Ironically, according to my experience, the .well-known directory doesn’t do justice to its name. Even in use cases that would fit nicely in its original purpose. But I’m getting a bit ahead of myself. Let’s first start with what it is, then move to discuss where it’s used. But we’ll do this rapidly, otherwise this […]
