 ## Syntax

 The syntax for creating Mindmaps is simple and relies on indentation for setting the levels in the hierarchy.

-In the following example you can see how there are 3 different levels. One with starting at the left of the text and another level with two rows starting at the same column, defining the node A. At the end there is one more level where the text is indented further then the previous lines defining the nodes B and C.
+In the following example you can see how there are 3 different levels of indentation. The leftmost indentation is the root of the mindmap. There can only be one root and if you by misstake add two of them on the same level there will be a syntax error. Rows with larger indentation will be connected as children to the previous row with lower indentation. Based on that you can see in the example how the nodes B and C both are children to node A whci in turn is a child of the node Root.

 ## Syntax

 The syntax for creating Mindmaps is simple and relies on indentation for setting the levels in the hierarchy.

-In the following example you can see how there are 3 different levels. One with starting at the left of the text and another level with two rows starting at the same column, defining the node A. At the end there is one more level where the text is indented further then the previous lines defining the nodes B and C.
+In the following example you can see how there are 3 different levels of indentation. The leftmost indentation is the root of the mindmap. There can only be one root and if you by misstake add two of them on the same level there will be a syntax error. Rows with larger indentation will be connected as children to the previous row with lower indentation. Based on that you can see in the example how the nodes B and C both are children to node A whci in turn is a child of the node Root.

Alois Klink	1a5e7315c0	fix(mermaid): default mermaid back to CommonJS Default mermaid back to being a CommonJS module. Improrting Mermaid as CommonJS (e.g. using `require("mermaid")`) is normally broken (since v8), due to it's dependency on d3, which is now ESM only. However, it looks like some software (e.g. TypeScript, in the docusaurus project) could still handle the CommonJS version of Mermaid. This commit now means that older versions of Node/build-tools should now default to using the CommonJS version of Mermaid. Newer tools should still see that the `"module"` field points to ESM, or use the `exports["."]["import"]` field to load ESM.	2022-11-06 23:41:09 +00:00
