 [LangGraph](https://python.langchain.com/docs/langgraph) is a library for building stateful, **multi-actor** applications, and being able to add cycles to LLM app. It is not a DAG. 
 
 Single and multi-agent flows are described and represented as graphs.
 
 ## Value propositions 
 
-* build stateful, multi-actor applications with LLMs
-* coordinate multiple chains or actors across multiple steps of computation in a cyclic manner
-* build plan of the actions to take
-* take the actions
-* observe the effects
-* support persistence to save state after each step in the graph. This allows human in the loop pattern
