+# Desktop Username Slot
+
+### Slot ID: `desktop_username_slot`
+
+## Description
+
+This slot is used to replace/modify/hide the desktop username.
+
+## Examples
+
+### Modify Username
+
+The following `env.config.jsx` will modify the username (in this case replacing it with 🤠)
+
+![Screenshot of modified username](./images/desktop_username_modified.png)
+
+```jsx
+import { PLUGIN_OPERATIONS } from '@openedx/frontend-plugin-framework';
+
+const modifyUsername = ( widget ) => {
+  widget.content.username = "🤠";
+  return widget;
+};
+
+const config = {
+  pluginSlots: {
+    desktop_username_slot: {
+      keepDefault: true,
+      plugins: [
+        {
+          op: PLUGIN_OPERATIONS.Modify,
+          widgetId: 'default_contents',
+          fn: modifyUsername,
+        },
+      ]
+    },
+  },
+}
+
+export default config;
+```
+
+
+### Replace Username with Custom Component
+
+The following `env.config.jsx` will replace the items in the desktop username entirely (in this case with an svg circle)
+
+![Screenshot of replaced with custom component](./images/desktop_username_custom_component.png)
+
+```jsx
+import { DIRECT_PLUGIN, PLUGIN_OPERATIONS } from '@openedx/frontend-plugin-framework';
+
+const config = {
+  pluginSlots: {
+    desktop_username_slot: {
+      keepDefault: false,
+      plugins: [
+        {
+          op: PLUGIN_OPERATIONS.Insert,
+          widget: {
+            id: 'custom_username_component',
+            type: DIRECT_PLUGIN,
+            RenderWidget: () => (
+              <svg height="30" width="30">
+                <circle r="15" cx="15" cy="15" fill="purple" />
+              </svg>
+            ),
+          },
+        },
+      ]
+    },
+  },
+}
+
+export default config;
+```
+
+### Add Custom Components before and after Username
+
+The following `env.config.jsx` will place custom components before and after the desktop username (in this case 🖋️ and 🪄).
+
+![Screenshot of custom components before and after](./images/desktop_username_custom_components_before_after.png)
+
+```jsx
+import { DIRECT_PLUGIN, PLUGIN_OPERATIONS } from '@openedx/frontend-plugin-framework';
+
+const config = {
+  pluginSlots: {
+    desktop_username_slot: {
+      keepDefault: true,
+      plugins: [
+        {
+          op: PLUGIN_OPERATIONS.Insert,
+          widget: {
+            id: 'custom_before_username_component',
+            type: DIRECT_PLUGIN,
+            priority: 10,
+            RenderWidget: () => "🖋️",
+          },
+        },
+        {
+          op: PLUGIN_OPERATIONS.Insert,
+          widget: {
+            id: 'custom_after_username_component',
+            type: DIRECT_PLUGIN,
+            priority: 90,
+            RenderWidget: () => "🪄",
+          },
+        },
+      ]
+    },
+  },
+}
+
+export default config;
+```
