 Example Material() usage
 ========================
 
-Usage - basic Material()
-------------------------
-
-Here is an example that accesses a material from the internal collection called eurofer which has about 60 isotopes and a density of 7.78g/cm3.
-
-.. code-block:: python
-
-   import neutronics_material_maker as nmm
-
-   my_mat = nmm.Material('eurofer')
-
-Once the object has been initiated the OpenMC or Serpent material card can be accessed.
-
-.. code-block:: python
-
-   my_mat.openmc_material
-   my_mat.serpent_material
-
-To access MCNP material it is necessary to also provide an id.
-
-.. code-block:: python
-
-   my_mat = nmm.Material('eurofer', material_id=1)
-   my_mat.mcnp_material
-
-To access the Fispact material it is necessary to also provide a volume.
-
-.. code-block:: python
-
-   my_mat = nmm.Material('eurofer', volume_in_cm3=10)
-   my_mat.fispact_material
-
-To access the Shift material it is necessary to also provide a temperature and
-a material id
-
-.. code-block:: python
-
-   my_mat = nmm.Material('eurofer', temperature=293, material_id=1)
-   my_mat.shift_material
-
-
-Usage - hot pressurised  Material()
------------------------------------
-
-For several materials within the collection the temperature and the pressure impacts the density of the material. The neutronics_material_maker adjusts the density to take temperature (in C or K) and the pressure into account when appropriate. Densities are calculated either by a material specific formula (for example `FLiBe <https://github.com/ukaea/neutronics_material_maker/blob/openmc_version/neutronics_material_maker/data/multiplier_and_breeder_materials.json>`_) or using `CoolProps <https://pypi.org/project/CoolProp/>`_ (for example coolants such as H2O).
-
-.. code-block:: python
-
-    import neutronics_material_maker as nmm
-
-    my_mat1 = nmm.Material('H2O', temperature=300, pressure=15e6)
-
-    my_mat1.openmc_material
-
-Temperature can be provided in degrees C or Kelvin.
-
-.. code-block:: python
-
-    import neutronics_material_maker as nmm
-
-    my_mat1 = nmm.Material('H2O', temperature=573.15, pressure=15e6)
-
-    my_mat1.openmc_material
-
-The temperature is automatically sent to the openmc_material and
-serpent_material cards. However if this causes difficulties for you (perhaps
-due to not having cross sections at that temperature) this automatic propagate
-of temperature information can be disabled by setting the 
-temperature_to_neutronics_code to False.
-
-
-Usage - enriched Material()
----------------------------
-
-For several materials within the collection the density is adjusted when the material is enriched. For breeder blankets in fusion it is common to enrich the lithium 6 content.
-
-Lithium ceramics used in fusion breeder blankets often contain enriched lithium-6 content. This slight change in density is accounted for by the neutronics_material_maker.
-
-.. code-block:: python
-
-    import neutronics_material_maker as nmm
-
-    my_mat2 = nmm.Material('Li4SiO4', enrichment=60)
-
-    my_mat2.openmc_material
-
-
-The default enrichment target for 'Li4SiO4' is Li6 but this can be changed if required.
-
-.. code-block:: python
-
-    import neutronics_material_maker as nmm
-
-    my_mat2 = nmm.Material('Li4SiO4', enrichment_target='Li7', enrichment=40)

-Usage - adding extra lines to a material card
----------------------------------------------
-
-If you require additional lines at the end of the MCNP, Serpent, Fispact or
-Shift materia card then the additional_end_lines argument can be used. This
-will add specific line(s) to the end of a material card. Multiple lines can be
-added by creating a list with multiple entries.
-
-In this example and additional line can be added to allow the S(α,β) treatment
-of water to be correctly modeled in MCNP. But this could also be used to add
-comments to the material card or other text at the end of the material card
-string.
-
-.. code-block:: python
-
-    import neutronics_material_maker as nmm
-
-    my_mat2 = nmm.Material(

-The above code will return a MCNP material card string with the additional line
-'      mt24 lwtr.01' at the end. Notice that spaces should also be set by the
-user.
