+### Requirements for Merging a Pull Request
+
+The requirements to accept a pull request are as follows:
+
+- Features not provided by the OpenAI API will not be accepted.
+- The functionality of the feature must match that of the official OpenAI API.
+- All pull requests should be written in Go according to common conventions, formatted with `goimports`, and free of warnings from tools like `golangci-lint`.
+- Include tests and ensure all tests pass.
+- Maintain test coverage without any reduction.
+- All pull requests require approval from at least one Go OpenAI maintainer.
+
+**Note:** 
+The merging method for pull requests in this repository is squash merge.
+
+### Creating a Pull Request
+- Fork the repository.
+- Create a new branch and commit your changes.
+- Push that branch to GitHub.
+- Start a new Pull Request on GitHub. (Please use the pull request template to provide detailed information.)
+
+**Note:** 
+If your changes introduce breaking changes, please prefix your pull request title with "[BREAKING_CHANGES]".
+
+### Code Style
+In this project, we adhere to the standard coding style of Go. Your code should maintain consistency with the rest of the codebase. To achieve this, please format your code using tools like `goimports` and resolve any syntax or style issues with `golangci-lint`.
+
+**Run goimports:**
+```
+go install golang.org/x/tools/cmd/goimports@latest
+```
+
+```
+goimports -w .
+```
+
+**Run golangci-lint:**
+```
+go install github.com/golangci/golangci-lint/cmd/golangci-lint@latest
+```
+
+```
+golangci-lint run --out-format=github-actions
+```
+
+### Unit Test
+Please create or update tests relevant to your changes. Ensure all tests run successfully to verify that your modifications do not adversely affect other functionalities.
+
+**Run test:**
+```
+go test -v ./...
+```
+
+### Integration Test
+Integration tests are requested against the production version of the OpenAI API. These tests will verify that the library is properly coded against the actual behavior of the API, and will fail upon any incompatible change in the API.
+
+**Notes:**
+These tests send real network traffic to the OpenAI API and may reach rate limits. Temporary network problems may also cause the test to fail.
+
+**Run integration test:**
+```
+OPENAI_TOKEN=XXX go test -v -tags=integration ./api_integration_test.go
+```
+
+If the `OPENAI_TOKEN` environment variable is not available, integration tests will be skipped.
+

+
+We wholeheartedly welcome your active participation. Let's build an amazing project together!
