+### Working with TimerManager
+
+The TimerManager class is designed to track the execution time of code. It allows you to obtain the total runtime in various formats.
+
+```py
+from ipars import TimerManager
+
+t = TimerManager()
+```
+
+### Brief Overview of TimerManager Methods
+
+1. The **start** method marks the starting point of the time measurement.
+
+2. The **end** method marks the endpoint of the time measurement.
+
+3. The **getWorkTime** method returns the total execution time in the specified format. Supported formats are seconds, minutes, and hours. The ndigits parameter specifies the number of decimal places for rounding; by default, the number is not rounded.
+
+### Example of Using TimerManager
+
+```py
+from time import sleep
+from ipars import TimerManager
+t = TimerManager()
+
+# Starting the timer
+t.start()
+sleep(2) # simulating two seconds of work
+t.end()
+
+# Displaying results in different formats
+print(f"Execution time in seconds: {t.getWorkTime()}") # 2.0008320808410645
+print(f"Execution time in minutes: {t.getWorkTime(ndigits=2, format='minutes')}") # 0.03
+print(f"Execution time in hours: {t.getWorkTime(ndigits=4, format='hours')}") # 0.0006
+```
