+# Logo Slot
+
+### Slot ID: `logo_slot`
+
+## Description
+
+This slot is used to replace/modify/hide the logo.
+
+## Examples
+
+### Modify URL
+
+The following `env.config.jsx` will modify the link href for the logo.
+
+```jsx
+import { PLUGIN_OPERATIONS } from '@openedx/frontend-plugin-framework';
+
+const modifyLogoHref = ( widget ) => {
+  widget.content.href = "https://openedx.org/";
+  return widget;
+};
+
+const config = {
+  pluginSlots: {
+    logo_slot: {
+      keepDefault: true,
+      plugins: [
+        {
+          op: PLUGIN_OPERATIONS.Modify,
+          widgetId: 'default_contents',
+          fn: modifyLogoHref,
+        },
+      ]
+    },
+  },
+}
+
+export default config;
+```
+
+### Custom Component
+
+The following `env.config.jsx` will replace the logo entirely (in this case with a centered 🗺️ `h1`)
+
+```jsx
+import { DIRECT_PLUGIN, PLUGIN_OPERATIONS } from '@openedx/frontend-plugin-framework';
+
+const config = {
+  pluginSlots: {
+    logo_slot: {
+      keepDefault: false,
+      plugins: [
+        {
+          op: PLUGIN_OPERATIONS.Insert,
+          widget: {
+            id: 'custom_logo_component',
+            type: DIRECT_PLUGIN,
+            RenderWidget: () => (
+              <h1 style={{textAlign: 'center'}}>🗺️</h1>
