It will be an overview of open-source Integrated Library System software called, koha.  This is a very flexible software that can be customized with JQuery, Bootstrap 5, JavaScript, and CSS.  It has an active international community to help with all questions, bugs, and version updates.  I work on koha ILS for McKinney Public Library, we love it.  The migration of more libraries or special institutions moving away from large scale ILS software/providers to koha has increased.  More information on koha:
