Welcome on Ashes of Phoenix !
As Myakot said if you never played any Fonline game before you should take a look at the beginner guide on the wiki. It is wip and for to be complete but it is a start.
You can also read game general description and fag on
this page, find a lot of usefull information on the
wiki or here on the forum ( but it's not easy to find information here ).
Once ingame you will quickly have to choose a faction. I think you could find help from other player of your faction ( you will meet them at your faction headquarters ).
