+ABCoder, an AI-oriented Code-processing **Framework**, is designed to enhance and extend the coding context for Large-Language-Model (LLM), finally boosting the development of AI-assisted-programming applications. 
 
 
 ## Features
 
-- Universal Abstract-Syntax-Tree (UniAST), an language-independent, AI-friendly specification of code information, providing a boundless, flexible and structrual coding context for both AI and hunman.

-- General Writer, transforms UniAST back to codes.

 - **Code-Retrieval-Augmented-Generation (Code-RAG)**, provides a set of MCP tools to help the LLM understand code repositories precisely and locally. And it can support both in-workspace and out-of-workspace third-party libraries simultaneously -- I guess you are thinking about [DeepWiki](https://deepwiki.org) and [context7](https://github.com/upstash/context7), but ABCoder is more reliable and confidential -- no need to wait for their services to be done, and no worry about your codes will be uploaded! 
 
-Based on these features, developers can easily implement or enhance their AI-assisted-programming applications, such as reviewing, optimizing, translating, etc.
