+
+### Media
+
+You can place an image on your card using the `HvCardMedia` component. It will adapt to the location of the card it is placed on.
+
+```jsx live
+<HvCard className="w-240px" bgcolor="atmo1">
+  <HvCardMedia
+    component="img"
+    alt="Schedule New Job"
+    height={120}
+    image="https://s7d9.scene7.com/is/image/hitachivantara/take-charge-of-your-hybrid-cloud-estate-everflex-control-square:mediumvertical?fmt=webp"
+  />
+  <HvCardContent>
+    <HvTypography>
+      Use the live code editor to change the position of the `HvCardMedia`
+      component in the card.
+    </HvTypography>
+  </HvCardContent>
+</HvCard>
+```
+
+### Actions
+
+If you want to add actions to the card, you can use the `HvActionBar` component.
+
+```jsx live
+<>
+  <HvCard className="w-380px" bgcolor="atmo1">
+    <HvCardHeader
+      title={
+        <HvTypography variant="title3">Start using UI Kit now</HvTypography>
+      }
+      subheader={
+        <HvTypography>
+          Get started with the Hitachi Vantara UI Kit and build your next
+          project.
+        </HvTypography>
+      }
+    />
+    <HvActionBar className="flex-1">
+      <HvButton startIcon={<Code />} variant="primarySubtle">
+        Github
+      </HvButton>
+      <div aria-hidden className="flex-1" />
+      <HvButton startIcon={<Doc />}>Get Started</HvButton>
+    </HvActionBar>
+  </HvCard>
+</>
+```
+
+### Selectable
+
+You can mark a card as selectable by adding the `selectable` prop. The `selected` prop indicates whether or not the card is selected.
+
+```jsx live
+import { useState } from "react";
+
+export default function Demo() {
+  const [checked, setChecked] = useState(null);
+  const storages = [
+    {
+      name: "Local Storage",
+      icon: <Storage size="S" />,
+      description: "Use local storage for quick access to user settings.",
+    },
+    {
+      name: "Cloud Storage",
+      icon: <Cloud size="S" />,
+      description: "Use cloud storage for secure, scalable data access.",
+    },
+  ];
+
+  return (
+    <div className="flex flex-row gap-2 w-full">
+      {storages.map((p, idx) => {
+        return (

+                      }}
+                    />
+                  </div>
+                }
