+=================================
+Private searx project is finished
+=================================
+
+We are officially finished with the Private searx project. The goal was to
+extend searx capabilities beyond just searching on the Internet. We added
+support for offline engines. These engines do not connect to the Internet,
+they find results locally.
+
+As some of the offline engines run commands on the searx host, we added an
+option to protect any engine by making them private. Private engines can only be
+accessed using a token.
+
+After searx was prepared to run offline queries we added numerous new engines:
+
+1. Command line engine
+2. MySQL
+3. PostgreSQL
+4. SQLite
+5. Redis
+6. MongoDB
+
+We also added new engines that communicate over HTTP, but you might want to keep
+them private:
+
+1. Elasticsearch
+2. Meilisearch
+3. Solr
+
+The last step was to document this work. We added new tutorials on creating
+command engines, making engines private and also adding a custom result template
+to your own engines.
+
+Acknowledgement
+===============
+
+The project was sponsored by `Search and Discovery Fund`_ of `NLnet
+Foundation`_. We would like to thank the NLnet for not only the funds, but the
+conversations and their ideas. They were truly invested and passionate about
+supporting searx.
