+
+### `useClerk().status`
+Possible values for `useClerk().status` are:
+- `"loading"`: Set during initialization
+- `"error"`: Set when hotloading clerk-js failed or `Clerk.load()` failed
+- `"ready"`: Set when Clerk is fully operational
+- `"degraded"`: Set when Clerk is partially operational
+The computed value of `useClerk().loaded` is:
+
+- `true` when `useClerk().status` is either `"ready"` or `"degraded"`.
+- `false` when `useClerk().status` is `"loading"` or `"error"`.
+
+### `<ClerkFailed />`
+```tsx
+<ClerkLoaded>
+  <MyCustomSignInForm/>
+</ClerkLoaded>
+<ClerkFailed>
+  <ContactSupportBanner/>
+</ClerkFailed>
+```
+
+### `<ClerkDegraded />`
+```tsx
+<ClerkLoaded>
+  <MyCustomPasskeyRegistration/>
+  <ClerkDegraded>
+    We are experiencing issues, registering a passkey might fail. 
+  </ClerkDegraded>
+</ClerkLoaded>
