$updatedField

Specifies which database field should use for keep data record update timestamp. Leave it empty to avoid update it (even useTimestamps is enabled)

Just a minor one.
Reads like an Inuit wrote it.
I'm not 'scanning' the docs now for typos or serious errors.
But I stumbled already about something more serious.

In particular you should point out more the difference between the builder class and the model's member functions.
