+Replicate AWS in local with localstack
+======================================
+
+An example on how to use localstack to mock AWS services. The following instructions focus on how to run localstack and deploy:
+* a dynamodb table
+* a lambda reading data and putting data to this table
+
+Usage
+-----
+
+Run
+
+```bash
+docker-compose up -d
+docker-compose logs -f localstack
+```
+
+Wait for set up to be done, then create a dynamodb table:
+
+```bash
+aws dynamodb create-table \
+  --endpoint-url http://localhost:4569 \
+  --table-name table_1 \
+  --attribute-definitions AttributeName=id,AttributeType=S \
+  --key-schema AttributeName=id,KeyType=HASH \
+  --provisioned-throughput ReadCapacityUnits=20,WriteCapacityUnits=20
+```
+
+To check if the table was properly created, run:
+
+```bash
+aws dynamodb list-tables --endpoint-url http://localhost:4569
+```
+
+Create and deploy the lambda function:
+
+```bash
+cd lambda
+zip -r ../lambda.zip .
+cd ..
+aws lambda create-function \
+  --function-name counter \
+  --runtime nodejs8.10 \
+  --role fake_role \
+  --handler main.handler \
+  --endpoint-url http://localhost:4574 \
+  --zip-file fileb://$PWD/lambda.zip
+```
+
+Invoke the function multiple times and scan the table to see new items and their counters being incremented:
+
+``bash
+aws lambda invoke --function-name counter --endpoint-url=http://localhost:4574 --payload '{"id": "test"}' output.txt
+aws dynamodb scan --endpoint-url http://localhost:4569 --table-name table_1
+
+aws lambda invoke --function-name counter --endpoint-url=http://localhost:4574 --payload '{"id": "test2"}' output.txt
+aws dynamodb scan --endpoint-url http://localhost:4569 --table-name table_1
+```

+Deploy AWS resources in localstack with Terraform
+=================================================
+
+An example on how to use Terraform to deploy localstack resources that mock AWS services. The following instructions focus on how to deploy:
+* a dynamodb table
+* a lambda reading data and putting data to this table
+
+Usage
+-----
+
+Run
+
+```bash
+docker-compose up -d
+docker-compose logs -f localstack
+```
+
+Create the lambda:
+
+```bash
+cd lambda
+zip -r ../lambda.zip .
+cd ..
+```
+
+Wait for set up to be done, then apply the Terraform configuration:
+
+```bash
+terraform init
+terraform plan
+terraform apply --auto-approve
+```
+
+Invoke the lambda multiple times and scan the table to see new items and their counters being incremented:
+
+``bash
+aws lambda invoke --function-name counter --endpoint-url=http://localhost:4574 --payload '{"id": "test"}' output.txt
+aws dynamodb scan --endpoint-url http://localhost:4569 --table-name table_1
