-- Copy all the files from the folder repository in this directory.
-- In the method ns.LibrarySelector.prototype.appendTo (scripts/h5peditor-library-selector.js),
-  comment the line "this.$selector.appendTo($element);" to avoid the display of the Hub Selector.

-unexisting ones. Remember to use the AMOS script commands, such CPY, to copy
-all the existing strings from the previous version. As you'll see, all the
-strings in en.js have been converted following these rules:
-  * Prefix  "editor:" has been added.
-  * Keys have been lowercased.
-- Add namespace to this library to avoid collision. It means:
-  * Add the "namespace Moodle;" line at the top of all the h5peditor*.php files in the root folder.
-  * Replace \H5Pxxx uses to H5Pxxx (for instance, in h5peditor-ajax.class.php there are several references to \H5PCore that
-must be replaced with H5PCore).
-  * Add "use stdClass;" in h5peditor.class.php and h5peditor-file.class.php (check that it's still used before replacing it when upgrading the library).

+ * Remove the content in this folder (but the readme_moodle.txt)
+ * Copy all the files from the folder repository in this directory.
 
 Removed:
  * composer.json
  * .gitignore
 
-Added:
- * readme_moodle.txt

 Changed:
- * Updated H5peditor::getLibraryData parameters to fix PHP8.0 warnings. See MDL-70903 for details.
- * Make get_magic_quotes_gpc() use conditional, it has been removed in php80. See MDL-73502 for details.
- * Updated CKEditor to 4.17.1 from https://github.com/h5p/h5p-editor-php-library/commit/1ae19fdb80839b32dad3846d6b0a5c745f8f6187. It has been applied the commit on h5p-editor-php-library where CKEditor is updated to 4.17.1. Once, this library will be upgraded to the latest version, this changed should be removed.
