+**Apply block locking to patterns or templates**
 
 When building patterns or templates, theme authors can use these same UI tools to set the default locked state of blocks. For example, a theme author could lock various pieces of a header. Keep in mind that by default, users with editing access can unlock these blocks. [Here’s an example of a pattern](https://gist.github.com/annezazu/acee30f8b6e8995e1b1a52796e6ef805) with various blocks locked in different ways and here’s more context on [creating a template with locked blocks](https://make.wordpress.org/core/2022/02/09/core-editor-improvement-curated-experiences-with-locking-apis-theme-json/). You can build these patterns in the editor itself, including adding locking options, before following the [documentation to register them](https://developer.wordpress.org/block-editor/reference-guides/block-api/block-patterns/).
 
+**Apply content locking in patterns or templates**
+
+This functionality was introduced in WordPress 6.1. In contrast to block locking, which removes the ability to remove or move blocks, content locking is both designed for use at the pattern or template level and hides all design tools, while still allowing for the ability to edit the content of the blocks. This provides a great way to simplify the interface for users and preserve a design. When this option is added, the following changes occur:  
+
+- Non-content child blocks (containers, spacers, columns, etc) are hidden from list view, un-clickable on the canvas, and entirely un-editable.
+- The Inspector will display a list of all child 'content' blocks. Clicking a block in this list reveals its settings panel. 
+- The main List View only shows content blocks, all at the same level regardless of actual nesting.
+- Children are move / remove locked automatically.
+- Additional child blocks cannot be inserted, further preserving the design and layout.
+- There is a link in the block toolbar to ‘Modify’ that can be toggled on/off to have access to the broader design tools. 
+
+To adopt this functionality, you need to use `"templateLock":"contentOnly"`. [Here's an example of a pattern](https://gist.github.com/annezazu/d62acd2514cea558be6cea97fe28ff3c) with this functionality in place. For more information, please [review the relevant documentation](https://developer.wordpress.org/block-editor/reference-guides/block-api/block-templates/#locking). 
+
+Note: There is no UI in place to manage content locking and it must be managed at the code level.

 **Change permissions to control locking ability**
 
 Agencies and plugin authors can offer an even more curated experience by limiting which users have [permission to lock and unlock blocks](https://make.wordpress.org/core/2022/05/05/block-locking-settings-in-wordpress-6-0/). By default, anyone who is an administrator will have access to lock and unlock blocks.
