add thumbnail/description PAGE in front of posts

I’ve started a new blog DRIVING MISS SHARI to profit from my misfortunate accident that has deprived me of driving privileges.

My main blog SHARISAX IS OUT THERE https://sharisax.com has a Front Page that gives thumbnails and brief descriptions of the articles.

How do I set that up for the new blog: https://sharisax.com/DrivingMissShari

Thanks,
Shari
