#Guide

These documents introduce hd-lang from complementary perspectives:

Take the tour: one claim per page, with a program you run and change in the browser.
Keep Learn hd-lang in 10 Minutes at hand: the syntax on one page, with examples that parse.
Read the Language Overview for the language's purpose, priorities, and core conceptual model.
For everyday jobs — JSON config, doc tests, timeouts and retries, files, log scanning, wiring a program in main, and packages — read Working With Data.
For the commands day to day, read The hd Command.
Read Use Scenarios for the product needs and workflows that shape the design.

For normative syntax and semantics, use the formal specification. Deferred and exploratory work is collected under Future Work.
