 1. Create a Cloud Storage Bucket:
 
-        gsutil mb gs://YOUR_BUCKET_NAME
+        gsutil mb gs://YOUR_INPUT_BUCKET_NAME
 
     This storage bucket is used to upload images for the function to check.
 
+1. Create a second Cloud Storage Bucket:
+
+         gsutil mb gs://YOUR_OUTPUT_BUCKET_NAME
+
+     This second storage bucket is used to store blurred images. (Un-blurred images will not be saved to this bucket.)
+
+     This is necessary because saving the blurred image to the input bucket would cause your function to be invoked a second time with the blurred image itself.
+
 1. Deploy the `blur_offensive_images` function with a Storage trigger:
 
-        gcloud functions deploy blur_offensive_images --trigger-bucket=YOUR_BUCKET_NAME --runtime python37
+        gcloud functions deploy blur_offensive_images --trigger-bucket=YOUR_INPUT_BUCKET_NAME --set-env-vars BLURRED_BUCKET_NAME=YOUR_OUTPUT_BUCKET_NAME --runtime python37
 
-    * Replace `YOUR_BUCKET_NAME` with the name of the Cloud Storage Bucket you created earlier.
+    * Replace `YOUR_INPUT_BUCKET_NAME` and `YOUR_OUTPUT_BUCKET_NAME` with the names of the respective Cloud Storage Buckets you created earlier.
 
 1.  Upload an offensive image to the Storage bucket, such as this image of
     a flesh-eating zombie: https://cdn.pixabay.com/photo/2015/09/21/14/24/zombie-949916_1280.jpg
