apply_filters( 'wpcd_settings_welcome_text_initial', $ssh_welcome_text )
The first tab on the settings screen is the welcome tab and it shows a welcome message at the very top. You can replace this message using this filter.
Note that if the WPCD_SKIP_WELCOME_MESSAGE entry in wp-config.php is set to true, this text is not shown at all.
If you would like to always make sure your text is shown, use the wpcd_settings_welcome_text filter instead.
