title: Annexes
---

The first part resumed all the configurations you must implement without any
explications since all the explanations are given as and when in the document.

- The _config_ tag quickly identifies the configurations and the recommendations
  to take.

- The _note_ tag allows you to notify some additional details.

- The _todo_ tag shows the possible improvements.

The second one allows to visualize all the todo notes in order to have a global
vision of the possible improvements of the document.
