 <h3>Error Reporting</h3>
 
 <p>
-  Setting the <kbd>ENVIRONMENT</kbd> constant to a value of '<kbd>development</kbd>' will
-  cause all PHP errors to be rendered to the browser when they occur. Conversely,
-  setting the constant to '<kbd>production</kbd>' will disable all error output. Disabling
-  error reporting in production is a <a href="security.html">good security practice</a>.

 <h3>Configuration Files</h3>
 
 <p>
-  Optionally, you can have CodeIgniter load environment-specific
-  configuration files. This may be useful for managing things like differing API keys
-  across multiple environments. This is described in more detail in the
-  environment section of the <a href="../libraries/config.html#environments">Config Class</a> documentation.
