Haven't seen this syntax before, is it one string inside the values array? 🤔

I think you can do it this way too:

  set {
    name  = "installCRDs"
    value = true
  }

Yep this is the simplest way to set multiple values as one, you can essentially paste in YAML with variable interpolation. I think it's the most readable of the available options, especially with large charts that have lots of options!
