+Installation
+------------
+
+We load the necessary module:
+
+    .. code-block:: bash
+
+        module load gcc/9.3.0
+
+we download and unzip the source code from this repository, this file will help us to compile Calculix easier
+
+    .. code-block:: bash
+
+        mkdir calculix
+        cd calculix
+        wget https://codeload.github.com/calculix/ccx_prool/zip/refs/heads/master
+        unzip master
+
+We enter the folder and edit the makefile
+
+    .. code-block:: bash
+
+        cd ccx_prool-master
+        vim Makefile
+
+It should look like this, remember that in line 7 and 9 there must be version 2.21
+
+    .. image:: images/Makefile.png
+        :align: center
+        :alt: Makefile
+
+We can enter the Calculix folder and delete versions that we don't need, so that only 2.21 remains.
+
+    .. code-block:: bash
+
+        cd CalculiX
+        rm -r ccx_2.1* ccx_2.20 ccx_2.8p2 ccx_2.9
+        cd ..
+
+Now we compile
+
+    .. code-block:: bash
+
+        make
