Kobo ePUB Guidelines

Hi All,
I'm planning to launch eBooks in Kobo site. I'm going to create ePUB formats for these books.
Is there any KOBO guidelines available to create an ePUB file specifying the DO's and DON't's?
Because AMAZON provides a Kindle Publishing Guidelines for the same purpose.
Can you please share any guidelines released by KOBO that are to be used in the ePUB which is supported on Kobo?
