+There are two examples in here:
+ - TodoEmbeddable
+ - TodoRefEmbeddable
+
+ # TodoEmbeddable
+
+ The first example you should review is the HelloWorldEmbeddable.  That is as basic an embeddable as you can get.
+ This embeddable is the next step up - an embeddable that renders dynamic input data. The data is simple: 
+  - a required task string
+  - an optional title
+  - an optional icon string
+  - an optional search string
+
+It also has output data, which is `hasMatch` - whether or not the search string has matched any input data.
+
+`hasMatch` is a better fit for output data than input data, because it's state that is _derived_ from input data.
+
+For example, if it was input data, you could create a TodoEmbeddable with input like this:
+
+```ts
+ todoEmbeddableFactory.create({ task: 'take out the garabage', search: 'garbage', hasMatch: false });
+```
+
+That's wrong because there is actually a match from the search string inside the task.
+
+The TodoEmbeddable component itself doesn't do anything with the `hasMatch` variable other than set it, but
+if you check out `SearchableListContainer`, you can see an example where this output data is being used.
+
+## TodoRefEmbeddable
+
+This is an example of an embeddable based off of a saved object. The input is just the `savedObjectId` and
+the `search` string. It has even more output parameters, and this time, it does read it's own output parameters in
+order to calculate `hasMatch`.
+
+Output:
+```ts
+{ 
+  hasMatch: boolean,
+  savedAttributes?: TodoSavedAttributes
+}
+```
+
+`savedAttributes` is optional because it's possible a TodoSavedObject could not be found with the given savedObjectId.
