+**BREAKING**: The `NavLogoBlueprint` has been removed and replaced by `NavContentBlueprint`, which instead replaces the entire navbar. The default navbar has also been switched to a more minimal implementation.
+
+To use `NavContentBlueprint` to install new logos, you can use it as follows:
+
+```tsx
+NavContentBlueprint.make({
+  params: {
+    component: ({ items }) => {
+      return compatWrapper(
+        <Sidebar>
+          <SidebarLogo />
+
+          {/* Other sidebar content */}
+
+          <SidebarScrollWrapper>
+            {items.map((item, index) => (
+              <SidebarItem {...item} key={index} />
+            ))}
+          </SidebarScrollWrapper>
+
+          {/* Other sidebar content */}
+        </Sidebar>,
+      );
+    },
+  },
+});
+```
