+
+This page lists the available layout algorithms supported in Mermaid diagrams.
+
+## 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
+  D
+```
+
+```mermaid
+---
+config:
+  layout: tidy-tree
+---
+mindmap
+root((mindmap is a long thing))
+  A
+  B
+  C
+  D
+```
+
+```mermaid-example
+---
+config:
+  layout: tidy-tree
+---
+mindmap
+root((mindmap))
+    Origins
+      Long history

+            Creative techniques
+            Strategic planning
+            Argument mapping
+```

+
+## Note
+
+- Currently, tidy-tree is primarily supported for mindmap diagrams.
