+# Google Cloud Functions HTTP sample
+
+This recipe shows you how to respond to HTTP requests with a Cloud Function.
+
+View the [source code][code].
+
+[code]: index.js
+
+## Deploy and Test
+
+1. Follow the [Cloud Functions quickstart guide][quickstart] to setup Cloud
+Functions for your project.
+
+1. Clone this repository:
+
+  git clone https://github.com/GoogleCloudPlatform/nodejs-docs-samples.git
+  cd nodejs-docs-samples/functions/http
+
+1. Create a Cloud Storage Bucket to stage our deployment:
+
+  gsutil mb gs://[YOUR_BUCKET_NAME]
+
+ * Replace `[YOUR_BUCKET_NAME]` with the name of your Cloud Storage Bucket.
+
+1. Deploy the "helloGET" function with an HTTP trigger
+
+  gcloud alpha functions deploy publish --bucket [YOUR_BUCKET_NAME] --trigger-http
+
+1. Call the "helloGET" function:
+
+  curl https://[YOUR_PROJECT_REGION].[YOUR_PROJECT_ID].cloudfunctions.net/helloGET
