 2. Activate the plugin through the 'Plugins' menu in WordPress
-3. A default form is automatically created on activation
-
-## Usage
-
-### Displaying a Form
-
-Use the shortcode to display a registration form on any page or post:
-
-```
-[go_form id=1]
-```
-
-Replace `1` with your form ID. Find form IDs in the admin settings page.
-
-### Admin Settings
-
-Navigate to **Go Form** in the WordPress admin menu to:
-
-- **Create Forms** - Add new registration forms with names
-- **Manage Forms** - View all forms with their shortcodes and IDs
-- **View Entries** - See all submissions for a form in a sortable table
-- **Edit Entries** - Modify existing player registrations
-- **Delete Entries** - Remove individual registrations
-- **Delete Forms** - Remove a form and all its entries (cascading delete)
-- **Export Data** - Download entries in various tournament formats
-- **Manage Custom Fields** - Add, edit, and delete custom fields per form
-- **EGD Data Sync** - Update rank and rating from EGD for all entries with EGD numbers
-
-### EGD Search
-
-Players can click the "Search EGD" button on the frontend form to look up their information in the European Go Database. This auto-fills:
-- First Name
-- Last Name

-- `wp_go_form_entry_custom_values` - Stores custom field values for each entry
-
-All tables use foreign keys with CASCADE delete and are automatically removed when the plugin is uninstalled.
