+You need to specify the calendar URL by pasting it into `calendar_url.txt` in this project directory.
+
+> To find the secret iCal URL for your Google Calendar, follow these steps:
+> 
+> Open Google Calendar in your web browser.
+> In the top right, click the Settings (gear icon) > Settings.
+> On the left sidebar, under "Settings for my calendars", click the name of the calendar you want to use.
+> Scroll down to the "Integrate calendar" section.
+> Look for the field "Secret address in iCal format".
+> Copy this URL (it should end in .ics).
