 Loaders and readers allow you to easily ingest data for search and retrieval by a large language model, while tools allow the models to both read and write to third party data services and sources. Ultimately, this allows you to create your own customized data agent to intelligently work with you and your data to unlock the full capability of next level large language models.

+Llama-packs can be downloaded using the `llamaindex-cli` tool that comes with `llama-index`:
+
+```bash
+llamaindex-cli download-llamapack ZephyrQueryEnginePack --download-dir ./zephyr_pack

+Or with the `download_llama_pack` function directly:

+```python
+from llama_index.llama_packs import download_llama_pack

+# download and install dependencies
+LlavaCompletionPack = download_llama_pack(

 ### Step 1: Create a new directory
 
-For loaders, create a new directory in `llama_hub`, and for tools create a directory in `llama_hub/tools` It can be nested within another, but name it something unique because the name of the directory will become the identifier for your loader (e.g. `google_docs`). Inside your new directory, create a `__init__.py` file specifying the module's public interface with `__all__`, a `base.py` file which will contain your loader implementation, and, if needed, a `requirements.txt` file to list the package dependencies of your loader. Those packages will automatically be installed when your loader is used, so no need to worry about that anymore!

 ### Step 3: Add your loader to the library.json file
 
-Finally, add your loader to the `llama_hub/library.json` file (for tools, add them to the `llama_hub/tools/library.json`) so that it may be used by others. As is exemplified by the current file, add the class name of your loader or tool, along with its ID, author, etc. This file is referenced by the Llama Hub website and the download function within LlamaIndex.
