-A React Component that creates a subscription to the provided Observable once
-the component mounts, and unsubscribes when the component unmounts.
+A React Component that manages the subscription of its children's Observables.
 
-It also acts as a Suspense boundary, rendering a fallback element until the
-suspended element resolves.
+It will subscribe to all the observables used by its children before they get 
+mounted, and will unsubscribe from all of them once it unmounts.
+
+If given a fallback, it also acts as a Suspense boundary, rendering the fallback
+element until the suspended element resolves.
 
 ```tsx
 const Subscribe: React.FC<{
-  source$: Observable<any>
+  source$?: Observable<any>
   fallback?: JSX.Element
 }>
 ```
 
 #### Properties
 
-- `source$`: Source Observable that the Component will subscribe to.
+- `source$`: (Optional) Source Observable that the Component should subscribe to, before its children renders.
 - `fallback`: (Optional) The JSX Element to be rendered before the
   subscription is created. Default: `null`.

-This Component doesn't trigger any updates.

+:::note Important
+This Component first mounts itself rendering `null`, subscribes to `source$` and
+then it renders its children.

+- `keySelector?`: (Optional) A function that extracts the key from the emitted value.
