+# log4r
+
+A log4j-like logging framework for Rust.
+
+## Overview
+
+`log4r` is a simple, extensible logging framework inspired by log4j. It provides different log levels and an easy-to-use API for Rust applications.
+
+## Features
+
+- Multiple log levels (Trace, Debug, Info, Warn, Error)
+- Simple API similar to log4j
+- Thread-safe logging
+- Timestamped log entries
+- Configurable log levels
+
+## Installation
+
+Add this to your `Cargo.toml`:
+
+```toml
+[dependencies]
+log4r = "0.1"
+```
+
+## Example
+
+```rust
+use log4r::{LogLevel, Logger};
+
+fn main() {
+    // Initialize the logger with Debug level
+    Logger::init(LogLevel::Debug);
+    
+    // Test all log levels
+    log4r::trace!("This is a trace message - won't be printed");
+    log4r::debug!("This is a debug message - will be printed");
+    log4r::info!("This is an info message - will be printed");
+    log4r::warn!("This is a warning message - will be printed");
+    log4r::error!("This is an error message - will be printed");
+}
+```
