 # agx
 
-wip
+***agx*** is a desktop application built with Tauri and SvelteKit that provides a modern interface for exploring and querying data using ClickHouse's embedded database engine (chdb).
 
-## how to
+## Features
 
+- Native desktop application performance with web technologies
+- Interactive SQL query editor with syntax highlighting
+- Schema browser for exploring data structure
+- Results displayed in a tabular format
+- Support for drag & drop file operations
+- Cross-platform compatibility (macOS, Linux, Windows)
+
+## Prerequisites
+
+- Node.js (v16 or later)
+- Rust toolchain
+- System dependencies for Tauri
+
+## Getting Started
+
+1. Clone the repository:
+```bash
+git clone https://github.com/agnosticeng/agx
+cd agx
 ```
+
+2. Download and setup chdb library:
+```bash
 ./src-tauri/update_libchdb.sh
 ```
 
+3. Install dependencies:
+```bash
+npm install
 ```
-npm i
+
+4. Run in development mode:

+## Development
+
+- The frontend is built with SvelteKit, offering a reactive and efficient UI
+- The backend uses Tauri with Rust, providing native performance and security
+- Communication between frontend and backend happens through Tauri's IPC bridge
+- Data querying is handled by chdb, an embedded ClickHouse engine
