 Clone and cd to root project then:
-$ poetry install
+`$ poetry install`
 
 Run:
-$`python main.py -v <yearday>` e.g: `python main.py -v 2201` '22' represent year 2022 and '01' is day 01. 
-For current year works with day only: `python main.py -v 01`
-For testing sample input add `-s s`: `python main.py -v 01 s- s`
+$`python main.py -v <yearday>` e.g: `python main.py -v 2201` '22' represent year 2022 and '01' is day 01.
 
+If no year is mentioned, it will be taken automatically last year available: `python main.py -v 01`. 
+In this case '22' is the last year available for 'day01'.
 
+Testing sample input add `-s s`: `python main.py -v 01 -s s`
