how to add more fields for processwire's user ?

[adrianmak]

processwire out of the box, a user with only username, email address, password and roles.

I'm going to create a user registration form, how to add more fields on the basic user object ? like gender, telephone, twitter account, and so on.

Put it simple, could I extend processwire users with more fields ?

Since users are pages with a certain template, you can access them after going to /setup/template/, choose Filters and set "Show System templates" to yes. From that point on you can add fields to users like on any other template.
