+## Optional Dependencies
+
+By default LlamaIndex installs a core set of dependencies; we also provide a convenient way to install commonly-required optional dependencies. These are currently in three sets:
+
+- `pip install llama-index[local_models]` installs tools useful for private LLMs, local inference, and HuggingFace models
+- `pip install llama-index[postgres]` is useful if you are working with Postgres, PGVector or Supabase
+- `pip install llama-index[query_tools]` gives you tools for hybrid search, structured outputs, and node post-processing
