+A word about numbering, implementation and sustainability over time of this repository:
+This project is born with the Debian 7 distribution in 2016. Over time, CIS Benchmark PDF
+has evolved, changing it's numbering, deleting obsolete checks.
+In order to keep retro-compatiblity with the last maintained Debian, the numbering
+has not been changed along with the PDF, because the configuration scripts are named after it.
+Changing the numbering might break automation for admins using it for years, and handling
+this issue without breaking anything would require a huge refactoring.
+As a consequence, please do not worry about numbering, the checks are there,
+but the numbering accross PDFs might differ.
+Please also note that all the check inside CIS Benchmark PDF might not be implemented
+in this set of scripts.
+We did choose the most relevant to us at OVHcloud, do not hesitate to make a
+Pull Request in order to add the missing script you might find relevant for you.
