 ## Merge arrays of objects together, matching on a key
-There are several parts of the complex expression. 
-The first part is doing the hard work, it creates a map from the arrays keyed by '.a', so that there are no duplicates. 
-Then there's another reduce that converts that map back to an array.
+The approach, at a high level, is to reduce into a merged map (keyed by the unique key)
+and then convert that back into an array.
+
+First the expression will create a map from the arrays keyed by '.a', the unique field we want to merge by.
+The reduce operator is merging '({}; . * $item )', so array elements with the matching key will be merged together.
+
+Next, we convert the map back to an array, using reduce again, concatenating all the map values together.
+
 Finally, we set the result of the merged array back into the first doc.

-To use this, you will need to update '.myArray' to be the expression to your array (e.g. .my.array), and '.a' to be the key field of your array (e.g. '.name')
