getting the right page as the homepage

hello. please could you help me. I have installed wordpress at http://www.epilepsy.technology/en/ but I was hoping for the site to appear at a directory further down., i.e. http://www.epilepsy.technology/
I guess I need to change the htaccess file, but this is currently sitting in the http://www.epilepsy.technology/en/ directory.

Can you tell me what I need to do to have my wordpress website visible at the url http://www.epilepsy.technology/

Many thanks
