How to register for codewars?

Question

ruby

Just started learning Ruby. There are no tasks at all in the books to consolidate the material. I found codewars.com, tried it in incognito mode, liked it, decided to register and... ran into a problem. I can't figure out how to register there. It is clear that you need to enter your data in the code, but the site does not accept any of the options.
Please tell me what the code should look like.
I understand that "you need to solve a couple of problems." Please do NOT write about it. Better answer to the point. What do you need to write to register.
This is the code in the registration form:
class Person
def initialize(name)
@name = name
end
def greet(other_name)
"Hi #{other_name}, my name is #{name}"
end
end
PS: and yes, I'm a beginner and I'm not familiar with OOP yet.
