## Icons
By default, architecture diagram supports the following icons: `cloud`, `database`, `disk`, `internet`, `server`.
Users can use any of the 200,000+ icons available in iconify.design, or [add custom icons](../config/icons.md).
Users can use any of the 200,000+ icons available in iconify.design, or add other custom icons, by [registering an icon pack](../config/icons.md).
After the icons are installed, they can be used in the architecture diagram by using the format "name:icon-name", where name is the value used when registering the icon pack.

There are ten types of arrows currently supported:
Lines can be solid or dotted, and can end with various types of arrowheads, crosses, or open arrows.

**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!
```
```mermaid

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