+## Tiny Mermaid
+
+We offer a smaller version of Mermaid that's approximately half the size of the full library. This tiny version doesn't support Mindmap Diagrams, Architecture Diagrams, KaTeX rendering, or lazy loading.
+
+If you need a more lightweight version without these features, you can use [Mermaid Tiny](https://github.com/mermaid-js/mermaid/tree/develop/packages/tiny).
+
 ## Enabling Click Event and Tags in Nodes
 
 A `securityLevel` configuration has to first be cleared. `securityLevel` sets the level of trust for the parsed diagrams and limits click functionality. This was introduced in version 8.2 as a security improvement, aimed at preventing malicious use.

+Each of these techniques are functionally equivalent, but better for different deployments.

 ### [The initialize() call](./getting-started.md#_3-calling-the-javascript-api)
 
 Used when Mermaid is called via an API, or through a `<script>` tag.
 
+### Frontmatter for diagram code
+
+Frontmatter is the term for adding YAML metadata at the start of code. This allows for reconfiguration of a diagram before it is rendered. You can pass metadata Frontmatter with your definition by adding `---` to the lines before and after the definition. This 'triple dash' MUST be the only character on the first line.
+
+Frontmatter uses YAML syntax. It requires any indentation to be consistent and settings are case sensitive. Mermaid will silently ignore misspelling, but badly formed parameters will break the diagram.

 ### [Directives](../config/directives.md)
 
 Allows for the limited reconfiguration of a diagram just before it is rendered. It can alter the font style, color and other aesthetic aspects of the diagram. You can pass a directive alongside your definition inside `%%{ }%%`. It can be done either above or below your diagram definition.

+### Class Styling
+
+Mermaid enables applying styling to classes, which could make styling easier if you want to apply a certain set of styles to multiple elements, as you could just link those elements to a class.
+
+#### Example - Styling a Single Class
+
+```mermaid-example
+block-beta
+  A space B
+  A-->B
+  classDef blue fill:#6e6ce6,stroke:#333,stroke-width:4px;
+  class A blue
+  style B fill:#bbf,stroke:#f66,stroke-width:2px,color:#fff,stroke-dasharray: 5 5
+```
+
+```mermaid
+block-beta
+  A space B
+  A-->B
+  classDef blue fill:#6e6ce6,stroke:#333,stroke-width:4px;
+  class A blue
+  style B fill:#bbf,stroke:#f66,stroke-width:2px,color:#fff,stroke-dasharray: 5 5
+```
+
 In this example, a class named 'blue' is defined and applied to block 'A', while block 'B' receives individual styling. This demonstrates the flexibility of Mermaid in applying both shared and unique styles within the same diagram.
 
 The ability to style blocks individually or through classes provides a powerful tool for enhancing the visual impact and clarity of block diagrams. Whether emphasizing certain elements or maintaining a cohesive design across the diagram, these styling capabilities are central to effective diagramming. The next sections will present practical examples and use cases, followed by tips for troubleshooting common issues.

-Ensure that links between blocks are correctly specified with arrows (--> or ---) to define the direction and type of connection. Also remember that one of the fundaments for block diagram is to give the author full control of where the boxes are positioned so in the example you need to add a space between the boxes:

 ### Identification
 
-Relationships may be classified as either _identifying_ or _non-identifying_ and these are rendered with either solid or dashed lines respectively. This is relevant when one of the entities in question can not have independent existence without the other. For example a firm that insures people to drive cars might need to store data on `NAMED-DRIVER`s. In modelling this we might start out by observing that a `CAR` can be driven by many `PERSON` instances, and a `PERSON` can drive many `CAR`s - both entities can exist without the other, so this is a non-identifying relationship that we might specify in Mermaid as: `PERSON }|..|{ CAR : "driver"`. Note the two dots in the middle of the relationship that will result in a dashed line being drawn between the two entities. But when this many-to-many relationship is resolved into two one-to-many relationships, we observe that a `NAMED-DRIVER` cannot exist without both a `PERSON` and a `CAR` - the relationships become identifying and would be specified using hyphens, which translate to a solid line:

+### Register FontAwesome icon packs (v11.7.0+)
+
+You can register your own FontAwesome icon pack following the ["Registering icon packs" instructions](../config/icons.md).
+
+Supported prefixes: `fa`, `fab`, `fas`, `far`, `fal`, `fad`.

 Mermaid supports Font Awesome if the CSS is included on the website.
 Mermaid does not have any restriction on the version of Font Awesome that can be used.

+### Vertical Markers
+
+The `vert` keyword lets you add vertical lines to your Gantt chart, making it easy to highlight important dates like deadlines, events, or checkpoints. These markers extend across the entire chart and are positioned based on the date you provide. Unlike milestones, vertical markers don’t take up a row. They’re purely visual reference points that help break up the timeline and make important moments easier to spot.

 ## Setting dates
 
 `dateFormat` defines the format of the date **input** of your gantt elements. How these dates are represented in the rendered chart **output** are defined by `axisFormat`.
