-# Introduction
+# Quick Start: Callgent.com - Callable Agent
 
 Welcome to the new era of AI software development! But what does that really mean? Let's break it down.
 
-## The Core of AI Development
+## The Core of Software Development
+
+The hardest part of software development may be how to clearly describe the real **requirements**. Instead of writing code from scratch based on ambiguous and complex PRD, yet another approach we propose here, is to let real end users to interact with software more freely and intelligently.
+
+## The Extents to AI Code Generation
 
-The hard core of software development is all about clearly describing **requirements**. Currently we don't think it's realistic to expect AI to generate an entire software project from scratch.
+So, how do we leverage AI in software development?
 
-## Best Practices for AI Code Generation
+In essence, we strive to make every software service akin to a collaborative teammate, while empowering each user to function like a service in a programming context. To break the silos between users and systems.
 
-So, how do we leverage AI in software development? The best practice is to decide to what extent we want to auto-generate code by AI. Here are the levels to consider:
+To adhere to best practices, we may determine to what extent we want to auto-generate code by AI. Here are the levels to consider:
 
 - Machine code/ASM level
 - C/Java/Python/.. language level
 - Service orchestration level
 - Function-calling level
   - AI knows which and how to invoke an API
 - Callable Agent level
+  - function-calling outside of chatbox
 
 ## Introducing Callgent.com - Callable Agent
 
-Similar to function-calling, Callgent.com - Callable Agent takes it a step further. We're not just stuck function-calling in a chatbox anymore; we're now in native scenarios.
+Similar to function-calling, Callgent takes it a step further. We're not just stuck function-calling in a chatbox, we put callgents in all native scenarios, to let users and systems to call it the most natural way.

 ## The Real Meaning of the New Era of AI Development
 
 The true essence of this new era is to make AI more human-like and more human-friendly.
 
-With Callgent.com - Callable Agent, you can now:
+With Callgent, you can now:
 
-- **Interact with AI in a more natural way.** No more being confined to a chatbox. AI is now integrated into your native scenarios.
-- **Leverage AI for code generation.** Decide the level of code generation that suits your needs and let AI do the heavy lifting.
-- **Create software that is more human-friendly.** With AI that understands and interacts in a more human-like way, your software will be more intuitive and user-friendly.
+- **Interact with services in a more natural way.** you needn't describe your requirements, and wait for some developers to build it for you, just talk to services directly.
+- **Leverage AI for code generation.** AI agents stand between you and services to help understand and interact with them.
+- **Free and native experiences.** just like group chatting, requirements are expressed in natural language, and the AI agent will generate calling code and execute it for you.
