 # Block Editor Handbook
 
-Hi! 👋 Welcome to the Block Editor Handbook.

-The [**Block editor**](https://wordpress.org/gutenberg/) is a modern and up-to-date paradigm for WordPress site building and publishing. It uses a modular system of **Blocks** to compose and format content, and is designed to create rich and flexible layouts for websites and digital products.

-Through the Block editor, you create content modularly using Blocks. There are a number of [core blocks](https://developer.wordpress.org/block-editor/reference-guides/core-blocks/) ready to be used, and you can also [create your own custom block](https://developer.wordpress.org/block-editor/getting-started/create-block/).

-A [Block](https://developer.wordpress.org/block-editor/explanations/architecture/key-concepts/#blocks) is a discrete element such as a Paragraph, Heading, Media element, or Embed. Each block is treated as a separate element with individual editing and format controls. When all these components are pieced together, they make up the content that is then [stored in the WordPress database](https://developer.wordpress.org/block-editor/explanations/architecture/data-flow/#serialization-and-parsing).

 ## Navigating this handbook
 
 This handbook is focused on block development and is divided into five sections, each serving a different purpose.
 
 
-**[Getting Started](https://developer.wordpress.org/block-editor/getting-started/)**
+- [**Getting Started**](https://developer.wordpress.org/block-editor/getting-started/) - For those just starting out with block development, this is where you can get set up with a [development environment](https://developer.wordpress.org/block-editor/getting-started/devenv/) and learn the [fundamentals of block development](https://developer.wordpress.org/block-editor/getting-started/create-block/). Its [Glossary of terms](https://developer.wordpress.org/block-editor/getting-started/glossary/) and [FAQs](https://developer.wordpress.org/block-editor/getting-started/faq/) should answer any outstanding questions you may have.
