+* `/calendar view` : Once the authentication is successful, you can use this command to view the private events on your calendar. Events will be displayed with title, date, start time and end time. You will also get the link, which you can click on and it will take directly to your calendar where you can udpate or delete that event.
+
+* `/calendar create "Title" "Date" "Start time" "Endtime"` : This command can be used to create a private on your primary calendar, where Title is the title of the event you are creating, and date should be in format YYYY-MM-DD and time in 24 hours format.
+
+* `/calendar logout` : Once you are done with viewing, creating your calendar events and wants to log out of the gmail account, use this command and it will log you out and redirect to your home page.
