-## Bringing your own models
-
-Sometimes you don't want a model generated.  In this case, you can simply specify an import mapping to tell
-the codegen what _not_ to create.  When doing this, every location that references a specific model will
-refer back to your classes.  Note, this may not apply to all languages...
-
-To specify an import mapping, use the `--import-mappings` argument and specify the model-to-import logic as such:
-
-```
---import-mappings Pet=my.models.MyPet
-```
-
-Or for multiple mappings:
-
-```
---import-mappings Pet=my.models.MyPet,Order=my.models.MyOrder
-```
-or
-```
---import-mappings Pet=my.models.MyPet --import-mappings Order=my.models.MyOrder
-```
-
-## Schema Mapping
-
-One can map the schema to someting else (e.g. external objects/models outside of the package) using the `schemaMappings` option, e.g. in CLI
-```sh
-java -jar target/openapi-generator-cli.jar generate -g java -i src/test/resources/3_0/type-alias.yaml -o /tmp/java2/ --schema-mapping TypeAlias=foo.bar.TypeAlias
-```
-Another example (in conjunction with --type-mappings):
-```sh
-java -jar target/openapi-generator-cli.jar generate -g java -i /tmp/alias.yaml -o /tmp/alias/ --schema-mappings stream=org.springframework.web.servlet.mvc.method.annotation.StreamingResponseBody --type-mappings string+binary=stream
-```
-while /tmp/alias.yaml is as follows:
-```yaml
-openapi: 3.0.3
-info:
-  title: Demo app
-  version: 1.0.0
-servers:
-  - url: /api/v1
-paths:
-  /demo:
-    get:
-      summary: Demo
-      operationId: demo
-      responses:
-        '200':
-          description: Demo response
-          content:
-            text/csv:
-              schema:
-                type: string
-                format: binary
-```
-
 ## Inline Schema Naming
 
-Inline schemas are created as separate schemas automatically and the auto-generated schema name may not look good to everyone. One can customize the name using the `title` field or the `inlineSchemaNameMapping` option, e.g. in CLI
-
-```
-java -jar target/openapi-generator-cli.jar generate -g java -i  src/test/resources/3_0/inline_model_resolver.yaml -o /tmp/java3/ --skip-validate-spec --inline-schema-name-mappings inline_object_2=SomethingMapped,inline_object_4=nothing_new
-```
-
-Another useful option is `inlineSchemaNameDefaults`, which allows you to customize the suffix of the auto-generated inline schema name, e.g. in CLI
-```
---inline-schema-name-defaults arrayItemSuffix=_array_item
-```
-
-Note: Only arrayItemSuffix, mapItemSuffix are supported at the moment.
