 [ASGI](https://asgi.readthedocs.io) (Asynchronous Server Gateway Interface) is a way to serve Python web applications making use of async I/O to achieve better performance. Some examples of ASGI frameworks include FastAPI, Django 3.0+, and Starlette. If you’re using one of these frameworks along with Elasticsearch then you should be using `~elasticsearch.AsyncElasticsearch` to avoid blocking the event loop with synchronous network calls for optimal performance.
 
-[Elastic APM](apm-agent-php://docs/reference/index.md) also supports tracing of async Elasticsearch queries just the same as synchronous queries. For an example on how to configure `AsyncElasticsearch` with a popular ASGI framework [FastAPI](https://fastapi.tiangolo.com/) and APM tracing there is a [pre-built example](https://github.com/elastic/elasticsearch-py/tree/master/examples/fastapi-apm) in the `examples/fastapi-apm` directory.
