+Overridden Console Functions
+----------------------------
+The above log levels correspond to the following console functions:
+```javascript
+console.error
+console.warn
+console.log
+console.info
+console.debug
+```
+
+Unit testing and console.debug
+------------------------------
+Since console.debug is not a standard NodeJS function, you may run into problems in situations (such as in unit testing) where you do not want to initialize the Console-TEN module, yet your code may call console.debug.  To work around this, simply create a dummy console.debug function in a file such as console_init.js:
+```javascript
+console.debug = function(){};
+```
+Unit testing frameworks such as Mocha allow you to "--require" additional scripts when executing from the command line:
+```bash
+mocha -r "console_init" unit_test_file.js
+```
+
 Custom log format
 -----------------
 You can easily override or customize the format and the information appended to the console.log functions by passing a format function to the init method:

+Modify Express logs to match Console-TEN
+----------------------------------------
+If you use the Express web application framework, you'll want to modify the default log format for Express to match the format in Console-TEN so that your log files are readily parsable, this can easily be done with the following code:
+
+```javascript
+express.logger.token('zdate', function() { return new Date().toISOString(); });
+app.use(express.logger('[:zdate] [WEBLOG] :remote-addr - - ":method :url HTTP/:http-version" :status :res[content-length] ":referrer" ":user-agent"'));
+```
