Where should I put school info?

Hi, I am a Taiwanese high school student applying to US colleges. My high school is not well-known outside of the country, so I was wondering where I should include my school profile, such as rigor or number of students who went to top universities. Would including a paragraph in my counselor recommendation letter be okay? Thanks!

To elaborate, my school did not show up on the SAT, ACT, or Coalition App school lists.
