+## Special Thanks
+![localstack](./doc/img/localstack-readme-banner.svg)
+[LocalStack](https://www.localstack.cloud/) is a service that mocks AWS, covering a wide range of AWS services. It is not easy to set up an AWS infrastructure for personal development, but LocalStack has lowered the barrier for server application development.
+
+It has been incredibly helpful for my technical learning, and among the open-source software (OSS) I encountered in 2023, LocalStack is undoubtedly the best tool. I would like to take this opportunity to express my gratitude.

+## Development Eviorment Setup
+### Install Prerequisites
+- [Install Golang](https://go.dev/doc/install)
+- [Install make](https://www.gnu.org/software/make/)
+- [Install Docker](https://docs.docker.com/get-docker/)
+- [Install Docker Compose](https://docs.docker.com/compose/install/)
+- Install development tools by running the following command:
+    ```shell
+    make tools
+    ```
+
+### Makefile Usage
+If you want to print help information, you can run the following command:
+```shell
+$ make
+build           Build binary
+changelog       Generate changelog
+clean           Clean project
+docker          Start docker (localstack)
+generate        Generate code from templates
+test            Start unit test
+tools           Install dependency tools 
+```
+
+### localstack Setup
+The localstack is used to simulate the AWS environment. First, you configure a custom profile to use with LocalStack. Add the following profile to your AWS configuration file (by default, this file is at ~/.aws/config):
+
+```shell
+[profile localstack]
+region=us-east-1
+output=json
+endpoint_url = http://localhost:4566
+```
+
+Add the following profile to your AWS credentials file (by default, this file is at ~/.aws/credentials):
+```shell
+[localstack]
+aws_access_key_id=test
+aws_secret_access_key=test
+```
+
+> [!NOTE]  
+> Alternatively, you can also set the AWS_PROFILE=localstack environment variable, in which case the --profile localstack parameter can be omitted in the commands above.
+
+### Run localstack
+```shell
+make docker
+```
