springdoc-openapi-ui swagger 3 change API description

I am new to String and Swagger 3. How can I change the default API description i.e. OpenAPI definition in Swagger springdoc-openapi-ui swagger 3

Also version, developer information..

I am using

implementation "org.springframework.boot:spring-boot-starter-web:2.6.6"
implementation "org.springdoc:springdoc-openapi-ui:1.6.8"

In search, I see only they are showing default Swagger UI

Simply use following annotations :

In application launcher class(Configuration class):

@OpenAPIDefinition(info=@Info(title="Name of project"))

In Controller imports should be as follows :

import io.swagger.v3.oas.annotations.*

Class level:

@OpenAPIDefinition()

OR

@Tag(name = "", description = "")
public class ApiController {

Method level :

@PutMapping(value = "/test")
@Operation(summary = "info...")
@ApiResponses(value = {
        @ApiResponse(responseCode = "200", description = "successfully updated"),
        @ApiResponse(responseCode = "400", description = "Bad request"),
        @ApiResponse(responseCode = "500", description = "Internal Server Error")})

And config class should be like this :

@Configuration
public class ApiDocumentationConfig {

    @Bean
    public OpenAPI apiDocConfig() {
        return new OpenAPI()
                .info(new Info()
                        .title("example API")
                        .description("example API for routing ")
                        .version("0.0.1")
                        .contact(new Contact()
                                .name("example")
                                .email("exaample@z.com")))
                .externalDocs(new ExternalDocumentation()
                        .description("Documentation")
                        .url("https:/wiki...."));
    }

    @Bean
    public MvcConfig mvcConfig() {
        return new MvcConfig();
    }
}
