### Customising code samples
The built-in API documentation includes automatically generated code samples for
each of the available API client libraries.
You may customise these samples by subclassing `DocumentationRenderer`, setting
`languages` to the list of languages you wish to support:
from rest_framework.renderers import DocumentationRenderer
class CustomRenderer(DocumentationRenderer):
languages = ['ruby', 'go']
For each language you need to provide an `intro` template, detailing installation instructions and such,
plus a generic template for making API requests, that can be filled with individual request details.
See the [templates for the bundled languages][client-library-templates] for examples.
