-PageIndex is a revolutionary document processing system that uses **reasoning-based RAG** instead of traditional vector-based similarity search. Unlike conventional RAG systems that rely on semantic similarity, PageIndex uses multi-step reasoning and tree search to retrieve information like a human expert would.
-
-### Key Advantages over Vector-based RAG
+PageIndex is a vectorless **reasoning-based RAG** system which uses multi-step reasoning and tree search to retrieve information like a human expert would. It has the following properties:
 
-- **Higher Accuracy**: Relevance beyond similarity - ideal for domain-specific documents where semantics are similar
+- **Higher Accuracy**: Relevance beyond similarity -
 - **Better Transparency**: Clear reasoning trajectory with traceable search paths
 - **Like A Human**: Retrieve information like a human expert navigates documents
 - **No Vector DB**: No extra infrastructure overhead
 - **No Chunking**: Preserve full document context and structure
 - **No Top-K**: Retrieve all relevant passages automatically
 
-## Features
-
-- **Local PDF Processing**: Upload local PDF files directly without manual uploads
-- **URL Support**: Process documents from URLs
-- **Full PageIndex Integration**: Access all PageIndex capabilities (OCR, tree generation, reasoning-based retrieval)
-- **Secure OAuth Authentication**: OAuth 2.1 with PKCE and automatic token refresh
-- **TypeScript**: Full type safety with MCP SDK
-- **Desktop Extension (DXT)**: One-click installation for Claude Desktop with secure configuration
-
-## Usage
-
-### Getting Started
 
-The PageIndex MCP server uses OAuth 2.1 authentication for secure access. When you first run the server, it will guide you through the authentication process by opening your browser to authorize the application.

+# PageIndex MCP Setup 
+See [PageIndex MCP](https://pageindex.ai/mcp) for full video guidances.
 
-### For Claude Desktop (Recommended)
+### 1. For Claude Desktop (Recommended)
 
 **One-Click Installation with Desktop Extension (DXT):**
 
 1. Download the latest `.dxt` file from [Releases](https://github.com/VectifyAI/pageindex-mcp/releases)
 2. Double-click the `.dxt` file to install automatically in Claude Desktop
 3. The OAuth authentication will be handled automatically when you first use the extension
 
-**Benefits of DXT Installation:**
-
-- **No technical setup** - just download and double-click
-- **Secure OAuth authentication** - handled automatically through your browser
-- **Automatic updates** - extensions update seamlessly
-- **Full local PDF support** - upload and process PDFs directly from your computer
-
 This is the easiest way to get started with PageIndex's reasoning-based RAG capabilities.
