You're in. Here's what happens next.

1. Your licence key is in your email. Freemius sends it the moment payment clears, along with your invoice. Not there in a few minutes? Check spam, then email support@checknautpro.com.

2. Install Checknaut Pro beside the free plugin. Pro is a second plugin, not a replacement: the free Checknaut stays installed and active, and Pro adds the paid half on top of it. If you are not running the free plugin yet, install it first: download the zip from the free download (also the button on the home page) and upload it under Plugins → Add New → Upload Plugin. Its wordpress.org listing is pending, so searching Plugins → Add New will not find it yet. Or activate Pro first and press its Install Checknaut button, which installs the official download after checking its published checksum. Still on a 4.x version from before the rename? Install and activate Checknaut, then deactivate the old plugin: settings, the connector, OAuth clients, history and your licence carry over. Then download Pro below and upload it under Plugins → Add New → Upload and activate it. Both stay active. The FAQs cover installing and moving from 4.x. Nothing is overwritten, so your settings, pages, audit history and journal are untouched. WordPress 6.5+ and PHP 8.0+, any theme.

3. Paste the key. In wp-admin open Checknaut → Checknaut Pro and paste the key. Pro turns on for that site. The same key activates each site in your plan; the same panel releases a seat when a site retires.

4. Run your first audit. Checknaut → Audit → Run full audit. Every finding the plugin can repair gets a Fix button, journaled and undoable.
