+Codegen Sample Guide
+#####################
+
+.. note:: This guide is in its early development and is a work-in-progress with
+   placeholder content.
+
+Overview
+********
+
+The CodeGen example uses specialized AI models that went through training with datasets that 
+encompass repositories, documentation, programming code, and web data. With an understanding 
+of various programming languages, coding patterns, and software development concepts, the 
+CodeGen LLMs assist developers and programmers. The LLMs can be integrated into the developers' 
+Integrated Development Environments (IDEs) to have more contextual awareness to write more 
+refined and relevant code based on the suggestions. 
+
+Purpose
+*******
+* Code Generation: Streamline coding through Code Generation, enabling non-programmers to describe tasks for code creation.
+* Code Completion: Accelerate coding by suggesting contextually relevant snippets as developers type.
+* Code Translation and Modernization: Translate and modernize code across multiple programming languages, aiding interoperability and updating legacy projects.
+* Code Summarization: Extract key insights from codebases, improving readability and developer productivity.
+* Code Refactoring: Offer suggestions for code refactoring, enhancing code performance and efficiency.
+* AI-Assisted Testing: Assist in creating test cases, ensuring code robustness and accelerating development cycles.
+* Error Detection and Debugging: Detect errors in code and provide detailed descriptions and potential fixes, expediting debugging processes.
+
+How It Works
+************
+
+The CodeGen example uses an open-source code generation model with Text Generation Inference (TGI) 
+for serving deployment. It is presented as a Code Copilot application as shown in the diagram below.
