+
+It is possible to generate diagrams and flowcharts from text using [Mermaid][mermaid].
+
+In order to generate a diagram or flowchart, you should write your text inside the `mermaid` block.
+
+Example:
+
+    ```mermaid
+    graph TD;
+      A-->B;
+      A-->C;
+      B-->D;
+      C-->D;
+    ```
+
+Becomes:
+
+```mermaid
+graph TD;
+  A-->B;
+  A-->C;
+  B-->D;
+  C-->D;
+```
+
+For details see the [Mermaid official page][mermaid].
