-# Web File Storage
-
-Run directly from repository with Hatch (or use pip install as usual):
-```sh
-hatch run cista -l :3000 /path/to/files
-```
-
-Settings incl. these arguments are stored to config file on the first startup and later `hatch run cista` is sufficient. If the `cista` script is missing, consider `pip install -e .` (within `hatch shell`) or some other trickery (known issue with installs made prior to adding the startup script).
-
-Create your user account:
-```sh
-hatch run cista --user admin --privileged
-```
-
-## Build frontend
-
-Prebuilt frontend is provided in repository but for any changes it will need to be manually rebuilt:
-
-```sh
-cd cista-front
-npm install
-npm run build
-```
-
-This will place the front in `cista/wwwroot` from where the backend server delivers it, and that also gets included in the Python package built via `hatch build`.
+# Cista Web Storage
+
+<img src="https://git.zi.fi/Vasanko/cista-storage/raw/branch/main/docs/cista.webp" align=left width=250>
+
+Cista takes its name from the ancient *cistae*, metal containers used by Greeks and Egyptians to safeguard valuable items. This modern application provides a browser interface for secure and accessible file storage, echoing the trust and reliability of its historical namesake.
+
+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**.
+
+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.
+
+Experience Cista by visiting [Cista Demo](https://drop.zi.fi) for a test run and perhaps upload something...
+
+
+## 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)
+```fish
+cista --user yourname --privileged
+```
+
+Serve your files at http://localhost:8000:
+```fish
+cista -l :8000 /path/to/files
+```
+
+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:
+
+```fish
+cista -l cista.example.com
+```
+
+Most admins instead 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.
+
+`/etc/caddy/Caddyfile`:
+
+```Caddyfile
+cista.example.com {
+    reverse_proxy :8000
+}
+```
+
+## Development setup
+
+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
+npm install
+npm run dev
+```
+
+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.
+
+Vue is used to build files in `cista/wwwroot`, included prebuilt in the Python package. Running `hatch build` builds the frontend and creates a NodeJS-independent Python package.
+
+## System Deployment
+
+This setup allows easy addition of storages, each with its own domain, configuration, and files.
+
+Assuming a restricted user account `storage` for serving files and that cista is installed system-wide or on this account (check with `sudo -u storage -s`). Alternatively, use `pipx run cista` or `hatch run cista` as the ExecStart command.
+
+Create `/etc/systemd/system/cista@.service`:
+
+```ini
+[Unit]
+Description=Cista storage %i
+
+[Service]
+User=storage
+ExecStart=cista -c /srv/cista/%i -l /srv/cista/%i/socket /media/storage/%i
+Restart=always
+
+[Install]
+WantedBy=multi-user.target
+```
+
+This setup supports multiple storages, each under `/media/storage/<domain>` for files and `/srv/cista/<domain>/` for configuration. UNIX sockets are used instead of numeric ports for convenience.
+
+```fish
+systemctl daemon-reload
+systemctl enable --now cista@foo.example.com
+systemctl enable --now cista@bar.example.com
+```
+
+Public exposure is easiest using the Caddy web server.
+
+`/etc/caddy/Caddyfile`:
+
+```Caddyfile
+foo.example.com, bar.example.com {
+    reverse_proxy unix//srv/cista/{host}/socket
+}
+```

-
-1. Disable the built-in TypeScript Extension
-    1) Run `Extensions: Show Built-in Extensions` from VSCode's command palette
-    2) Find `TypeScript and JavaScript Language Features`, right click and select `Disable (Workspace)`
-2. Reload the VSCode window by running `Developer: Reload Window` from the command palette.

+# Cista Vue Frontend
+
+The frontend is a Single-Page App implemented with Vue 3. Development uses the Vite server together with the main Python backend, but in production the latter also serves the prebuilt frontend files.
+
+## Recommended IDE Setup
+
+[VSCode](https://code.visualstudio.com/) + [Volar](https://marketplace.visualstudio.com/items?itemName=Vue.volar) (and disable Vetur) + [TypeScript Vue Plugin (Volar)](https://marketplace.visualstudio.com/items?itemName=Vue.vscode-typescript-vue-plugin).
+
+## Type Support for `.vue` Imports in TS
+
+TypeScript cannot handle type information for `.vue` imports by default, so we replace the `tsc` CLI with `vue-tsc` for type checking. In editors, we need [TypeScript Vue Plugin (Volar)](https://marketplace.visualstudio.com/items?itemName=Vue.vscode-typescript-vue-plugin) to make the TypeScript language service aware of `.vue` types.
+
+If the standalone TypeScript plugin doesn't feel fast enough to you, Volar has also implemented a [Take Over Mode](https://github.com/johnsoncodehk/volar/discussions/471#discussioncomment-1361669) that is more performant. You can enable it by the following steps:
+
+1. Disable the built-in TypeScript Extension
+    1) Run `Extensions: Show Built-in Extensions` from VSCode's command palette
+    2) Find `TypeScript and JavaScript Language Features`, right click and select `Disable (Workspace)`
+2. Reload the VSCode window by running `Developer: Reload Window` from the command palette.
+
+## Hot-Reload for Development
+
+### Run the backend
+
+```fish
+hatch shell
+cista --dev -l :8000
+```
+
+### And the Vite server (in another terminal)
+
+```fish
+cd frontend
+npm install
+npm run dev
+```
+Browse to Vite, which will proxy API requests to port 8000. Both servers live reload changes.
+
+
+### Type-Check, Compile and Minify for Production
+
+This is also called by `hatch build` during Python packaging:
+
+```fish
+npm run build
+```
