+## 3.
+
+Now we create a small terraform project that just defines the resources we want to migrate without any configuration:
+
+```
+git checkout step-3
+```
+
+We initialize the terraform project:
+
+```
+terraform init
+```
+
+and we can import the existing resouces into terraform's state. This is done with the command
+```
+terraform import <type>.<resource name> <aws id>
+```
+
+If the resource is defined in a module, it would be
+```
+terraform import module.<module name>.<resource name> <aws id>
+```
+
+The format of the aws ID is always specific to the resource type. For ElasticBeanstalk,
+the application's ID is its name, the environment is an auto-generated ID which can be
+identified via the aws cli for example.
+
+```
+aws elasticbeanstalk describe-environments
+``` 
+
+Identify the environment you want to migrate and note the `EnvironmentId`.
+
+In our example it would be:
+
+```
+terraform import aws_elastic_beanstalk_application.my_ebs coffee-service
+terraform import aws_elastic_beanstalk_environment.my_ebs_staging e-pcpeep3b3z
+```
+
+Terraform now imported the resources into it's state.
