 ## ID Sets
 
-Inspired by Idiomorph, Morphlex uses ID Sets to match nodes with deeply nested identified elements.
+Inspired by Idiomorph, Morphlex uses ID Sets to match nodes with deeply nested identified elements. Each element is tagged with the set of IDs it contains, allowing for more optimal matching.
+
+Failing an ID Set match, Morphlex will search for the next best match by tag name. If no element can be found, the reference element will be deeply cloned.
 
 ## Node sensitivity
 
-Morphlex will give priority to sensitive elements such as iframes, media players, and form inputs, forcing less sensitive elements to move around them. This works in any direction even if the sensitive element is deeply nested.
+Simply moving certain elements in the DOM tree can cause issues. To account for this, Morphlex gives priority to sensitive elements, moving less sensitive elements around them whenever possible.

 The `currentNode` will be morphed into the state of the `referenceNode`. The `referenceNode` will not be mutated in this process.
