-#### Supported Arrow Types
-
-**Standard Arrow Types**
+There are ten types of arrows currently supported:

 | Type     | Description                                          |

 | `--)`    | Dotted line with a open arrow at the end (async)     |

-**Half-Arrows (v\<MERMAID_RELEASE_VERSION>+)**
-
-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 (`-` → `--`).
-

-| `\\--`  | Dotted line with reverse bottom stick half arrowhead |
-
-## 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!

-    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:

-#### Supported Arrow Types
-
-**Standard Arrow Types**
+There are ten types of arrows currently supported:

 | Type     | Description                                          |

 | `--)`    | Dotted line with a open arrow at the end (async)     |

-**Half-Arrows (v<MERMAID_RELEASE_VERSION>+)**
-
-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!
-```

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