-
-> ![VIT Timetable Export Plugin - Academics Calendar view](images/academics-calendar-view-1.png)
-
-- Select the relevant semester and the correct Class Group
-  - The `Academics > Time table` page shows the Class Group in the 2nd column of the first table
-- Select **each** of the displayed months to display the calendar for that month and then click on the `Save` button for **each** one of them
-- Once **all** the months are selected and saved, clicking on the `View saved` button should show somthing like this:
-  - In the example below, academic calendar details for the months of 'July, August, September, October and November 2024' for the 'Fall Semester 2024-25' and 'General Freshers' class group are saved

 All of VTOP's content is dynamically generated.  There is a single URL `https://vtop.vit.ac.in/vtop/content` under which all content resides and the browser does not navigate to different pages for different sections.  The code to export the Timetable data needs to run on the `Time Table` page.  There are a few ways to achieve this, all of which require code to be injected as [Content Scripts](https://developer.chrome.com/docs/extensions/develop/concepts/content-scripts#capabilities) and run:
