+/* 
+This example shows how to add meta data to shapes when they are created and
+updated. In this case we are adding `updatedBy` and `updatedAt` fields.
+
+[1]
+getInitialMetaForShape is a method you can replace at runtime. Here we use 
+a callback on the onMount prop to replace the default implementation with 
+our own.
+
+[2]
+Here we're using the side effects API to add meta data to shapes when they are
+updated. You can use the side effects API to do something on create, update or
+delete, and you can target many things including: shapes, pages, the camera, 
+the pointer etc.
+
+[3]
+All tldraw shapes have a meta property with a type of unknown. To type your 
+meta data you can use a union like this.
+
+[4]
+A minimal ui component that displays the meta data of the selected shape. We 
+use track to make sure that the component is re-rendered when the signals it's 
+tracking change. Check out the signia docs for more info:
