-## Central Connections (v\<MERMAID_RELEASE_VERSION>+)
-
-Mermaid sequence diagrams support **central lifeline connections** using a `()`.
-This is useful to represent messages or signals that connect to a central point, rather than from one actor directly to another.
-
-To indicate a central connection, append `()` to the arrow syntax.
-
-#### Basic Syntax
-
-```mermaid-example
-sequenceDiagram
-    participant Alice
-    participant John
-    Alice->>()John: Hello John
-    Alice()->>John: How are you?
-    John()->>()Alice: Great!
-```
-
-```mermaid
-sequenceDiagram
-    participant Alice
-    participant John
-    Alice->>()John: Hello John
-    Alice()->>John: How are you?
-    John()->>()Alice: Great!
-```
-
 ## Activations
 
 It is possible to activate and deactivate an actor. (de)activation can be dedicated declarations:

-The following half-arrow types are supported for more expressive sequence diagrams. Both solid and dotted variants are available by increasing the number of dashes (`-` → `--`).

-## Central Connections (v<MERMAID_RELEASE_VERSION>+)
-
-Mermaid sequence diagrams support **central lifeline connections** using a `()`.
-This is useful to represent messages or signals that connect to a central point, rather than from one actor directly to another.
-
-To indicate a central connection, append `()` to the arrow syntax.
-
-#### Basic Syntax
-
-```mermaid-example
-sequenceDiagram
-    participant Alice
-    participant John
-    Alice->>()John: Hello John
-    Alice()->>John: How are you?
-    John()->>()Alice: Great!
-```

 ## Activations
 
 It is possible to activate and deactivate an actor. (de)activation can be dedicated declarations:
