Hello, I´m completely new in this JOOMLA-Thing.

I chose the B2J Calendar because of the simple and nice Design
and because of its responsiveness.

Now I don´t know, what is K2 and: Do I need to have that K2-Thing to use B2J Calendar?

If I do not: How can I install the Calendar and place it on the Frontpage of my Website?

I know that´s a lot of questions! Thank You for your Help!!!
