 - `weather-api/` - Lambda Function to be used with API Gateway that returns weather for Tulsa, OK from the OpenWeatherMap API
 - `weather-app/` - Simple Angular SPA that retrieves the weather data from the API and displays a subset of it on a page

 ## Lessons Learned
 
-1. CloudFormatioon Custom Resources are very powerful, but they can also be tricky to test and debug due to how they work.
+1. CloudFormation Custom Resources are very powerful, but they can also be tricky to test and debug due to how they work.
 2. I learned a pretty clean way to do a sleep timer in NodeJS:
    ```
    import { promisify } from "util";
    const sleep = promisify(setTimeout);
    await sleep(1000);
    ```
-3. `cfn-response` and similar libraries are helpful when dealing with CloudFormatioon Custom Resources, but in some cases lack flexibility to modify the responses send to CloudFormatioon.
