Restarting WoW after 7 years, need help!

Hi All!

I used to play WoW on a different server 7-8 years back but decided to take a break and focus on my career and personal life.
Now that I'm in a good place and have a 3 month break before I start another phase of my hectic life I want to play the game again.
The last raid I played was Ulduar. After that I dont know much.
I dont even know from where to download the game and what addons to use.
Can someone here help me?

There's a download button at the top of the site ->select expansion->wrath of the lich king.Make an account here and log in with that account.Select realm:Lordaeron if you like 1x leveling rates and hardcore raid content ; Icecrown if you like fast-paced leveling(i think 5x or 7x?).Pvp is probably better on icecrown but there's alot of people with shadowmournes since you can buy 1 from the shop.Lordaeron has no shop.Progression is up to Trial of the Crusader , which is the raid after Ulduar.Icecrown Citadel will be opening after 16 days,which is the next raid.
