getting wordpress to be index.html

Hi everyone

I have just completed a long process of taking wordpress and embedding it into my existing page structure (see https://sales-training-consultants.co.uk/wordpress/ ). But I am not too sure how to get it to be my main page so that when someone types in https://sales-training-consultants.co.uk they get the wordpress page rather than index.html. I have set permanent links up and wordpress is all in /wordpress below the root directory. Secondly, I am keen to update the metatags on the individual posts, but where does wordpress hold the actual pages or data?
Any help gratefully received!
