## Getting Started

Once activated, the percentage column is immediately available in the advanced prices table for all products.

## Verification

The plugin is correctly installed if:

* The **Percentage** column appears in the advanced prices table
* Entering a percentage value automatically calculates and fills in the price
* The base toggle (sale price / purchase price) is visible next to the percentage field

## Uninstalling

1. Go to **Extensions → My Extensions**
2. Deactivate the plugin
3. Click **Uninstall**

When uninstalling, you have two options:

* **With "Remove all app data permanently":** The database table with all stored percentage values is completely removed. Absolute product prices are not affected.
* **Without this option:** The percentage data remains in the database. If you reinstall the plugin later, all previously configured percentage values will be available again.
