 # Welcome to LlamaIndex 🦙 !
 
-LlamaIndex is a data framework for [LLM](https://en.wikipedia.org/wiki/Large_language_model)-based applications which benefit from context augmentation. Such LLM systems have been termed as RAG systems, standing for "Retrieval-Augemented Generation". LlamaIndex provides the essential abstractions to more easily ingest, structure, and access private or domain-specific data in order to inject these safely and reliably into LLMs for more accurate text generation. It's available in Python (these docs) and [Typescript](https://ts.llamaindex.ai/).
