The document summarizes a Housing First Guide for Europe produced by FEANTSA, the European Federation of National Organisations working with the Homeless. It was a 2-year project funded by the Stavros Niarchos Foundation. The Guide was created with an advisory board of European housing experts and is aimed at service providers and policymakers. It consists of 6 online units covering the principles and practice of Housing First in Europe. FEANTSA hopes the Guide will help spread knowledge of Housing First and support its implementation across the continent.
