 This is a cutting-edge **file and document server** designed for speed, efficiency, and unparalleled ease of use. Experience **lightning-fast browsing**, thanks to the file list maintained directly in your browser and updated from server filesystem events, coupled with our highly optimized code. Fully **keyboard-navigable** and with a responsive layout, Cista flawlessly adapts to your devices, providing a seamless experience wherever you are. Our powerful **instant search** means you're always just a few keystrokes away from finding exactly what you need. Press **1/2/3** to switch ordering, navigate with all four arrow keys (+Shift to select). Or click your way around on **breadcrumbs that remember where you were**.
 
+**Built-in document and media previews** let you quickly view files without downloading them. Cista shows PDF and other documents, video and image thumbnails, with **HDR10 support** video previews and image formats, including HEIC and AVIF. It also has a player for music and video files.
+
 The Cista project started as an inevitable remake of [Droppy](https://github.com/droppyjs/droppy) which we used and loved despite its numerous bugs. Cista Storage stands out in handling even the most exotic filenames, ensuring a smooth experience where others falter.
 
 All of this is wrapped in an intuitive interface with automatic light and dark themes, making Cista Storage the ideal choice for anyone seeking a reliable, versatile, and quick file storage solution. Quickly setup your own Cista where your files are just a click away, safe, and always accessible.

 ## Getting Started
-### Installation
-
-To install the cista application, use:
-
-```fish
-pip install cista
-```
-
-Note: Some Linux distributions might need `--break-system-packages` to install Python packages, which are safely installed in the user's home folder. As an alternative to avoid installation, run it with command `pipx run cista`
-
 ### Running the Server
 
-Create an account: (or run a public server without authentication)
+We recommend using [UV](https://docs.astral.sh/uv/getting-started/installation/) to directly run Cista:
+
+Create an account: (otherwise the server is public for all)
 ```fish
-cista --user yourname --privileged
+uvx cista --user yourname --privileged
 ```
 
 Serve your files at http://localhost:8000:
 ```fish
-cista -l :8000 /path/to/files
+uvx cista -l :8000 /path/to/files
+```
+
+Alternatively, you can install with `pip` or `uv pip`. This enables using the `cista` command directly without `uvx` or `uv run`.
+
+```fish
+pip install cista --break-system-packages
 ```
 
 The server remembers its settings in the config folder (default `~/.local/share/cista/`), including the listen port and directory, for future runs without arguments.
 
 ### Internet Access
 
-To use your own TLS certificates, place them in the config folder and run:
+Most admins find the [Caddy](https://caddyserver.com/) web server convenient for its auto TLS certificates and all. A proxy also allows running multiple web services or Cista instances on the same IP address but different (sub)domains.

-For rapid development, we use the Vite development server for the Vue frontend, while running the backend on port 8000 that Vite proxies backend requests to. Each server live reloads whenever its code or configuration are modified.
-
-```fish
-cd frontend

-Concurrently, start the backend on another terminal:

-```fish
-hatch shell
-pip install -e '.[dev]'
-cista --dev -l :8000 /path/to/files

-We use `hatch shell` for installing on a virtual environment, to avoid disturbing the rest of the system with our hacking.
