Enable the extension key `barrierefrei_space`. 2. Run database updates in the Install Tool or Maintenance module. 3. Include the static TypoScript template `ALT Text Generator`. 4.

Database updates add these fields to `sys_file_reference`: - `tx_barrierefrei_space_style` - `tx_barrierefrei_space_seo_keywords` Extension Configuration ----------------------- [](#extension-configuration) TYPO3 backend path: `Settings -> Extension Configuration -> barrierefrei_space` Available setting: - `licenseKey`: license key for the current site subscription The service endpoint is built in and hidden from Extension Configuration. The Site URL is resolved from the current TYPO3 site configuration and cannot be edited in Extension Configuration. Make sure your site base URL is configured correctly in TYPO3. ALT Text Generation ------------------- [](#alt-text-generation) Open a TYPO3 record that contains an image reference. The extension adds a magic wand control next to the Alternative Text field.

Donation Widget --------------- [](#donation-widget) The extension provides a frontend content element: `Donation Widget` CType: `barrierefreispace_donationwidget` The widget shows only the total amount donated to charity for this site's subscription and links to: The amount is fetched from the API using the configured `licenseKey` and the resolved TYPO3 Site URL. ### Widget Position [](#widget-position) In the content element Appearance tab, only these layout choices are available: - Fixed bottom left - Fixed bottom right The widget is intentionally compact and fixed-position so it can communicate charity impact without taking over the page layout. Internationalization -------------------- [](#internationalization) Language files: - English: `Resources/Private/Language/locallang.xlf` - German: `Resources/Private/Language/de.locallang.xlf` The backend UI follows the TYPO3 backend user language.

Check: - Site Management -> Sites - The site's configured base URL - Reverse proxy / HTTPS headers, if TYPO3 runs behind a proxy ### License status does not update [](#license-status-does-not-update) Check: - `licenseKey` is saved in Extension Configuration - TYPO3 can reach the API over HTTPS - The displayed Site URL matches the site used for the subscription - TYPO3 caches were cleared after configuration changes ### Donation Widget is not visible [](#donation-widget-is-not-visible) Check: - Static TypoScript template `ALT Text Generator` is included - `licenseKey` is configured - Site URL is resolved correctly - The API returns a donation payload for the subscription - The content element uses one of the fixed bottom layouts License ------- [](#license) Copyright (c) 2026 barrierefrei.space Licensed under GPL-2.0-or-later.
