X-Git-Tag: v0.25.0~1^2~8
X-Git-Url: http://source.bookstackapp.com/bookstack/commitdiff_plain/456afdcd4c9a724ad50b4bddbe4812ccccd9606a?ds=inline;hp=--cc

Updated configuration files

Added a notice to the top of each to explain they should not be normally modified.
Standardised comment format used for each item.
Better aligned some files with laravel 5.5 options.
