+    """Pure implementation of the bogosort algorithm in Python.
+    Bogosort generates random permutations until it guesses the correct one.
+
+    More info on: https://en.wikipedia.org/wiki/Bogosort
+    Args:
+        collection (List[int]): A mutable ordered collection with comparable items.
+    Returns:
+        List[int]: The same collection ordered by ascending.
+    Examples:
+    >>> bogo_sort([0, 5, 3, 2, 2])
+    [0, 2, 2, 3, 5]
+    >>> bogo_sort([])
+    []
+    >>> bogo_sort([-2, -5, -45])
+    [-45, -5, -2]
+    Raises:
+        ValueError: If the input is not a list of integers.
+    Note:
+        This is not an efficient sorting algorithm and is mainly used for educational purposes.
