+
+<PageDescription>
+
+The `<FeatureCard>` component takes the same props as the `<ResourceCard>` component (except for `aspectRatio`, this is fixed at `1:2` for the card), this component should not be used within `<Row>` or `<Column>` components as the grid is built in to the component already.
+
+</PageDescription>
+
+## Example
+
+<FeatureCard
+  subTitle="With subtitle"
+  title="Title"
+  actionIcon="arrowRight"
+  href="/"
+
+  color="dark"
+  >
+
+![demo image](/images/large-image.png)
+
+</FeatureCard>
+
+## Code
+
+```
+
+<FeatureCard
+  subTitle="With subtitle"
+  title="Title"
+  actionIcon="arrowRight"
+  href="/"
+  disabled
+  color="dark"
+  >
+
+![demo image](/images/large-image.png)
+
+</FeatureCard>
