What parts of torah to study on Shavuot?

I grew up secular but am currently trying to incorporate more religion into my life. So I want to take the opportunity this year and follow the tradition of studying torah during the first night of Shavuot. However I don’t know which parts I should study (I don’t have a synagogue in walking distance that I could attend courses at so will be staying at home). Is this a good a good resource? https://www.chabad.org/library/article_cdo/aid/4757775/jewish/Traditional-Tikkun-Leil-Shavuot-Text.htm

Are these the “canonical” parts of torah that everyone reads on Shavuot, more or less? Or are there other or better texts for studying that you could recommend that are freely available?
