-# Go Search Engine
+# Ocásek (Warp) Search Engine
 
-A self-hosted [metasearch engine](https://en.wikipedia.org/wiki/Metasearch_engine) that respects privacy, contains no ads, and serves as a proxy/alternative to Google website.
+A self-hosted private and anonymous [metasearch engine](https://en.wikipedia.org/wiki/Metasearch_engine), that aims to be more resource effichent and scalable. Decentralized services are nice, but juming between instances when one just stops working for some reason is just inconvenient. So thats why this engine can do both, you can self-hoste it or use [officiall instance](https://search.spitfirebrowser.com/).
