santiagobiali: I got further with that! I got this message:
Installing flarum/flarum (v0.1.0-beta.4)
[InvalidArgumentException]
Project directory ./ is not empty.
create-project [-s|--stability STABILITY] [--prefer-source] [--prefer-dist] [--repository-url REPOSITORY-URL] [--dev] [--no-dev] [--no-plugins] [--no-custom-installers] [--no-scripts] [--no-progress] [--keep-vcs] [--no-install] [--ignore-platform-reqs] [--] [<package>] [<directory>] [<version>]
I tried to move the composer installation around and even re-did the installation a few times and kept getting that message...
