Hi himansh,
The main things to remember when setting up an account is to download the software through PokerStrategy.com's download link and input the PokerStrategy.com bonus code when necessary. This is vital to ensure that your new account is fully tracked and you can then enjoy all of the benefits that it brings
PokerStrategy.com provide a helpful download guide for each of it's partner poker rooms, just let us know which room you're considering and we'll link you to the guide.
Occasionally an ID check is required when setting up your account. This is a one-off, very straight forward process and there for your own protection. It is more common for this to be done when you look to make your first withdrawal.
Can't think of anything else at the moment, other than have a read of the poker room's terms and conditions when signing up to. These again are important and there for your protection as well as the poker room.
If there's anything else you're unsure of, just let us know and we'll try to help out.
Good luck and enjoy your poker,
Bart
