 There are two primary uses for dynamic blocks:
 
 1. Blocks where content should change even if a post has not been updated. One example from WordPress itself is the Latest Posts block. This block will update everywhere it is used when a new post is published.
-2. Blocks where updates to the code (HTML, CSS, JS) should be immediately shown on the front end of the website. For example, if you update the structure of a block by adding a new class, adding an HTML element, or changing the layout in any other way, using a dynamic block ensures those changes are applied immediately on all occurrences of that block across the site. (If a dynamic block is not used then when block code is updated Guterberg's [validation process](/docs/reference-guides/block-api/block-edit-save.md#validation) generally applies, causing users to see the validation message, "This block appears to have been modified externally").

 For many dynamic blocks, the `save` callback function should be returned as `null`, which tells the editor to save only the [block attributes](/docs/reference-guides/block-api/block-attributes.md) to the database. These attributes are then passed into the server-side rendering callback, so you can decide how to display the block on the front end of your site. When you return `null`, the editor will skip the block markup validation process, avoiding issues with frequently-changing markup.

 _This package assumes that your code will run in an **ES2015+** environment. If you're using an environment that has limited or no support for ES2015+ such as IE browsers then using [core-js](https://github.com/zloirock/core-js) will add polyfills for these methods._
 
+## Technical implementation details
+
+The new Widgets Customizer replaces `Appearance > Customize > Widgets` with block-based editors. The original Customizer is a Backbone app, but the new editor is a React app. One of the challenges is to integrate them together but make sure features from both sides still work.
+
+We extend the Customizer's sections and controls in the `/controls` directory and inject some custom logic for the editor. We use React portal to render each editor in its section to reuse most of the styles and scripts provided by the Customizer.
+
+`components/sidebar-block-editor` is the entry point for each widget area's block editor. `component/sidebar-block-editor/sidebar-adapter.js` is an adapter to talk to [the Customize API](https://developer.wordpress.org/themes/customize-api/) and transform widget objects into widget instances. 
+
+`components/sidebar-block-editor/use-sidebar-block-editor.js` is a custom React Hook to integrate the adapter into React and handle most of the translations between blocks and widgets. These allow us to implement basic editing features as well as real-time preview in a backwards-compatible way.
+
+Whenever the blocks change, we run through each block to determine if there are created, edited, or deleted blocks. We then convert them to their widget counterparts and call the Customize API to update them. 
+
+For React developers, this can be thought of as a custom reconciler or a custom renderer for the Customizer. But instead of targeting DOM as the render target, we are targeting WordPress widgets using the Customize API.
+
+This is not the typical way the block editor is intended to be used. As a result, we have to also implement some missing features such as undo/redo and custom focus control. It is still a goal to make the block editor as easy to integrate into different systems as possible, so the integration in the Widgets Customizer can be a good experience for us to reflect some drawbacks in our current API and potentially improve them in the future.
