how to add 5 star rating to html page from schema.org?

hello,

i would like to implement 5 star rating system on my blog post, hopefully it will appear on google search result for every page and will result in more visitors to my site.

how can i do it as i have only html site and i cant use wordpress plugins? i would like to use it with schema but i havent seen any example how to do it simply by myself.

i also read on the web that it is recommended to put rating only on 1 or 2 pages of the site like a product page, but i have seen people...
