+# HLog - v0.10.2
+
+A structured logging package for Go built on top of [zerolog](https://github.com/rs/zerolog). HLog provides simple configuration via environment variables, flexible output options, and automatic log file management.
+
+## Features
+
+- Multiple output modes: console, file, or both simultaneously
+- Configurable log levels: trace, debug, info, warn, error, fatal, panic
+- Environment variable-based configuration with ConfigFromEnv
+- Automatic log file management with append or overwrite modes
+- Built on zerolog for high performance and structured logging
+- Error stack trace support via pkg/errors integration
+- Unix timestamp format
+- Console-friendly output formatting
+- Multi-writer support for simultaneous console and file output
+
+## Installation
+
+```bash
+go get git.haelnorr.com/h/golib/hlog
+```
+
+## Quick Start
+
+```go
+package main
+
+import (
+	"log"
+	"os"
+
+	"git.haelnorr.com/h/golib/hlog"
+)
+
+func main() {
+	// Load configuration from environment variables
+	cfg, err := hlog.ConfigFromEnv()
+	if err != nil {
+		log.Fatal(err)
+	}
+
+	// Create a new logger
+	logger, err := hlog.NewLogger(cfg, os.Stdout)
+	if err != nil {
+		log.Fatal(err)
+	}
+	defer logger.CloseLogFile()
+
+	// Start logging
+	logger.Info().Msg("Application started")
+	logger.Debug().Str("user", "john").Msg("User logged in")
+	logger.Error().Err(err).Msg("Something went wrong")
+}
+```
