+In this example, we have made 2 modules, User Module and Customer Module.I have just put dummy resources like s3 , kinesis for example. Module can have any number of resources.Companies can have their own registry for modules which will be used by other teams.
+
+Steps for creating resources in dev environment.
+
+```
+cd module-example/env/dev
+terraform init
+terraform plan -out=myplan
+terraform apply
+```
+
+Similar approach will be taken for stage/prod environment.We can pass it different values for different environment.
+
+If you will see, I have changed the provider region for each environment.
