...You host it yourself, wherever you want (Netlify, Github Pages...), you're in control. Previously the recommended way to install Photo Stream was to fork the repository. In my opinion, this was not really optimal and being a fan of Docker I began working on optimizations to run Photo Stream in a container. That's why configuration has been moved from _config.yml to .env so when switching from the initial repo you will have to set up the .env file accordingly.
