To set yourself up for contributing to Fortran index in one of the hackathons,
provide your GitHub username to one of the organisers, who will add you to the
fortran-index GitHub organisation. Once you've been added, you will be able to
clone the
fortran-lang-webpage
fork of
https://github.com/fortran-lang/webpage.
Beware that a straightforward clone of this fork will pull the entire Git history of the website, which is more than 50 GB. Instead, clone using
git clone --filter=blob:none git@github.com:fortran-index/fortran-lang-webpage.git
or
git clone --depth=1 git@github.com:fortran-index/fortran-lang-webpage.git
