 Posts in the editor move through a couple of different stages between being stored in `post_content` and appearing in the editor. Since the blocks themselves are data structures that live in memory it takes a parsing and serialization step to transform out from and into the stored format in the database.
 
 Customizing the parser is an advanced topic that you can learn more about in the [Extending the Parser](/docs/reference-guides/filters/parser-filters.md) section.

+Patterns are collections of pre-arranged blocks that can be combined and arranged in many ways making it easier to create beautiful content. They act as a head-start, leaving you to plug and play with your content as you see fit and be as simple as single blocks or as complex as a full-page layout.

+# How to create a Block Pattern
+
+## Overview
+
+Patterns are collections of pre-arranged blocks that can be combined and arranged in many ways, making it easier to create beautiful content. They act as a head-start, leaving you to plug and play with your content as you see fit and be as simple as single blocks or as complex as a full-page layout.
+
+## Before you start
+
+To complete this tutorial, you will need the following:
+
+-   WordPress development environment
+-   Familiarity with Plugins and Gutenberg
+
+## Step-by-step guide
+
+### Step 1: Create a sample plugin
+
+Create a directory named `my-block-pattern` and place it under the plugins folder. Create a file called `my-block-pattern.php` inside the folder you just created and paste the following code:
+
+```php
+<?php
+/*
+Plugin Name: Quote Pattern Example Plugin
+*/
+
+register_block_pattern(
+	'my-block-pattern/my-block-pattern',
+	array(
+		'title'       => __( 'Quote with Avatar', 'my-block-pattern' ),
+		'categories'  => array( 'text' ),
+		'description' => _x( 'A big quote with an avatar".', 'Block pattern description', 'my-block-pattern' ),
+		'content'     => '<!-- wp:group --><div class="wp-block-group"><div class="wp-block-group__inner-container"><!-- wp:separator {"className":"is-style-default"} --><hr class="wp-block-separator is-style-default"/><!-- /wp:separator --><!-- wp:image {"align":"center","id":553,"width":150,"height":150,"sizeSlug":"large","linkDestination":"none","className":"is-style-rounded"} --><div class="wp-block-image is-style-rounded"><figure class="aligncenter size-large is-resized"><img src="https://blockpatterndesigns.mystagingwebsite.com/wp-content/uploads/2021/02/StockSnap_HQR8BJFZID-1.jpg" alt="" class="wp-image-553" width="150" height="150"/></figure></div><!-- /wp:image --><!-- wp:quote {"align":"center","className":"is-style-large"} --><blockquote class="wp-block-quote has-text-align-center is-style-large"><p>"Contributing makes me feel like I\'m being useful to the planet."</p><cite>— Anna Wong, <em>Volunteer</em></cite></blockquote><!-- /wp:quote --><!-- wp:separator {"className":"is-style-default"} --><hr class="wp-block-separator is-style-default"/><!-- /wp:separator --></div></div><!-- /wp:group -->',
+	)
+);
+
+?>
+```
+
+### Step 2: Activate the plugin
+
+Go to the plugins section in the WordPress admin and activate `Quote Pattern Example Plugin`
+
+### Step 3: Use the block pattern
+
+Open a new post and click on the Patterns tab. Select the `text` category. Your pattern should be displayed and ready to be used.
+
+## Troubleshooting
+
+-   If the pattern does not appear in the panel, make sure that the plugin is activated and that you're browsing the correct category.
+
+## Conclusion
+
+Creating a block pattern is an efficient way to organize blocks. In this tutorial you have created a pattern that can be reused in any post.
