-# 📦 Packets – Custom Package Manager for Linux
-
-> A fast and minimal package manager written in Go with Lua hooks, local network discovery, and SQLite-based indexing.
-
----
-
-## 📘 Overview
-
-**Packets** is a lightweight package manager for Linux, written in Go. It supports:
-
-- Installation and removal of packages
-- Dependency resolution and upgrading
-- `.tar.zst` compressed packages with `manifest.toml` metadata
-- Lua-based install/remove hooks
-- Local cache with SHA-256 validation
-- Peer-to-peer discovery over LAN
-- Remote package syncing via HTTP
-- SQLite-based local database
-

-
-## 📁 Directory Structure
-
-| Path                  | Description                      |
-|-----------------------|----------------------------------|
-| `/etc/packets/`       | Configuration files              |
-| `/opt/packets/`       | Installed package data           |
-| `/var/cache/packets/` | Cached `.tar.zst` package files  |
-
-(This can be changed in `/etc/packets/config.toml`)

-# Available Commands

-| Command                   | Description                                                                |
-|---------------------------|----------------------------------------------------------------------------|
-|`packets install <name>`	|    Install a package (resolves dependencies, executes Lua install hook)    |
-|`packets remove <name>`	|    Remove a package (executes Lua remove hook)                             |
-|`packets upgrade <name>`	|    Upgrade a package by checking family and serial in the manifest         |
-|`packets sync [url]`	    |    Synchronize index.db from remote HTTP source                            |
-|`packets serve init/stop`  |    Starts and stop the LAN service daemon                                  |
-|`packets list`	            |    List all installed packages                                             |
-|`packets info`             |    Get technical package information                                       |
-|`packets search`           |    List all packages in index.db                                           |
-
-# 📦 Package Format
-
-Packages must be compressed as .tar.zst and include:
-
-
-- ├── manifest.toml       # Package metadata
-- ├── data/               # Files to install
-- ├── install.lua         # Lua install hook
-- └── remove.lua          # Lua remove hook
-
-
-## Example manifest.toml
-    [Info]
-     name = "packets"
-     version = "1.0.0"
-     description = "offline and online packetmanager"
-     dependencies = []
-     author = "robo"
-     family = "1f84ca15-5077-4f1d-a370-0ec860766eb2"
-     serial = 0
-
-    [Hooks]
-     install = "install.lua"
-     remove = "remove.lua"
-
---
-# 🔄 Installation Process
-
-- Check if package is already cached and validated via SHA-256.
-
-- If not, search the package:
-
-    Via LAN: Sends UDP broadcast (Q:filename) to peers.
-
-    Via HTTP: Downloads from configured mirrors.
-
-    Decompress .tar.zst, install files.
-
-    Execute Lua install hook.
-
-# 🧩 Core Features
-✅ Dependency Resolution
-
-Installs required dependencies listed in the manifest.
-## 🌐 LAN Discovery
-
-Broadcasts package request to devices in the same network via UDP.
-## 📡 Remote Download
-
-Downloads package via HTTP if not found on LAN.
-## 🔒 Security
-
-    SHA-256 checksum validation
-
-    Path validation to avoid exploits (..)
-
-    Safe, sandboxed Lua runtime with limited API
-
-
-# 🌍 Global Variables Available in Lua Scripts
-
-During the execution of install.lua and remove.lua hooks, some global variables are automatically provided to the Lua environment. These help simplify file path handling and access to package-specific directories.
-## Available variables:
-
-|Name	             |Type	  |  Description
-|--------------------|--------|--------------------------------------------------------------------------|
-|packets_package_dir |	string|	Absolute path to the package's data directory (e.g., /opt/packets/...)   | 
-| packets_bin_dir      |  string| Path where executables should be installed (e.g., /usr/bin)            |
-|script              |  string|	Path to the currently executing script (e.g., "install.lua")             |
-|data_dir            |  string|	Path to the /data folder of the current package                          |
-### Example usage in Lua:
-
-        print("Installing into: " .. packets_bin_dir)
-        print("Package data in: " .. data_dir)
-
-        -- Copy a binary to /usr/bin
-        os.copy(path_join(data_dir, "htop"), path_join(packets_bin_dir, "htop"))
-
-These variables are preloaded in the Lua environment—no need to manually declare or initialize them.
-
-
-## 🛠️ Allowed Lua API (install/remove hooks)
-
-To ensure security, only a limited set of safe functions are exposed in Lua hooks:
-
-    os.remove(path)
-    os.rename(old, new)
-    os.copy(source, target)
-    os.symlink(source, target)
-    io.open(path, mode)
-    os.mkdir(path, filemode)
-    path_join(...) 
-
-### Note: Dangerous functions like os.execute, os.getenv, etc. are removed.
-## 🗃️ Databases
-
-    index.db: Available packages (after sync)
-
-    installed.db: Packages currently installed
-
-# ⚠️ Restrictions & Notes
-
-    Linux only (//go:build linux)
-
-    Root permissions required for most commands
-
-    Changing dataDir triggers prompt to migrate installed packages
-
-    Binaries in binDir are not automatically moved if path changes
-
-    Do not manually edit lastDataDir
-
-
-# TODO
-
-- Auto upgrade all packages available
-- Packets Universe
