/**
 * A value is going to be part of the form in the FE of the OS.
 * Something like a boolean, a string, a number, etc.
 * in the fe it will ask for the name of value, and use the rest of the value to determine how to render it.
 * While writing with a value, you will start with `Value.` then let the IDE suggest the rest.
 * for things like string, the options are going to be in {}.
 * Keep an eye out for another config builder types as params.
 * Note, usually this is going to be used in a `Config` {@link Config} builder.
