 # Caterpillar
 
-Caterpillar is a simple but powerful intuitive console logger for [Node.js](http://nodejs.org/). It supports grouping of messages, filtering log levels, colors, times, modules, custom formatters and custom transports.
+[![Build Status](https://secure.travis-ci.org/bevry/caterpillar.png?branch=master)](http://travis-ci.org/bevry/caterpillar)
+[![NPM version](https://badge.fury.io/js/caterpillar.png)](https://npmjs.org/package/caterpillar)
+[![Flattr this project](https://raw.github.com/balupton/flattr-buttons/master/badge-89x18.gif)](http://flattr.com/thing/344188/balupton-on-Flattr)
 
+Caterpillar is the ultimate logging system for Node.js, based on [transform streams](http://nodejs.org/api/stream.html#stream_class_stream_transform) you can log to it and pipe the output off to different locations, including [some pre-made ones](http://npmjs.org/keyword/caterpillar-transform). Caterpillar also supports log levels according to the [RFC standard](http://www.faqs.org/rfcs/rfc3164.html), as well as line, method, and file fetching for messages.
 
-## Example
 
-### Running Normally
 
-Running the [console example](https://github.com/bevry/caterpillar/blob/master/example/console.coffee#files) with `coffee examples/console.coffee`
+## Install
 
+### Backend
+
+1. [Install Node.js](http://bevry.me/node/install)
+2. `npm install --save caterpillar`
+
+### Frontend
+
+1. [See Browserify](http://browserify.org/)
+
+
+
+## Usage
+
+### Example with the [Filter](https://github.com/bevry/caterpillar-filter) and [Human](https://github.com/bevry/caterpillar-filter) transforms
+
+``` javascript
+// Import
+var level  = process.argv.indexOf('-d') === -1 ? 6 : 7;
+var logger = new (require('./').Logger)({level:level});
+var filter = new (require('caterpillar-filter').Filter)();
+var human  = new (require('caterpillar-human').Human)();
+
+// Pipe logger output to filter, then filter output to stdout
+logger.pipe(filter).pipe(human).pipe(process.stdout);
+
+// Log messages
+logger.log('emergency', 'this is level 0');
+logger.log('emerg', 'this is level 0');
+logger.log('alert', 'this is level 1');
+logger.log('critical', 'this is level 2');
+logger.log('crit', 'this is level 2');
+logger.log('error', 'this is level 3');
+logger.log('err', 'this is level 3');
+logger.log('warning', 'this is level 4');
+logger.log('warn', 'this is level 4');
+logger.log('notice', 'this is level 5');
+logger.log('note', 'this is level 5');
+logger.log('info', 'this is level 6');
+logger.log('default', 'this is level 6');
+logger.log('debug', 'this is level 7');
+logger.log('this is level 6, the default level');
+logger.log('you','can','also','use','as','many','arguments','as','you','want',1,[2,3],{four:5});
+```
+
+Result with log level 6 (info):
+
 <img src="https://github.com/bevry/caterpillar/raw/master/media/caterpillar-normal.png"/>
 
 
-### Running in Debug Mode (log level 7)
+Result with log level 7 (debug):
 
-Running the [console example](https://github.com/bevry/caterpillar/blob/master/example/console.coffee#files) with `coffee examples/console.coffee -d`
+<img src="https://github.com/bevry/caterpillar/raw/master/media/caterpillar-normal.png"/>
 
-When you set the log level to level 7 (debug level), then the `ConsoleFormatter` will also output a debug line, containing the time, file, function and line number of what triggered the log message
 
-<img src="https://github.com/bevry/caterpillar/raw/master/media/caterpillar-debug.png"/>
+### Transform API, extends [stream.Transform](http://nodejs.org/api/stream.html#stream_class_stream_transform)
 
+``` javascript
+new (require('caterpillar').Transform)(config)
+```
 
-## Using
+- Methods
+	- `constructor(config?)` create our new filter instance with the config, config is optional
+	- `pipe(child)` pipe our stream to the child, also sync our config to it
+	- `setConfig(config)` set the configuration and emit the `config` event
+	- `getConfig()` get the configuration
+	- `format(entry)` format the caterpillar logger entry
+- Configuration
+	- none by default
+- Events
+	- `config(config)` emitted once our configuration has updated
 
-Refer to the [console example](https://github.com/bevry/caterpillar/blob/master/example/console.coffee#files) for usage
 
+### Logger API, extends Transform API
 
-## Install
+``` javascript
+new (require('caterpillar').Logger)(config)
+```
 
-1. [Install Node.js](http://bevry.me/node/install)
+- Methods
+	- `constructor(config?)` create our new filter instance with the config, config is optional
+	- `log(args...)` write a log message, the first argument is suppose to be the level (will use the default level if it isn't)
+	- `format(level, args...)` create a log entry ready for writing to the logger stream, output is as follows:
 
-1. Install Caterpillar
+		``` javascript
+		{
+			"args": ["this is emergency and is level 0"],
+			"date": "2013-04-25T10:18:25.722Z",
+			"levelNumber": 0,
+			"levelName": "emergency",
+			"line": "59",
+			"method": "Task.fn",
+			"file": "/Users/balupton/Projects/caterpillar/out/test/caterpillar-test.js"
+		}
+		```
 
-	```
-	npm install caterpillar
-	```
+	- `getLevelNumber(name)` get the level number for the level name
+	- `getLevelName(number)` get the level name for the level number
+	- `getLevelInfo(nameOrNumber)` get the level name and number for either a level name or number
+	- `getLineInfo()` get the file, method, and line that the `log` method was called on
 
+- Configuration
+	- `levels` the level names and their associated number, also includes `default` for when no level was specified, defaults to:
+	
+		``` javascript
+		{
+			emergency: 0,
+			alert: 1,
+			critical: 2,
+			error: 3,
+			warning: 4,
+			notice: 5,
+			info: 6,
+			debug: 7,
 
+			emerg: 0,
+			crit: 2,
+			err: 3,
+			warn: 4,
+			note: 5,
+
+			default: 6
+		}
+		```
+
+- Events
+	- only those inherited
