+### Cobalt.Logger.File ###
+
+This logger communicates a file via a writable stream, and is intended
+only for node. Like the JSConsole logger, you can also initialize it with
+a formatter to convert the log object to a string:
+
+```
+ new Cobalt.Logger.File({
+     formatter : Cobalt.Formatter.Token,

+         formatString : "[{{_timestamp}}] {{message}} (@{{_from}})"

+This is the lazy formatter, it just outputs the string in the following

+
+```
+'[{{_timestamp}}][{{_logLevelString}}]{{_from}}: {{_message}}'
+```
+
+Where `_timestamp` is converted to ISO.

 ### Cobalt.Formatter.Token ###
 
-The Token formatter is a very simple formatter that uses a formatString to
-extract values from the log object and interpolate them in a string.
+The Token formatter is a more advanced, but still fairly simple
+formatter. It takes a `formatString` and interpolates the properties
+of the object. By default it transforms anything inside double curly
+braces `{{likeThis}}`, however you can set a custom `replaceRule`.

+#### Accepted Options ####
+
+* `formatString` : The string used to replace. Defaults to `"{{message}}"`
+* `replaceRule` : The regex rule to use for replacement of tokens in the
+  formatString. Defaults to `/{{(.*?)}}/g`
+* `separatorLength` <Number> : How long to print separators. Defaults to 60.
+* `isoDate` <Boolean> : Whether or not to convert `_timestamp` to ISO
+  date. Defaults to true.
+* `separatorType` <String> : The string to use for the separator.
+  Defaults to `"="`
+* `ansiColor` <Boolean> : Whether to use ANSI colors for output.
+  Defaults to `false`. This options depends on `colors`
