# Example config:

#
# Run `lychee . --dump` to list all found links that are being checked.
#
# Note that by default lychee will only check markdown and html files,
# to check any other files you have to point to them explicitly, e.g.:
# `lychee **/*.rs`.
#
# This unfortunately doesn't list anything for non-glob checks.
