When changing titles, don't forget to update the ToC and link refs.

Yup, I totally agree with these thoughts. Specifying the limitation of the current support for fat JARs will offer a lot of clarity.

And please test the new ToC links after merging. (I made a mistake with the Jib config FAQ before, if you remember 😄)
