README > Installation : "--parent" argument of mkdir does not exist on macOS

[MTindev]

Bug report

Hello,

In the README file, in the section Documentation > Installation, it is expected that the given commands make it easy to perform the installation.

However, in macOS, the --parent argument does not exist for the mkdir command. Only the -p argument exists.

Code snippet that reproduces the problem

$ mkdir --parents tools/php-cs-fixer

# returns :
mkdir: illegal option -- -
usage: mkdir [-pv] [-m mode] directory_name ...

What is expected ?

To facilitate the process on all platforms (and avoid an error on macOS), I suggest :

mkdir -p tools/php-cs-fixer
