 ## Installing the Python package
 The installer for any supported platform includes, among others, a Python package ('wheel');
 for instance, for Python 3.9, the package can be found under `python/3.9/wheel` folder.

-## Expanded simulation script
-
-As a first step towards writing sample and simulation specifications
-of your own, let us expand the simulation script
-[AlternatingLayers1.py]({{% ref-src "Examples/specular/AlternatingLayers1.py" %}})
-from the preceding pages.
-Instead of the shorthand calls to modules
-[std_samples]({{% ref-src "Wrap/Python/std_samples.py" %}}) and
-[std_simulations]({{% ref-src "Wrap/Python/std_simulations.py" %}}),
-we provide explicit code for the functions `get_sample` and `get_simulation`:
-{{< highlightfile file="Examples/specular/AlternatingLayers1.py">}}
-<p>
-
-### Sample
-
-`get_sample` is a function without arguments.
-It returns an object of type [MultiLayer]({{% ref-api "classMultiLayer" %}}).
-
-The return statement is preceded by three stances.
-Each stance starts with a comment line,
-{{< highlight python >}}
-    # comment extends from hash character to end of line
-{{< /highlight >}}
-
-BornAgain functions that start with a capital letter,
-like `MaterialBySLD` or `Layer` are _constructors_ or
-constructor-like global functions.
-They return new _objects_. An object is an instance of a _class_.
-The function `MaterialBySLD` instantiates an object of type
-[Material]({{% ref-api "classMaterial" %}})
-the function `Layer` an object of type
-[Layer]({{% ref-api "classLayer" %}}).
-
-Function like `addLayer` is a member function of class
-[MultiLayer]({{% ref-api "classMultiLayer" %}}).
-This can be seen from the two lines
-{{< highlight python >}}
-    sample = ba.MultiLayer()
-    sample.addLayer(ambient_layer)
-{{< /highlight >}}
-where `sample` is created as a new instance of class `MultiLayer`.
-
-### Simulation
-
-`get_simulation(sample, scan_size=500)` is a function with one
-required argument (`sample`) and one optional keyword argument
-(`scan_size`). If the function is called with only one argument,
-then `scan_size` is assigned the default value 500.
-
-`angstrom` and `deg` are numeric constants. They are used to
-convert physical quantities to internal units nanometer and radian.
-
-The function returns an object of type
-[SpecularSimulation]({{% ref-api "classSpecularSimulation" %}}).
