How to build credit score without a job

I've been a stay at home mom since I was 18 I'm now 20 and my credit score is still 0. Me and my husband have been blessed enough for me to stay home and take care of our babies. We have been looking into getting a loan to buy a modular home but I have no income of my own so it's hard to get a credit card to build credit. And his is good but we want it in both of our names. And we both need a score to get the loan.

So how can you get a credit card without your own income? Do I just lie and say it's how much he makes since we share? Or what?

Of course I will be able to pay off my credit cards and stuff but I don't know how or through who to get one 😭
