+        A context manager that measures the elapsed time of a code block.
+
+        This class allows you to measure the time taken to execute
+        a block of code using the context management protocol.
+        It records the start time when entering the context and
+        the end time when exiting the context, allowing you to
+        calculate and print the elapsed time.
+
+        Attributes:
+            start_time (float): The time when the timer starts.
+            end_time (float): The time when the timer ends.
+
+        Example:
+            >>> with Timer() as timer:
+            ...     time.sleep(2)
+            ...
+            Elapsed time: 2.0000 seconds
