Where to upload and install

hi all

till date i did not view other threads in xenforo, only pre-sale questions. Coz i believe in xenforo, (digital point moved to xenforo - my main reason to choose xenforo)

Today my question is, I want my main site be


and the forum in www.mysite.com/forum

What i will be doing is, i will add a redirect in the site root( www.mysite.com) to go to forum(www.mysite.com/forum). In the future, i want to include variety of features in the root site.

So, now where do i have to upload the xenforo files

1. in the root and add in settings the forum url to be www.mysite.com/forum/

2. Or upload directly int /forum folder

How shall i pull the forum css to the main site, so the design is consistent.
