+# Node structure
+
+We use a Prosemirror document structure where every element is a `block` with 1 `content` element and one optional group of children (`blockgroup`).
+
+- A `block` can only appear in a `blockgroup` (which is also the type of the root node)
+- Every `block` element can have attributes (e.g.: is it a heading or a list item)
+- Every `block` element can contain a `blockgroup` as second child. In this case the `blockgroup` is considered nested (indented in the UX)
+
+This architecture is different from the "default" Prosemirror / Tiptap implementation which would use more semantic HTML node types (`p`, `li`, etc.). We have designed this block structure instead to more easily:
+
+- support indentation of any node (without complex wrapping logic)
+- supporting animations (nodes stay the same type, only attrs are changed)
+
+## Example
+
+```xml
+<blockgroup>
+    <block>
+        <content>Parent element 1</content>
+        <blockgroup>
+            <block>
+                <content>Nested / child / indented item</content>
+            </block>
+        </blockgroup>
+    </block>
+    <block>
+        <content>Parent element 2</content>
+        <blockgroup>
+            <block>...</block>
+            <block>...</block>
+        </blockgroup>
+    </block>
+    <block>
+        <content>Element 3 without children</content>
+    </block>
+</blockgroup>
+```
