--- 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. # Config notes Domain | Object | Recommendations -------------------- | ---------- | ---------------------------------- Hardware-Integrity-1 | Bootloader | Must control bootloader integrity.
