Quickstart
First follow drf-yasg quickstart,
then extend the configuration in following way.
Extending drg-yasg configuration
Assuming you are using drf-yasg configuration like below (which is drf-yasg default):

SWAGGER_SETTINGS = {
'DEFAULT_AUTO_SCHEMA_CLASS': 'drf_yasg.inspectors.SwaggerAutoSchema',

'DEFAULT_FIELD_INSPECTORS': [
'drf_yasg.inspectors.CamelCaseJSONFilter',
'drf_yasg.inspectors.RecursiveFieldInspector',
'drf_yasg.inspectors.ReferencingSerializerInspector',
'drf_yasg.inspectors.ChoiceFieldInspector',
'drf_yasg.inspectors.FileFieldInspector',
'drf_yasg.inspectors.DictFieldInspector',
'drf_yasg.inspectors.JSONFieldInspector',
'drf_yasg.inspectors.HiddenFieldInspector',
'drf_yasg.inspectors.RelatedFieldInspector',
'drf_yasg.inspectors.SerializerMethodFieldInspector',
'drf_yasg.inspectors.SimpleFieldInspector',
'drf_yasg.inspectors.StringDefaultFieldInspector',
],
'DEFAULT_FILTER_INSPECTORS': [
'drf_yasg.inspectors.CoreAPICompatInspector',
],
'DEFAULT_PAGINATOR_INSPECTORS': [
'drf_yasg.inspectors.DjangoRestResponsePagination',
'drf_yasg.inspectors.CoreAPICompatInspector',
],
}

Apply following changes:
SWAGGER_SETTINGS = {
'DEFAULT_AUTO_SCHEMA_CLASS': 'drf_yasg_json_api.inspectors.SwaggerAutoSchema', # Overridden

'DEFAULT_FIELD_INSPECTORS': [
'drf_yasg_json_api.inspectors.NamesFormatFilter', # Replaces CamelCaseJSONFilter

],
'DEFAULT_FILTER_INSPECTORS': [
'drf_yasg_json_api.inspectors.DjangoFilterInspector', # Added (optional), requires django_filter
'drf_yasg.inspectors.CoreAPICompatInspector',
],
'DEFAULT_PAGINATOR_INSPECTORS': [
'drf_yasg_json_api.inspectors.DjangoRestResponsePagination', # Added
'drf_yasg.inspectors.DjangoRestResponsePagination',
'drf_yasg.inspectors.CoreAPICompatInspector',
],
}

Renderers and parsers
JSON API schema of your view's response or request will be generated if you use django-rest-framework-json-api's
JSONAPIRenderer or JSONAPIParser respectively.
But since you have already used them to render or parse, not just to generate schema (haven't you?),
you probably only need to alter the configuration as described above.
That's it!
Features
Fields and query params extraction follows Django REST framework JSON API.
Main request/response JSON API schema support:

data field with id, type, relationships, attributes structure
Schema based on view's main serializer. It accessed through view's get_serializer method,
the same way drf-yasg does it.
Use GenericAPIView or APIView and define get_serializer manually.
Fields and their source:

id – id field or other serializer field that matches the model pk
field or in-the-fly generated serializer field for model pk
type – serializer's model JSON API resource name or view's resource name,
the same way Django REST framework JSON API does it
relationships – all serializer fields of RelatedField and ManyRelatedField class
attributes – all other serializer fields

included field and include query param
Schema based on serializers defined in included_serializer attribute of view's main serializer where each one is
treated in the same way as view's main serializer (data field).

filter query param
If view uses django_filters.DjangoFilterBackend as filter backend,
schema of filter[] query param will be generated based on view's filterset_fields attribute.

pagination
If view uses JsonApiPageNumberPagination or JsonApiLimitOffsetPagination as pagination_class,
schema of links and meta, consistent with those pagination types, will be generated.

Additional
Support for swagger_auto_schema decorator of drf-yasg
JSON API schema is also generated for success responses (statuses 2XX) defined manually using responses argument
of swagger_auto_schema decorator.
Stripping write_only fields from response and read_only from request
drf_yasg_json_api.inspectors.InlineSerializerSmartInspector strips fields inaccessible in request/response to
provide view of fields that are really available to use.
You can revert to traditional drf-yasg view of all serializer fields in both response and request by replacing this
inspector with drf_yasg_json_api.inspectors.InlineSerializerInspector
Extra x-writeOnly and x-readOnly properties
drf_yasg_json_api.inspectors.XPropertiesFilter uses:

x-readOnly to mark read only fields even if they are nested
x-witeOonly adds missing support for write only fields

Coexistence of JSON API views with pure REST API views
JSON API docs will be generated by drf_yasg_json_api.inspectors.JSONAPISerializerInspector,
non JSON API views are ignored by this inspector.
Pure REST API docs will be generated by drf-yasg inspectors – either
drf_yasg.inspectors.ReferencingSerializerInspector or drf_yasg.inspectors.InlineSerializerInspector depending on
which one you prefer to use.
RecursiveField
RecursiveField follows different approach from JSON API, so it cannot be used with
JSONAPISerializerInspector, but you can still have pure REST API views that will be documented
using ReferencingSerializerInspector.
Alternatively, instead of RecursiveField you can use included_serializers
with self (e.g. included_serializers = {'related-obj': 'self'}) to implement limited in depth recursion
the JSON API way.
