 **[Tutorial](https://reactjs.org/tutorial/tutorial.html)** is relatively informal, and is designed for people who prefer a hands-on approach to learning, and can tolerate skipping theory in favor of practice. Its goal is to give the reader a feel for a typical React workflow rather than to explain fundamentals in detail. Here we focus on *what* to do and spend less time on *how* or *why* we did it. It is extremely important to do a lot of hand-holding and unambiguously describe every single change. It should be possible for a beginner to mechanically follow every instruction, and still get to a working tic-tac-toe game.
 
-**[Quick Start](https://reactjs.org/docs/hello-world.html)** is designed to introduce fundamental concepts in a step-by-step way. Each individual article in Quick Start builds on the knowledge from the previous ones, so make sure not to add any "cyclical dependencies" between them. It is important that the reader can start with the first article and work their way to the last Quick Start article without ever having to "look ahead" for a definition. This explains some ordering choices (e.g. that state is explained before events, or that "thinking in React" doesn't use refs). Quick Start also serves as a reference manual for React concepts, so it is important to be very strict about their definitions and relationships between them. This is, for example, why we introduce elements before components.

They intentionally don't cover all corner cases, and focus on establishing firm foundations.
 
 **[Advanced Guides](https://reactjs.org/docs/jsx-in-depth.html)** are deep dives into topics that aren't essential for a beginner developer but that everyone bumps into sooner or later. They don't have a specific order, and target more experienced developers. If you have a set of recipes fitting a particular use case, and those recipes aren't opinionated (most React users would agree on them), this is the place to add them.
