+# Installation - from source
+One can install the package from source using the following command:
+```
+    python setup.py install
+```
+
+# A first practical example
+The easiest way to learn bionc is to dive into it.
+So let's build our first model.
+Please note that this tutorial is designed to recreate example which builds a lower limb model (Pelvis, Thigh, Shank, Foot).
+
+## The import
+The first step is to import the classes we will need.
+```python
+from bionc import (
+    AxisTemplate,
+    BiomechanicalModelTemplate,
+    MarkerTemplate,
+    SegmentTemplate,
+    NaturalSegmentTemplate,
+    C3dData,
+    BiomechanicalModel,
+    JointType,
+)
+```

 InertiaParameters need to be generated in SCS or in NSCS ? it can be both...
 
-model creation - on the way
-- from experimental data ? (see the template)
+model creation:
 - from biomod ?
 - from opensim ?
