+
+## Use instrumentation libraries
+
+If a library does not ship with native OpenTelemetry support, you can use
+[instrumentation libraries](/docs/specs/otel/glossary/#instrumentation-library)
+to generate telemetry data for a library or framework.
+
+For example,
+[the instrumentation library for HTTPX](https://pypi.org/project/opentelemetry-instrumentation-httpx/)
+automatically creates [spans](/docs/concepts/signals/traces/#spans) based on
+HTTP requests.
+
+## Setup
+
+You can install each instrumentation library separately using pip. For example:
+
+```sh
+pip install opentelemetry-instrumentation-{instrumented-library}
+```
+
+In the previous example, `{instrumented-library}` is the name of the
+instrumentation.
+
+To install a development version, clone or fork the
+`opentelemetry-python-contrib` repository and run the following command to do an
+editable installation:
+
+```sh
+pip install -e ./instrumentation/opentelemetry-instrumentation-{integration}
+```
+
+After installation, you will need to initialize the instrumentation library.
+Each library typically has its own way to initialize.
+
+## Example with HTTPX instrumentation
+
+Here's how you can instrument HTTP requests made using the `httpx` library.
+
+First, install the instrumentation library using pip:
+
+```sh
+pip install opentelemetry-instrumentation-httpx
+```
+
+Next, use the instrumentor to automatically trace requests from all clients:
+
+```python
+import httpx
+from opentelemetry.instrumentation.httpx import HTTPXClientInstrumentor
+
+url = "https://some.url/get"
+HTTPXClientInstrumentor().instrument()
+
+with httpx.Client() as client:
+     response = client.get(url)
+
+async with httpx.AsyncClient() as client:
+     response = await client.get(url)
+```
+
+### Turn off instrumentations
+
+If needed, you can uninstrument specific clients or all clients using the
+`uninstrument_client` method. For example:
+
+```python
+import httpx
+from opentelemetry.instrumentation.httpx import HTTPXClientInstrumentor
+
+HTTPXClientInstrumentor().instrument()
+client = httpx.Client()
+
+# Uninstrument a specific client
+HTTPXClientInstrumentor.uninstrument_client(client)
+
+# Uninstrument all clients
+HTTPXClientInstrumentor().uninstrument()
+```
+
+## Available instrumentation libraries
+
+A full list of instrumentation libraries produced by OpenTelemetry is available
+from the [opentelemetry-python-contrib][] repository.
+
+You can also find more instrumentations available in the
+[registry](/ecosystem/registry/?language=python&component=instrumentation).
+
+## Next steps
+
+After you have set up instrumentation libraries, you might want to add your own
+[instrumentation](/docs/languages/python/instrumentation) to your code, to
+collect custom telemetry data.
+
+You might also want to configure an appropriate exporter to
+[export your telemetry data](/docs/languages/python/exporters) to one or more
+telemetry backends.
+
+You can also check the
+[automatic instrumentation for Python](/docs/languages/python/automatic).
