 title: Customization

-## User-defined Templates
-
-The most common scenario for user customization is to override the built-in templates with small modifications. That scenario's documentation is in our [templating](./templating.md) page, and differs from user-defined templates.
-
-Prior to release 5.0.0, whenever a user wanted to include templates which weren't built-in or weren't known to the generator at compile time, they'd need to follow the more involved approach of creating a custom generator as documented later in this document. Beginning in 5.0.0, a user may now provide additional supporting files and extensions to built-in templates via configuration. This feature requires using the external configuration file feature.
-
-Consider that you might want to add some static documentation such as `AUTHORS.md` and a custom tooling script. Rather than a single file for API definitions you also want an implementation file and a separate interface file for each.
-
-You might have an external configuration file named `config.yaml` which defines additional properties like this for a `kotlin` client generator:
-
-```yaml
-additionalProperties:
-  artifactId: kotlin-petstore-client
-  serializableModel: "true"
-  dateLibrary: java8
-```
-
-You would generate via CLI with the command:
-
-```shell script
-openapi-generator generate -g kotlin -i spec.yaml -o outdir -c config.yaml
-```
-
-To support the above scenario with custom templates, ensure that you're pointing to your custom template directory and add a `files` node with template file definitions to your config:
-
-```
-templateDir: my_custom_templates
-additionalProperties:
-  artifactId: kotlin-petstore-client
-  serializableModel: "true"
-  dateLibrary: java8
-files:
-  AUTHORS.md: {}
-  api_interfaces.mustache:
-    templateType: API
-    destinationFilename: Interface.kt
-  api.mustache:
-    templateType: API
-    destinationFilename: Impl.kt
-  other/check.mustache:
-    folder: scripts
-    destinationFilename: check.sh
-    templateType: SupportingFiles
-```
-
-The keys under the `files` node are your template filenames. These honor the same resolution order as all other templates.
-
-The above configuration will do the following:
-
-* Copy `my_custom_templates/AUTHORS.md` to the generated output directory without processing via the template engine (due to template file extension). The empty object definition following `AUTHORS.md` allows the tool to infer the target output filename in the root of the output directory.
-* Compile a user-provided `my_custom_templates/api_interfaces.mustache` following our usual API template compilation logic. That is, one file will be created per API; APIs are generated defined according to tags in your spec documentation. The destination filename of `Interface.kt` will act as a suffix for the filename. So, a tag of `Equipment` will output a corresponding `EquipmentInterface.kt`.
-* Because `api.mustache` is the same mustache filename as used in your target generator (`kotlin` in this example), we support the following:
-  - The destination filename provides a suffix for the generated output. APIs generate per tag in your specification. So, a tag of `Equipment` will output a corresponding `EquipmentImpl.kt`. This option will be used whether `api.mustache` targets a user customized template or a built-in template.
-  - The built-in template will be used if you haven't provided an customized template. The kotlin generator defines the suffix as simply `.kt`, so this scenario would modify only the generated file suffixes according to the previous bullet point.
-  - Your `api.mustache` will be used if it exists in your custom template directory. For generators with library options, such as `jvm-okhttp3` in the kotlin generator, your file must exist in the same relative location as the embedded template. For kotlin using the `jvm-okhttp3` library option, this file would need to be located at `my_custom_templates/libraries/jvm-okhttp/api.mustache`. See [templating](./templating.md) for more details.
-* Compile `my_custom_templates/other/check.mustache` with the supporting files bundle, and output to `scripts/check.sh` in your output directory. Note that we don't currently support setting file flags on output, so scripts such as these will either have to be sourced rather than executed, or have file flags set separately after generation (external to our tooling).
-
-The `templateType` option will default to `SupportingFiles`, so the option for `other/check.mustache` is redundant and provided to demonstrate the full template file configuration options. The available template types are:
-
-* API
-* APIDocs
-* APITests
-* Model
-* ModelDocs
-* ModelTests
-* SupportingFiles
-
-Excluding `SupportingFiles`, each of the above options may result in multiple files. API related types create a file per API. Model related types create a file for each model.
-
-Note that user-defined templates will merge with built-in template definitions. If a supporting file with the sample template file path exists, it will be replaced with the user-defined template, otherwise the user-defined template will be added to the list of template files to compile. If the generator's built-in template is `model_docs.mustache` and you define `model-docs.mustache`, this will result in duplicated model docs (if `destinationFilename` differs) or undefined behavior as whichever template compiles last will overwrite the previous model docs (if `destinationFilename` matches the extension or suffix in the generator's code).

 ## Custom Generator (and Template)
  
 <a id="creating-a-new-template"></a> If none of the built-in generators suit your needs and you need to do more than just modify the mustache templates to tweak generated code, you can create a brand new generator and its associated templates. OpenAPI Generator can help with this, using the `meta` command:

 ### Verify output
 
 Creating a new generator will be an iterative task. Once you've generated the sample, you'll want to try it out. For compiled client/server outputs, this would mean running the code or creating a small sample project to consume your artifact just to make sure it works.
