How to Get Started Learning Ur/Web

One suggestion: start with the main demo linked below, jumping to the official tutorial as you feel more curious about details of the language. Much of the reference manual is oriented toward readers with training in formal semantics, so most readers will never want to read it cover-to-cover; but the sections on command-line arguments and so forth are worth skimming for everyone.
