-# Modern CalDAV Web Client
+# Runway
+## _Passive infrastructure for life's coordination_
+
+![Runway Screenshot](sample.png)
 
 >[!WARNING]
 >This project was entirely vibe coded. It's my first attempt vibe coding anything, but I just sat down one day and realized this was something I've wanted to build for many years, but would just take way too long. With AI, I've been able to lay out the majority  of the app in one long weekend. So proceed at your own risk, but I actually think the app is pretty solid.
 
-A full-stack calendar application built with Rust, featuring a modern web interface for CalDAV calendar management.
+A modern CalDAV web client built with Rust WebAssembly.
 
-## Motivation
+## The Name
 
-While there are many excellent self-hosted CalDAV server implementations (Nextcloud, Radicale, Baikal, etc.), the web client ecosystem remains limited. Existing solutions like [AgenDAV](https://github.com/agendav/agendav) often suffer from outdated interfaces, bugs, and poor user experience. This project aims to provide a modern, fast, and reliable web interface for CalDAV servers.
+Runway embodies the concept of **passive infrastructure** — unobtrusive systems that enable better coordination without getting in the way. Planes can fly and do lots of cool things, but without runways, they can't take off or land. Similarly, calendars and scheduling tools are essential for organizing our lives, but they should not dominate our attention.
+
+The best infrastructure is invisible when working, essential when needed, and enables rather than constrains.
