+After [this deployment](https://github.com/BA-OST-Index/ost_data_site/commit/5c902625e8ff8c04ae38e05ead1d63ead3456c7c) we decided to make the process more integrated. Therefore, we are now archiving this repo and using [the only site generator](https://github.com/BA-OST-Index/ost_site_generator) to generate and publish the site.
+
+Thank you for your continuous support.
