When to add salt to homemade pinto beans?

I heard you're not supposed to add salt until they're soft because if you add if before the salt won't let them get soft..

Answer

The mexican way lol.. Salt, garlic and onions add right away. They will cook just fine.

Add salt before and let them cook they will get soft...
