 # Number
+
+The `number` type can be used to define variables that accept numeric input.
+
+## Basic
+
+Basic syntax for the `number` type:
+
+```yaml
+variables:
+  - name: Age
+    type: number # Set the type to number
+    description: Age of the person
+template: |-
+  You are {{ .Age }} years old.
+```
+
+## Validation
+
+### Minimum
+
+You can use the `min` property to define a minimum value for validation:
+
+```yaml
+variables:
+  - name: Age
+    type: number
+    min: 18 # only allow ages 18 and above
+    description: Age of the person
+template: |-
+  You are {{ .Age }} years old.
+```
+
+### Maximum
+
+You can use the `max` property to define a maximum value for validation:
+
+```yaml
+variables:
+  - name: Age
+    type: number
+    max: 99 # only allow ages 99 and below
+    description: Age of the person
+template: |-
+  You are {{ .Age }} years old.
+```
