+## Format du fichier `scaffold.yml`
+
+Le fichier `scaffold.yml` est au format [YAML](https://yaml.org/). C'est ce fichier qui permet de définir les données à injecter dans les modèles lors de la génération d'un nouveau projet avec la commande `scaffold from ...`.
+
+**Schéma**
+
+``` yaml
+# Version du format de fichier. Actuellement, la seule valeur possible est 1.
+version: 1
+
+# Liste des variables à injecter dans les modèles de fichier
+vars:
+    - <Var> 
+#   - <Var>...
+```
+
+## Types
+
+### `<Var>`
+
+Définition d'une variable injectable dans les modèles de fichier.
+
+**Schéma**
+
+```yaml
+# Type de la variable. Actuellement, la seul valeur possible est "string"
+type: "string"
+
+# Nom de la variable. C'est le nom qui permettra d'accéder à la valeur de la variable dans les modèles de fichiers.
+name: <string>
+
+# Description de la variable. C'est le texte qui sera affiché dans l'invite de commande au moment de la génération de l'arborescence de fichiers.
+description: <string>
+
+# Liste des contraintes appliquées à la valeur de la variable. La valeur est considérée comme invalide tant que l'ensemble des contraintes ne sont pas remplies.
+constraints: 
+    - <Constraint>
+#   - <Constraint>...
+```
+
+### `<Constraint>`
+
+Définition d'une contrainte appliquée à la valeur d'une variable.
+
+```yaml
+# Règle de validation à appliquer à la valeur entrée par l'utilisateur.
+rule: <Rule>
+
+# Message à afficher à l'utilisateur si la règle de validation concorde avec la valeur entrée par celui ci.
+message: <string>
+```
+
+**Exemple**
+
+```yaml
+# Règle validant que la valeur ne doit pas être vide.
+rule: Input == ""
+message: Cette valeur ne peut être vide.
+```
+
+### `<Rule>`
+
+Règle de validation d'une contrainte appliquée à une variable. 
+
+Ce n'est ni plus ni moins qu'une condition booléenne écrite avec la syntaxe proposée par la librairie [github.com/antonmedv/expr](https://github.com/antonmedv/expr/blob/master/docs/Language-Definition.md).
