+# Diagrams
+
+Diagrams help to communicate complex relationships and interconnections between
+different technical components, and are a great addition to project
+documentation. Material for MkDocs integrates with [Mermaid.js][1], a very
+popular and flexible solution for drawing diagrams.
+
+  [1]: https://mermaid-js.github.io/mermaid/
+
+## Configuration
+
+### SuperFences
+
+[:octicons-file-code-24: Source][2] ·
+:octicons-beaker-24: Experimental ·
+[:octicons-heart-fill-24:{: .tx-heart } Insiders only][2]{: .tx-insiders }
+
+The [SuperFences][3] extension, which is part of [Python Markdown
+Extensions][4], allows for adding __custom fences__, which can be used to
+render [Mermaid.js][1] diagrams with zero effort:
+
+``` yaml
+markdown_extensions:
+  - pymdownx.superfences
+      custom_fences:
+        - name: mermaid
+          class: mermaid-experimental
+          format: !!pymdownx.superfences.fence_code_format
+```
+
+No further configuration is necessary. Material for MkDocs will automatically
+load and initialize the [Mermaid.js][1] runtime when a page includes a [fenced
+`mermaid` block][5]. Furthermore:
+
+- [x] Works with [instant loading][6] without any additional effort
+- [x] Diagrams automatically use fonts and colors defined in `mkdocs.yml`[^1]
+- [x] Fonts and colors can be customized with [additional stylesheets][7]
+- [x] Support for both, light and dark color schemes
+
+_While it's also possible to integrate [Mermaid.js][1] using existing
+third-party solutions[^2], the new native integration is recommended as it
+ensures interoperability with all Material for MkDocs features._
+
+  [^1]:
+    While all [Mermaid.js][1] features should work out-of-the-box, Material for
+    MkDocs will currently only adjust the fonts and colors for flow charts,
+    class and state diagrams. Support for further diagram types will be added
+    gradually.
+
+  [^2]:
+    If you don't want to use the native integration, [mkdocs-mermaid2-plugin][8]
+    might be a good alternative. However, note that this plugin cannot be used
+    in conjunction with the [mkdocs-minify-plugin][9] and doesn't integrate
+    natively.

+
+## Usage
+
+### Using diagrams
+
+Mermaid diagrams are written as [code blocks][10] with the help of the
+[SuperFences][11] extension. They must be enclosed with two separate lines
+containing three backticks:
+
+_Example_:
+
+```` markdown
+``` mermaid
+graph LR
+  A[Start] --> B{Error?};
+  B -->|Yes| C[Hmm...];
+  C --> D[Debug];
+  D --> B;
+  B ---->|No| E[Yay!];
+```
+````
+
+_Result_:
+
+[![Diagram][12]{: style="width: 100%; max-width: 594px" }][12]
+
+_See the [official documentation][1] to learn about all available diagram 
+types._
