+"""Pancake Sort Algorithm Implementation.
+
+A pure Python implementation of the Pancake Sort algorithm.
+Pancake sort is a sorting algorithm that sorts an array by repeatedly flipping
+subsections of the array, similar to how you might sort a stack of pancakes
+by inserting a spatula and flipping the top portion.
+
+The algorithm works by finding the maximum element, flipping it to the top,
+then flipping it down to its correct position. This process is repeated for
+the remaining unsorted portion.
+
+Time Complexity: O(n^2) - We perform n iterations, each with up to 2 flips
+Space Complexity: O(1) - In-place sorting, only uses a constant amount of extra space
 
 For doctests run following command:
-python3 -m doctest -v pancake_sort.py
+    python3 -m doctest -v pancake_sort.py
 or
-python -m doctest -v pancake_sort.py
+    python -m doctest -v pancake_sort.py
 For manual testing run:
-python pancake_sort.py
+    python pancake_sort.py
