+# Whirl
+
+Whirl is a basic logging library for Haskell. I took on this project to teach
+myself the basics of Haskell and experience setting up a full library in the
+language.
+
+# Logger API Documentation
+
+The Logger module provides a simple logging functionality with support for different severity levels.
+
+## Types
+
+### LogLevel
+
+Represents the severity levels for log messages.
+
+```haskell
+data LogLevel = INFO | WARNING | ERROR | DEBUG deriving (Eq, Ord, Show)
+```
+
+### LogMessage
+
+Represents a log message with a severity level and a message.
+
+```haskell
+data LogMessage = LogMessage
+  { logLevel :: LogLevel  -- ^ Severity level of the log message.
+  , message  :: String    -- ^ The log message.
+  } deriving (Show)
+```
+
+### LoggerConfig
+
+Configuration for the logger.
+
+```haskell
+data LoggerConfig = LoggerConfig
+  { logConfigLevel :: LogLevel              -- ^ Minimum severity level to log.
+  , logCallback    :: LogMessage -> IO ()   -- ^ Callback function to handle log messages.
+  }
+```
+
+## Functions
+
+### defaultConfig
+
+Returns the default configuration for the logger.
+
+```haskell
+defaultConfig :: LoggerConfig
+```
+
+### initLogger
+
+Initializes a new logger with the given configuration.
+
+```haskell
+initLogger :: LoggerConfig -> IO Logger
+```
+
+### logMessage
+
+Logs a message with the specified severity level.
+
+```haskell
+logMessage :: Logger -> LogLevel -> String -> IO ()
+```
+
+### waitLogger
+
+Helper function to wait for a logger to finish.
+
+```haskell
+waitLogger :: Logger -> IO ()
+```
+
+## Example Usage
+
+```haskell
+Copy code
+-- Initialize logger with default configuration
+logger <- initLogger defaultConfig
+
+-- Log messages with different severity levels
+logMessage logger INFO "This is an informational message."
+logMessage logger WARNING "This is a warning message."
+logMessage logger ERROR "This is an error message."
+logMessage logger DEBUG "This is a debug message."
+
+-- Wait for the logger to finish
+waitLogger logger
+```
+
+This example demonstrates how to use the Logger API to initialize a logger, log messages with various severity levels, and wait for the logger to finish processing.
