+## Markdown Strings
+
+The "Markdown Strings" feature enhances flowcharts and mind maps by offering a more versatile string type, which supports text formatting options such as bold and italics, and automatically wraps text within labels.
+
+```mermaid-example
+%%{init: {"flowchart": {"htmlLabels": false}} }%%
+flowchart LR
+subgraph "One"
+  a("`The **cat**
+  in the hat`") -- "edge label" --> b{{"`The **dog** in the hog`"}}
+end
+subgraph "`**Two**`"
+  c("`The **cat**
+  in the hat`") -- "`Bold **edge label**`" --> d("The dog in the hog")
+end
+```
+
+```mermaid
+%%{init: {"flowchart": {"htmlLabels": false}} }%%
+flowchart LR
+subgraph "One"
+  a("`The **cat**
+  in the hat`") -- "edge label" --> b{{"`The **dog** in the hog`"}}
+end
+subgraph "`**Two**`"
+  c("`The **cat**
+  in the hat`") -- "`Bold **edge label**`" --> d("The dog in the hog")
+end
+```
+
+Formatting:
+
+- For bold text, use double asterisks \*\* before and after the text.
+- For italics, use single asterisks \* before and after the text.
+- With traditional strings, you needed to add <br> tags for text to wrap in nodes. However, markdown strings automatically wrap text when it becomes too long and allows you to start a new line by simply using a newline character instead of a <br> tag.
+
+This feature is applicable to node labels, edge labels, and subgraph labels.
+
 ## Interaction
 
 It is possible to bind a click event to a node, the click can lead to either a javascript callback or to a link which will be opened in a new browser tab. **Note**: This functionality is disabled when using `securityLevel='strict'` and enabled when using `securityLevel='loose'`.

 Mindmap uses the experimental lazy loading & async rendering features which could change in the future. From version 9.4.0 this diagram is included in mermaid but use lazy loading in order to keep the size of mermaid down. This is important in order to be able to add additional diagrams going forward.

 In case you have more than 12 sections, the color scheme will start to repeat.
