+# Forms
+
+A showcase page that demonstrates how to use the otter forms feature inside an application.
+
+The page contains both a step by step explanation to guide the users as well as a sample component that can be used as a reference and that illustrates the capabilities of the feature.

+    <div>
+      <p>This module provides utilities to enhance the build of Angular reactive forms for specific use cases, including:</p>
+      <ul>
+        <li>A container/presenter structure for components</li>
+        <li>Handling form submission at page (or parent component) level</li>
+        <li>Displaying the error message outside the form</li>
+      </ul>
+    </div>
+
+    <h2 id="forms-example">Example</h2>
+    <div>
+      <p>
+        In the following example, we have a parent component with two subcomponents, each containing a form.
+      </p>
+      <p>
+        The first form requires the user to define their personal information (name and date of birth).
+        The second form requires the definition of the user's emergency contact information (name, phone number, and email address).
+        Both forms contain validators, such as certain fields being required or specific values having to follow a certain pattern.
+      </p>
+      <p>
+        The submit of both forms is triggered at parent component level.
+      </p>
+      <o3r-forms-pres></o3r-forms-pres>
