As software has gotten more complex over the last years, the importance of declaring licensing information has become even more crucial. The FSFE's REUSE initiative contributes to the goal of clearly displaying legal information in Free Software projects by embedding it into every file of the repository. Any project following the REUSE recommendations makes copyright and licensing information readable for both humans and machines. We ensure that individuals, organisations, and companies that are reusing code are aware of and respect the licence terms chosen by its original author, thus facilitating the communication of this legal information among everyone involved in the software supply chain.

REUSE integrates seamlessly into development processes and other best practices of indicating Free Software licences. In addition, there are tools and documentation to help you get started. During this talk, we will take you through the learnings of large projects becoming REUSE compliant (e.g. curl or GNUHealth) and present the latest features of our REUSE helper tool, which makes declaring license information a quick and fun endeavour.
