 # Jetpack Block Editor Extensions
 
-This directory lists extensions for the Block Editor, also known as Gutenberg,
-[that was introduced in WordPress 5.0](https://wordpress.org/news/2018/12/bebo/).
+This directory lists extensions for the Block Editor, also known as Gutenberg, [that was introduced in WordPress 5.0](https://wordpress.org/news/2018/12/bebo/).
 
 ## Extension Type
 
 We define different types of block editor extensions:
 
-- Blocks are available in the editor itself.
-- Plugins are available in the Jetpack sidebar that appears on the right side of the block editor.
+- Blocks are available in the editor itself, and live in the `blocks` directory.
+- Plugins are available in the Jetpack sidebar that appears on the right side of the block editor. Those live in the `plugins` directory.
+
+When adding a new extension, add a new directory for your extension the matching directory.
 
 ## Extension Structure
 
-Extensions loosely follow this structure:
+Your extension should follow this structure:
 
 ```
 .
-└── block-or-plugin-name/
-	├── block-or-plugin-name.php ← PHP file where the block and its assets are registered.
-	├── editor.js                ← script loaded only in the editor
-	├── editor.scss              ← styles loaded only in the editor
-	├── view.js                  ← script loaded in the editor and theme
-	└── view.scss                ← styles loaded in the editor and theme
+└── blockname/
+	└── blockname.php ← PHP file where the block and its assets are registered.
 ```
 
 If your block depends on another block, place them all in extensions folder:
 
 ```
 .
-├── block-name/
+├── blockname/
 └── sub-blockname/
 ```
 
+**Note that this directory is still being populated. For now, you can find the blocks [here](https://github.com/Automattic/wp-calypso/tree/master/client/gutenberg/extensions).
+
 ## Develop new blocks
 
-Coming when [#11640](https://github.com/Automattic/jetpack/pull/11640) lands.
+You can follow [the instructions here](../docs/guides/gutenberg-blocks.md) to add your own block to Jetpack.
+
+## Block naming conventions
 
+Blocks should use the `jetpack/` prefix, e.g. `jetpack/markdown`.

-
-## getJetpackData()
-
-Gets a list of available blocks, and jetpack's connection status.
-On a Jetpack site, there are special cases when a block is considered unavailable.
-For example, the site may not have the required module, they may not have the required plan,
-or the site admin may have filtered out the use of a certain block.
-
-## registerJetpackBlock()
-
-This util will only register a block if it meets the availability requirements described above.
-
-
-## registerJetpackPlugin()
-
-This util will only register a Gutenberg plugin if it meets the availability requirements described above.

- *   /([\d|-]+)/g,

- *
- * @param {string} text - The text that you want to replace
- * @param {regexp|str} match Must contain a matching group
- * @param {function} fn function that helps replace the matched text
