 - A lambda function in charge of the translation from JSON API format to dynamoDB objects and managing the relationships and the optional parameters provided in the request
 - An API Gateway configured to received the REST HTTP requests and proxying the Lambda
 
+It also create three S3 buckets, one for storing the lambda code (nammed lambda-jsonapi-code-bucket) and the two other for receiving the ‘staging’ and ‘production’ version of the application (respectively nammed ember-aws-ehipster-staging and ember-aws-ehipster-production)

 Several Terraform files are available, each one creating the needed component and their relationships with each other.
 
 Installation
 ------------------------------------------------------------------------------
 
-The lambda code needs to be stored in a S3 bucket before running the Terraform scripts.
-The script is available in the cloud/lambda directory of this project.
-The following operations need to be performed (adapting the region you are using):
-
-```
-cp ../lambda/lambda-jsonapi.js .
-zip lambda-jsonapi.zip lambda-jsonapi.js
-aws s3api create-bucket --bucket=lambda-jsonapi-code-bucket --region=us-east-1
-aws s3 cp lambda-jsonapi.zip s3://lambda-jsonapi-code-bucket/v1.0.0/lambda-jsonapi.zip
-```
 One this is done, simply run the terraform script :
 ```
+terraform init
 terraform apply -var bucket_name=<bucket name for static web site>
-```
-For a strange reason I don't understand, the first time you run the terraform command, the mapping for the integration response fails. You have to run the command again to have your complete setup.
