when you run the code you will face this menu:
if you go through "write a new note" you'll face this:
as you can see, you should write your note title
and your note content
then your note will be created in "notes" folder with .json format
if you go through "read a note" you'll fave this:
then you should pick a file and then you can see it's details
if you go through "edit a note" you'll face this:
and again you should pick a note then you can add text to it
finally, if you choose "exit" the code process will be finished
