+# Linking the new class to the module
+Now that the axes class is created we just need to link it to the module.
+To do so you need to add the following line in `mymodule/myAxes/__init__.py`
+```python
+from axMyFirstAxes import AxMyFirstAxes
+```
+
+the module `mymodule` import by default all axes in the sub-module `myAxes`, so you just need
