-/// Represents an observable sequence of elements that have a common key.
+/// Represents an observable sequence of elements that share a common key.
+/// `GroupedObservable` is typically created by the `groupBy` operator.
+/// Each `GroupedObservable` instance represents a collection of elements
+/// that are grouped by a specific key.
+///
+/// Example usage:
+/// ```
+/// let observable = Observable.of("Apple", "Banana", "Apricot", "Blueberry", "Avocado")
+///
+/// let grouped = observable.groupBy { fruit in
+///     fruit.first! // Grouping by the first letter of each fruit
+/// }
+///
+/// _ = grouped.subscribe { group in
+///     print("Group: \(group.key)")
+///     _ = group.subscribe { event in
+///         print(event)
+///     }
+/// }
+/// ```
+/// This will print:
+/// ```
+/// Group: A
+/// next(Apple)
+/// next(Apricot)
+/// next(Avocado)
+/// Group: B
+/// next(Banana)
+/// next(Blueberry)
