I'm having trouble getting it to work

1. Have you looked at the settings page (Settings->WP Tuner)? You'll find installer error notes there. Most common: your WP root folder needs write permission (at least 0755), and WP Tuner must be able to set permissions on your wp-config.php file to make it editable.
2. Are you logged in with Administrator permissions (level 10)? Normally, only admins see anything.
3. If you continue to have trouble, please set the Debug Level to 1, copy the wpTuner Diagnostics and paste them into an error report at my site.

How do I customize WP Tuner?

There's little reason to bother changing the CSS. This is an admin-only tool; your readers will not see anything. However, there's some CSS at the top of wptunershow.php, and further down in wptunersetup.php.

This is a fully translatable/localizable plugin. See the wptuner.pot file, and the online gettext tools such as poedit. Please send me your translations; I'll make them part of the distribution with credit to you!

How do I examine performance in more detail?

WP Tuner is an entire performance analysis toolkit. The built-in admin settings provide a set of default measures that can be enabled without manual intervention.

See the Advanced Use hints section for some examples
