-#### Busting Cache
-In certain circumstances, the CircleCI cache can become stale. In order to bust the cache, we've implemented a runtime boolean parameter in Circle CI creatively name BUST_CACHE. To execute:
-1. Navigate to the branch in Circle CI believed to have stale cache.
-1. Click on the 'Trigger Pipeline' button.
-1. Add Parameter -> Parameter Type = boolean , Name = BUST_CACHE ,Value = true
-1. Click 'Trigger Pipeline'

 - Working with multiple pages
 There are instances where multiple browser pages will needed to verify multi-page or multi-tab application behavior. Make sure to use the `@2p` annotation as well as name each page appropriately: i.e. `page1` and `page2` or `tab1` and `tab2` depending on the intended use case. Generally pages should be used unless testing `sharedWorker` code, specifically.
 
+- Working with file downloads and JSON data
+Open MCT has the capability of exporting certain objects in the form of a JSON file handled by the chrome browser. The best example of this type of test can be found in the exportAsJson test.

+```js
+const [download] = await Promise.all([

+  page.getByLabel('Export as JSON').click() // Triggers the download
+]);
+
+// Wait for the download process to complete

+// Read the contents of the downloaded file using readFile from fs/promises
+const fileContents = await fs.readFile(path, 'utf8');
+const jsonData = JSON.parse(fileContents);

+// Use the function to retrieve the key
+const key = getFirstKeyFromOpenMctJson(jsonData);
