 # YNS Package Manager
 
-A lightweight package manager for Linux that uses a single repository source.
+Simple package manager for Linux. Uses JSON for package definitions.
 
-## Dependencies
+## Build
 
-- CMake (>= 3.10)
+Install dependencies:
-- C++17 compiler
-- libcurl
-- nlohmann-json
-
-On Ubuntu/Debian, you can install the dependencies with:
 ```bash
-sudo apt-get install build-essential cmake libcurl4-openssl-dev nlohmann-json3-dev
+sudo apt-get install build-essential cmake libssl-dev zlib1g-dev nlohmann-json3-dev
 ```
 
-## Building
+We build our own curl because the system's libcurl is usually only available as a dynamic library. Building our own lets us:
+- Create a static binary that works everywhere
+- Include only the features we need (HTTP support)
+- Avoid dependency problems during static linking
 
+Build steps:
 ```bash
-mkdir build
+# Get the code
-cd build
+git clone https://github.com/spitkov/ynspkg.git
+cd ynspkg
+
+# Build static curl
+chmod +x build_curl.sh
+./build_curl.sh
+
+# Build yns
+mkdir build && cd build
 cmake ..
 make
 ```
 
-## Installation
-
-After building, you can install the package manager with:
-```bash
-sudo make install
-```
-
-This will:
-- Install the `yns` binary to `/usr/local/bin`
-- Create necessary directories:
-  - `/var/cache/yns/` - For package cache
-  - `/var/lib/yns/` - For installed package database
-
 ## Usage
 
-### Update package cache
 ```bash
-yns update
+yns update              # Update package cache
+yns install <package>   # Install package
+yns remove <package>    # Remove package
+yns upgrade <package>   # Upgrade package
+yns list               # List packages
+yns debug              # Show debug info
+yns interactive        # Interactive mode
+yns version            # Show YNS version
+yns updateyns          # Update YNS to latest version
 ```
 
-### Install a package
+## Package Format
-```bash
-yns install <package_name>
-```
 
-### Remove a package
+```json
-```bash
+{
-yns remove <package_name>
+  "packages": {
-```
+    "package-name": {
-
+      "version": "1.0.0",
-### Upgrade a package
+      "description": "Package description",
-```bash
+      "install_script": "#!/bin/bash\n# Installation commands"
-yns upgrade <package_name>
+    }
-```
+  }
-
+} 
-### List all packages
-```bash
-yns list
-```
-
-### Interactive Mode
-```bash
-yns interactive
-```
-
-Interactive mode provides a shell-like interface where you can execute multiple commands without the `yns` prefix. Available commands in interactive mode:
-
-- `help` - Show available commands
-- `update` - Update package cache
-- `install <package>` - Install a package
-- `remove <package>` - Remove a package
-- `upgrade <package>` - Upgrade a package
-- `list` - List all packages
-- `clear` - Clear the screen
-- `exit` - Exit interactive mode
-
-Example interactive session:
-```
-$ yns interactive
-YNS Package Manager Interactive Mode
-Type 'help' for available commands or 'exit' to quit
-yns> update
-[100%] Package cache updated successfully
-yns> list
-Available packages:
-==================
-calc [installed 1.1, update available 2.0]
-notepad [available 2.0]
-yns> install notepad
-[50%] Installing notepad@2.0
-notepad@2.0 installed successfully
-yns> exit
-Goodbye!
-```
-
-## Color Coding
-
-The package manager uses color-coded output for better visibility:
-
-🔵 Blue:
-- Progress indicators (e.g., "[50%] Installing package...")
-- Available but not installed packages in `yns list`
-- Interactive mode prompt
-
-🟢 Green:
-- Success messages
-- Installed packages that are up to date in `yns list`
-- Interactive mode welcome message
-
-🟡 Yellow:
-- Installed packages with updates available in `yns list`
-
-🔴 Red:
-- Error messages
-
-Example `yns list` output:
-```
-Available packages:
-==================
-calc [installed 1.1, update available 2.0]    # Yellow
-notepad [available 2.0]                       # Blue
-vim [installed 3.0]                           # Green
-```
-
-## Repository Structure
-
-The package manager uses a single repository source at:
-`https://raw.githubusercontent.com/spitkov/ynsrepo/refs/heads/main/repo.json`
-
-The repository contains package information in JSON format, including:
-- Package name
-- Version
-- Installation script URL
-- Update script URL
-- Remove script URL
-
-## Features
-
-- Colored terminal output
-- Progress indicators
-- Automatic package cache management
-- Version tracking for installed packages
-- Secure script execution
-- Error handling and recovery
-- Interactive shell mode
