-Moku is a fast, minimal manga reader frontend for [Suwayomi-Server](https://github.com/Suwayomi/Suwayomi-Server). It wraps Suwayomi's GraphQL API in a lightweight Tauri app — no Electron overhead.

-## Features
-
-- **Library management** — organize manga into folders, track unread counts, filter by genre
-- **Per-folder sorting & filtering** — each folder has its own independent sort (unread, A–Z, recently read, latest chapter, and more) and publication status filter (Ongoing, Completed, Hiatus, etc.)
-- **Built-in reader** — single page, long strip, configurable fit modes, customizable keybinds
-- **Markers** — pin color-coded notes to any page while reading; markers appear as dots on the progress bar and are browseable under Series Detail → Manage → Markers
-- **Extension support** — install and manage Suwayomi extensions directly from the app
-- **Download management** — queue and monitor chapter downloads with progress toasts
-- **Automation** — pre-download titles automatically and optionally delete chapters after reading (accessible from Series Detail)
-- **Discord Rich Presence** — shows manga title, current chapter, and elapsed timer in your Discord status; configurable in Settings → General
-- **Auto-start server** — optionally launch Suwayomi in the background on startup
-- **Multiple themes** — Dark, Light, Midnight, Warm, High Contrast, and more
-- **Auto-updates** — in-app update checker with silent background notifications
-- **Improved NSFW filtering** — expanded tag parser gives the Hide NSFW setting better coverage across sources

-![Runs on Windows](https://www.shieldcn.dev/badge/Runs%20on-Windows-0078D4.svg?logo=windows&logoColor=fff)
-![Runs on Linux](https://www.shieldcn.dev/badge/Runs%20on-Linux-FCC624.svg?logo=linux&logoColor=000)
-![Runs on macOS](https://www.shieldcn.dev/badge/Runs%20on-MacOS-000000.svg?mode=light&logo=apple&logoColor=fff)
-
-</div>
-
-### Windows
-
-**winget:**
-
-```powershell
-winget install Moku.Moku
 ```
 
-> Thanks to [@frozenKelp](https://github.com/frozenKelp) for setting up and maintaining the winget package through v0.9.0.
+To recreate this project with the same configuration:
 
-Or download the `.exe` installer from the [releases page](https://github.com/moku-project/Moku/releases/latest). Suwayomi-Server and a JRE are bundled.
+```sh
-
+# recreate this project
-### Linux (Flatpak, recommended)
+pnpm dlx sv@0.15.3 create --template minimal --types ts --install pnpm .
-
-Suwayomi-Server and a bundled JRE are included — no separate install needed.
-
-```bash
-flatpak install io.github.moku_app.Moku
 ```
 
-Or download the latest `moku.flatpak` from the [releases page](https://github.com/moku-project/Moku/releases/latest) and install manually:
+## Developing
 
-```bash
+Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
-flatpak install moku.flatpak
+
+```sh
+npm run dev
+
+# or start the server and open the app in a new browser tab
+npm run dev -- --open
 ```
 
-### Nix
+## Building
 
-```bash
+To create a production version of your app:
-nix run github:moku-project/Moku
+
+```sh
+npm run build
 ```
 
-Add to your flake:
+You can preview the production build with `npm run preview`.
 
-```nix
+> To deploy your app, you may need to install an [adapter](https://svelte.dev/docs/kit/adapters) for your target environment.
-inputs.moku.url = "github:moku-project/Moku";
-```
-
-### macOS
-
-Download the `.dmg` from the [releases page](https://github.com/moku-project/Moku/releases/latest).
-
-> **Note:** Builds are ad-hoc signed. On first launch you may need to run:
-> ```bash
-> xattr -rd com.apple.quarantine /Applications/Moku.app
-> ```
-
----
-
-## Requirements
-
-If you're not using the bundled Flatpak or Windows installer, [Suwayomi-Server](https://github.com/Suwayomi/Suwayomi-Server) must be running separately. By default Moku connects to `http://127.0.0.1:4567`.
-
-You can point Moku at any Suwayomi instance — local or remote — via **Settings → General → Server URL**.
-
----
-
-## Development
-
-**Prerequisites:** [Rust](https://rustup.rs), [Node.js](https://nodejs.org), [pnpm](https://pnpm.io), and [Tauri v2 prerequisites](https://tauri.app/start/prerequisites/).
-
-```bash
-git clone https://github.com/moku-project/Moku
-cd Moku
-pnpm install
-pnpm tauri:dev
-```
-
-Or with Nix:
-
-```bash
-nix develop
-pnpm install
-pnpm tauri:dev
-```
