+# Integrated Swagger API Specification
+
+## Introduction
+We have used `swagger-codegen-maven-plugin` to generate api interfaces from the swagger specification file. This is an automated process, and the generated code is placed in `target/generated-sources/swagger` directory. You can directly use these interfaces in your code.
+
+## Swagger Version
+Swagger version of swagger specification file should be Swagger 2.0
+
+If you are using Swagger 3.0, you can convert it to Swagger 2.0 using the following command:
+
+```bash
+pnpm install -g api-spec-converter
+api-spec-converter          \
+    --from openapi_3        \
+    --to swagger_2          \
+    --syntax yaml           \
+    --order default         \
+    --check                 \
+    --dummy                 \
+    your-swagger-3.0.yaml
+```
