+- Run open-source models on vLLM, we recommend starting with the [Quickstart Guide](./getting_started/quickstart.md)
+- Build applications with vLLM, we recommend starting with the [User Guide](./usage)
+- Build vLLM, we recommend starting with [Developer Guide](./contributing)

+# Examples
+
+vLLM's examples are split into three categories:
+
+- If you are using vLLM from within Python code, see [Offline Inference](./offline_inference/)
+- If you are using vLLM from an HTTP application or client, see [Online Serving](./online_serving/)
+- For examples of using some of vLLM's advanced features (e.g. LMCache or Tensorizer) which are not specific to either of the above use cases, see [Others](./others/)

 # Using vLLM
 
-vLLM supports the following usage patterns:
+First, vLLM must be [installed](../getting_started/installation) for your chosen device in either a Python or Docker environment.
+
+Then, vLLM supports the following usage patterns:
 
 - [Inference and Serving](../serving/offline_inference.md): Run a single instance of a model.
 - [Deployment](../deployment/docker.md): Scale up model instances for production.
