Merge branch 'amorsi/purr-data-readme-update'
Instead of copying the relevant information from https://github.com/agraef/purr-data/wiki/Installation#installing-from-the-jgu-repositories, why not just link there? The problem is that if that information ever becomes outdated, I'll update it in the wiki and we'll likely forget to update this README accordingly.
That sounds good to me. If you have time to make a merge request I'll merge it.
