+## syntaxe aemark
+
+Le site AE utilise markdown pour le rendu de la plupart
+des textes saisis par les utilisateurs.
+Cependant, la syntaxe utilisée n'est pas celle officielle
+telle que définie par John Gruber,
+mais est basée sur [CommonMark](https://commonmark.org/),
+avec quelques variations pour les usages particuliers du site AE.
+
+Les deux principaux ajouts sont :
+
+- Les urls commençant par `page://` sont modifiées pour commencer par `/page/`
+- Des modificateurs de taille peuvent être indiqués directement dans la source
+  d'une image
+
+Les variations d'aemark sont documentées sur
+[le site AE](https://ae.utbm.fr/page/Aide_sur_la_syntaxe/).
+
+Le code est hébergé sur le dépôt Git [aemark](https://github.com/ae-utbm/ae-markdown).
+
+## Utiliser aemark
+
+Le code du parser aemark est écrit en Rust dans une librairie
+indépendante, avec des bindings vers différents langages.
+Les librairies mises à disposition exposent une seule fonction,
+qui prend simplement du markdown en entrée et renvoie l'HTML correspondant.
+
+Les librairies pour les différents langages sont toutes
+basées sur le même code Rust.
+La seule différence entre chacune tient uniquement dans la manière
+d'intégrer ce code dans les bindings.
+De cette manière, le comportement est assuré d'être le même
+sur toutes les plateformes disponibles, avec en prime des performances
+respectables.

+
+=== ":simple-python: Python"
+
+    ```python
+    from aemark import markdown
+
+    result = markdown("this is some *markdown text* with __formatting__")

+
