 # Introduction
 
-**LangChain** is a framework for developing applications powered by language models. It enables applications that are:
-- **Data-aware**: connect a language model to other sources of data
-- **Agentic**: allow a language model to interact with its environment
+**LangChain** is a framework for developing applications powered by language models. It enables applications that:
+- **Are context-aware**: connect a language model to other sources of context (prompt instructions, few shot examples, content to ground it's response in)
+- **Reason**: rely on a language to reason (about how to answer based on provided context, what actions to take, etc)
 
 The main value props of LangChain are:
 1. **Components**: abstractions for working with language models, along with a collection of implementations for each abstraction. Components are modular and easy-to-use, whether you are using the rest of the LangChain framework or not
