 # Overview
 
-**Eino['aino]** (pronounced as "I know") aims to be the ultimate LLM application development framework in Golang. Drawing inspirations from many excellent LLM application development frameworks in the open-source community such as LangChain & LlamaIndex, etc., as well as learning from cutting-edge research and real world applications, Eino offers an LLM application development framework that emphasizes on simplicity, scalability, reliability and effectiveness that better aligns with Golang programming conventions.

 - a carefully curated list of **component** abstractions and implementations that can be easily reused and combined to build LLM applications

 ## Highly Extensible Aspects (Callbacks)
 
 - Aspects handle cross-cutting concerns such as logging, tracing, metrics, etc., as well as exposing internal details of component implementations.
-- Five aspects on supported: **OnStart, OnEnd, OnError, OnStartWithStreamInput, OnEndWithStreamOutput**.
+- Five aspects are supported: **OnStart, OnEnd, OnError, OnStartWithStreamInput, OnEndWithStreamOutput**.
 - Developers can easily create custom callback handlers, add them during graph run via options, and they will be invoked during graph run.
 - Graph can also inject aspects to those component implementations that do not support callbacks on their own.
