-# Welcome to Loco :train:
+# Tenis Rajec — tenisrajec.sk
 
-[Loco](https://loco.rs) is a web and API framework running on Rust.
+Booking site for the tennis courts in Rajec. Visitors browse the weekly court
+calendar and an *About* page; the single admin manages courts, bookings and the
+About-page content.
 
-This is the **SaaS starter** which includes a `User` model and authentication based on JWT.
-It also include configuration sections that help you pick either a frontend or a server-side template set up for your fullstack server.
+Built with [Loco](https://loco.rs), a web framework running on Rust.
