 # 11. Get Patient Data using FHIR
 We now have a valid access token, and can use it to send requests to the FHIR endpoint to retrieve our patient's data. See http://docs.smarthealthit.org/authorization/#4-app-accesses-clinical-data-via-fhir-api

+We will depend on the `fhir-client.js` library to retrieve these resources using a couple of the available APIs:
 
 - `smart.patient.read()`: This returns the context for the patient the app was launched for.
 - `smart.patient.api.fetchAll()`: This will use the fhir.js API to retrieve a complete set of resources for the patient in context.
-- `smart.byCodes()`: 
+- `smart.byCodes()`: A utility function that returns a function to search a given resource for specific codes returned from that response.
 
 Here's the relevant code in `example-smart-app.js`:

 We'll walk through the code first, and then modify it to retrieve the data you require for your specific patient. 
 
-Also, the `fhir-client.js` library defines several more API’s that will come in handy while developing smart app. Check them out here:
