+## Creating a project
 
-## Features
+If you're seeing this, you've probably already done this step. Congrats!
 
-### Reader
+```sh
-- **Single**, **double-page**, and **longstrip** reading modes
+# create a new project
-- **Infinite longstrip** — when Auto mode is enabled, the next chapter's pages are appended directly into the scroll without any re-render or gap; the entire series flows as one seamless ribbon
+npx sv create my-app
-- Fit modes: fit width, fit height, fit screen, and 1:1 original
-- Per-series zoom control via Ctrl+scroll or a slider popover
-- RTL / LTR reading direction toggle
-- Configurable page gaps
-- Full keyboard navigation with rebindable keybinds
-- UI auto-hides after 3 seconds of inactivity; reappears on cursor movement near edges
-- Chapter-relative page counter that updates live as you scroll through the infinite strip
-- Auto-mark chapters as read when the last page is reached
-
-### Library
-- Grid view of your entire manga collection with lazy-loaded cover art
-- Filter tabs: **Saved**, **Downloaded**, and **All**
-- Genre tag filter chips — multi-select to narrow by any combination of tags
-- In-line search
-- Context menu: open, add/remove from library
-
-### Series Detail
-- Cover, author, artist, status badge, genres, and synopsis
-- Read progress bar with percentage
-- Continue / Start / Re-read button that picks up exactly where you left off (including mid-chapter page)
-- Chapter list with scanlator, upload date, and in-progress page indicator
-- **Grid view** — displays all chapters as numbered tiles; read/unread/in-progress states are visually distinct at a glance; switches between list and grid with a single click
-- Sort by newest or oldest first
-- Jump-to-chapter input
-- Bulk download menu: from current chapter, unread only, or all
-- Per-chapter context menu: mark read/unread, mark all above as read, download, delete, bulk download from here
-- Collapsible source details panel with source ID, language, and source migration
-
-### Search
-- Cross-source search running up to 3 concurrent requests
-- Language filter bar (preferred language default, per-language, or all)
-- Results grouped by source with skeleton loading states
-
-### Sources & Extensions
-- Browse and search installed sources, grouped by extension with per-language expansion
-- Extension manager: install, update, remove, and install from external APK URL
-- Repo refresh with update count badge
-
-### Downloads
-- Download queue with live progress
-
-### History
-- Reading history grouped by day with relative timestamps
-- Per-entry thumbnail, chapter name, and last-read page
-- Full-text search across titles and chapter names
-- One-click clear

-## Requirements
-
-[Suwayomi-Server](https://github.com/Suwayomi/Suwayomi-Server) must be running. By default Moku expects it at `http://127.0.0.1:4567`.
-
-> Moku will attempt to launch the server automatically on startup if the `suwayomi-server` binary is on your `PATH`.
-
----
-
-## Installation
-
-**Nix (recommended)**
-
-```bash
-nix run github:Youwes09/moku
 ```
 
-Add to your flake:
+To recreate this project with the same configuration:
 
-```nix
+```sh
-inputs.moku.url = "github:Youwes09/moku";
+# recreate this project
+pnpm dlx sv@0.15.3 create --template minimal --types ts --install pnpm .
 ```
 
-**From source**
+## Developing
 
-```bash
+Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
-git clone https://github.com/Youwes09/moku
+
-cd moku
+```sh
-nix build
+npm run dev
-./result/bin/moku
+
+# or start the server and open the app in a new browser tab
+npm run dev -- --open
 ```
 
----
+## Building
 
-## Development
+To create a production version of your app:
 
-```bash
+```sh
-nix develop
+npm run build
-pnpm install
-pnpm tauri:dev
 ```
 
-> `tauri:dev` uses `src-tauri/tauri.dev.conf.json` to point at the Vite dev server, keeping the release build config clean for `nix build`.
+You can preview the production build with `npm run preview`.
 
----
+> To deploy your app, you may need to install an [adapter](https://svelte.dev/docs/kit/adapters) for your target environment.
