+# OpenLLMetry
+
+OpenLLMetry from [Traceloop](https://www.traceloop.com/) is a set of extensions built on top of [OpenTelemetry](https://opentelemetry.io/) that gives you complete observability over your LLM application.
+
+OpenLLMetry supports instrumenting the `qdrant_client` Python library and exporting the traces to various observability platforms, as described in their [Integrations catalog](https://www.traceloop.com/docs/openllmetry/integrations/introduction#the-integrations-catalog).
+
+This page assumes you're using `qdrant-client` version 1.7.3 or above.
+## Usage
+
+To set up OpenLLMetry, follow these steps:
+
+1. Install the SDK:
+
+```console
+pip install traceloop-sdk
+```
+
+1. Instantiate the SDK:
+
+```python
+from traceloop.sdk import Traceloop
+
+Traceloop.init()
+```
+
+You're now tracing your `qdrant_client` usage with OpenLLMetry!
+
+## Without the SDK
+
+Since Traceloop provides standard OpenTelemetry instrumentations, you can use them as standalone packages. To do so, follow these steps: 
+
+1. Install the package:
+
+```console
+pip install opentelemetry-instrumentation-qdrant
+```
+
+1. Instantiate the `QdrantInstrumentor`.
+
+```python
+from opentelemetry.instrumentation.qdrant import QdrantInstrumentor
+
+QdrantInstrumentor().instrument()
+```
