+# Logger
+
+Logger is a very simple logging library for node.js.
+
+## Installation
+
+Install like any other NPM library:
+
+```
+npm install --save logger
+```
+
+## Usage
+
+```
+var logger = require("logger");
+```
+
+Logger has 4 methods for logging:
+
+```
+logger.info("foo");   // yyyy/mm/dd HH:MM:SS INFO: foo
+logger.notice("foo"); // yyyy/mm/dd HH:MM:SS NOTICE: foo
+logger.warn("foo");   // yyyy/mm/dd HH:MM:SS WARNING: foo
+logger.die("foo");    // yyyy/mm/dd HH:MM:SS ERROR: foo
+```
+
+After logger.die, the process will immediately exit.
+
+If an error object is passed instead of a string, a stack trace will be printed, like this:
+
+```
+logger.notice(new Error("foo"));
+
+// yyyy/mm/dd HH:MM:SS NOTICE: foo - stack trace:
+// Trace: [Error: foo]
+//     <stack trace>
+```
+
+To set a different color theme, use `setTheme`:
+
+```
+logger.setTheme({
+	timestamp: "green"
+})
+```
+
+The available properties for setTheme is:
+
+* timestamp: timestamp, default: "blue"
+* level_0: logger.info, default: "grey"
+* level_1: logger.notice, default: "yellow"
+* level_2: logger.warn, default: "red"
+* level_3: logger.die, default: ["bold", "red"]
+
+The available values for themes are listed here: npmjs.com/package/colors
