Instead of installing all of the requirements separately, you should probably

 Installation
 ------------
 
-Once you have installed the above-mentioned dependencies, you can use pip_
-to download and install the latest release of the Sound Field Synthesis Toolbox
-with a single command::
+First, create a new directory wherever you want, change into it, then run::
+
+    uv venv
 
-    python3 -m pip install sfs --user
+This will print instructions for how to `activate the environment`__.
+You should do that now!
 
-If you want to install it system-wide for all users (assuming you have the
-necessary rights), you can just drop the ``--user`` option.
+__ https://docs.astral.sh/uv/pip/environments/#using-a-virtual-environment
 
-To un-install, use::
+The Sound Field Synthesis Toolbox can be installed with::
 
-    python3 -m pip uninstall sfs
+    uv pip install sfs
+
+This will automatically install the NumPy_ and SciPy_ libraries as well,
+which are needed by the SFS Toolbox.
+
+If you want to use the provided functions for plotting sound fields, you'll need
+Matplotlib_::
+
+    uv pip install matplotlib
+
+However, since all results are provided as plain NumPy_ arrays, you should also
+be able to use any other plotting library of your choice to visualize the sound
+fields.
+
+The steps above need to be executed only once.
+Whenever you come back to this directory at a later time,
+you just need to activate the environment again.
 
 If you want to install the latest development version of the SFS Toolbox, have a
 look at :doc:`contributing`.
