+title: "The documentation describes all integration configuration options"
+---
+
+## Reasoning
+
+Integrations can provide an options flow to allow users to change integration configuration.
+This rule ensures that all configuration options are documented so that users can understand what each option does and how to use it.
+
+## Example implementation
+
+The following example is for an integration with multiple configuration options, using the `configuration_basic` tag.
+
+```markdown showLineNumbers
+## Configuration options
+
+The integration provides the following configuration options:
+
+{% configuration_basic %}
+Country code:
+  description: You can specify the country code (NL or BE) of the country to display on the camera.
+Timeframe:
+  description: Minutes to look ahead for precipitation forecast sensors (minimum 5, maximum 120).
+{% end configuration_basic %}
+
+```
+
+## Exceptions
+
+There are no exceptions to this rule.
