+meta.title: CircuitPython - Custom File Systems
+meta.description: "Set of examples of custom file systems and block-level devices for CircuitPython that can be
+used for educational purposes and expanded upon."
+
+intro.title: Introduction
+intro.text.10: "The goal of this experiment was to try and give people a strong, clear, and documented starting point
+  for future experiments that may require virtual file systems and block-level devices on CircuitPython devices."
+intro.text.20: "For example, by using the blank examples, you can easily create a bootstrapping code and file system
+  that connects securely to a remote server and pulls code directly from it without ever having to touch the MCU's
+  flash storage."
+intro.text.30: "The second main advantage is that this project can serve as a robust educational tool."
+intro.text.31: "Due to the permissive nature of Python and CircuitPython's APIs, it lets people easily test out
+  different designs and mechanisms for their file systems without running the risk of corrupting unrelated data or
+  bricking their device."
+intro.text.32: "Additionally, it is possible to manipulate and add logging to many of the methods which allows you to
+  see and understand the inner workings of CircuitPython, filesystems and BLD devices themselves."

+meta.description: "Collection d'exemples de systèmes de fichiers personnalisés et de périphériques de bloc pour
+CircuitPython pouvant être utilisés à des fins éducatives ou d'autres développements."
+
+intro.title: Introduction
+intro.text.10: "Le but de cette expérience était de fournir un point de départ solide, clair et documenté pour
+  de futures expériences nécessitant des systèmes de fichiers virtuels, ou des périphériques de bloc sur
+  des appareils utilisant CircuitPython."
+intro.text.20: "Par exemple, en utilisant les exemples modèles, il est possible de créer facilement un code de
+  démarrage et un système de fichiers qui vont connecter de manière sécurisée à un serveur distant, et y récupérer
+  directement du code sans jamais avoir à toucher à la mémoire flash du MCU."
+intro.text.30: "Le deuxième avantage majeur est que ce projet peut servir d'outil éducatif."
+intro.text.31: "En effet, les APIs extrêmement permissives de Python et CircuitPython permettent à leurs
+  utilisateurs de tester facilement différents designs et mécanismes pour leurs systèmes de fichiers sans risquer
+  de corrompre des données ou de rendre leur appareil inutilisable."
+intro.text.32: "De plus, vous pouvez très facilement ajouter des messages de débogage et manipuler plusieurs
+  méthodes, ce qui permet de voir et de comprendre le fonctionnement interne de CircuitPython, des systèmes de
+  fichiers et des périphériques de bloc en eux-mêmes."
