+
+## Supported Layouts
+
+- **elk**: [ELK (Eclipse Layout Kernel)](https://www.eclipse.org/elk/)
+- **tidy-tree**: Tidy tree layout for hierarchical diagrams [Tidy Tree Configuration](/config/tidy-tree)
+- **cose-bilkent**: Cose Bilkent layout for force-directed graphs
+- **dagre**: Dagre layout for layered graphs
+
+## How to Use
+
+You can specify the layout in your diagram's YAML config or initialization options. For example:
+
+```mermaid-example
+---
+config:
+  layout: elk
+---
+graph TD;
+  A-->B;
+  B-->C;
+```
+
+```mermaid

+# Tidy-tree Layout
+
+The **tidy-tree** layout arranges nodes in a hierarchical, tree-like structure. It is especially useful for diagrams where parent-child relationships are important, such as mindmaps.
+
+## Features
+
+- Organizes nodes in a tidy, non-overlapping tree
+- Ideal for mindmaps and hierarchical data
+- Automatically adjusts spacing for readability
+
+## Example Usage
+
+```mermaid-example
+---
+config:
+  layout: tidy-tree
+---
+mindmap
+root((mindmap is a long thing))
+  A
+  B
+  C

-The method `Layout.layout` modifies `treeData` inplace. It returns an object like `{ result: treeData, boundingBox: {left: num, right: num, top: num, bottom: num} }`. `result` is the same object `treeData` with calculated coordinates, `boundingBox` are the coordinates for the whole tree:
-
-![](./screenshots/1.png)
-
-The red dashed lines are the bounding boxes for each node. `Layout.layout()` produces coordinates to draw nodes, which are the grey boxes with black border.
-
-The library also provides a class `Tree` and a method `layout`.
-
-```js
-/**
- * Constructor for Tree.
- * @param {number} width - width of bounding box
- * @param {number} height - height of bounding box
- * @param {number} y - veritcal coordinate of bounding box
- * @param {array} children - a list of Tree instances
- */
-new Tree(width, height, y, children);
-
-/**
- * Calculate x, y coordindates and assign them to tree.
- * @param {Object} tree - a Tree object
- */
-layout(tree);
-```
-
-In case your data structure are not the same as provided by the example above, you can refer to `src/helpers.js` to implement a `Layout` class that converts your data to a `Tree`, then call `layout` to calculate the coordinates for drawing.
