 # How to Use ZeroLimit
+## Getting Started
 
-ZeroLimit is a Windows desktop application for monitoring AI coding assistant quotas. Track your usage across Antigravity, Anthropic Claude, Codex (OpenAI), and Gemini CLI accounts in one dashboard.
+### 1. Installation
+- Download `ZeroLimit_x.x.x_x64-setup` from Releases
+- Run the installer
+- Launch ZeroLimit from Start Menu
 
-## Prerequisites
+### 2. First Launch - Onboarding
 
-Before using ZeroLimit, you need CLIProxyAPI running either **locally** or on a **remote server**:
+On first launch, you'll be guided through a setup wizard to configure CLIProxyAPI. You can choose between two setup modes:
 
-### Option A: Local Setup
-> [!NOTE]
-> if you want to use kiro & github copilot support, you need to download [CLIProxyAPI Plus Version](https://github.com/router-for-me/CLIProxyAPIPlus/releases)
+---
 
-### Option A: Local Setup
-1. Go to [CLIProxyAPI Releases](https://github.com/router-for-me/CLIProxyAPI/releases)
-2. Download `cli-proxy-api.exe` for Windows
-3. Extract to a folder (e.g., `C:\CLIProxyAPI\`)
+#### Option A: Auto Download (Recommended)
 
-## Getting Started
+The easiest way to get started. ZeroLimit will automatically download and configure the CLI Proxy for you.
 
-### 1. Installation
+1. Click **Get Started** on the welcome screen
+2. Select **Auto Download**
+3. Choose your version:
+   - **Standard** — The original CLI Proxy API
+   - **Plus** — Enhanced version with GitHub Copilot and Kiro support
+4. ZeroLimit will download and extract the correct binary for your OS
+5. Set a **Management Key** — this is the secret key used to protect the management API
+6. Click **Finish Setup** — the proxy starts automatically and you're logged in
 
-**Windows:**
-- Download `ZeroLimit_x.x.x_x64-setup.exe` from Releases
-- Run the installer
-- Launch ZeroLimit from Start Menu
+> [!TIP]
+> The Auto Download mode handles everything: downloading the binary, writing the `config.yaml`, starting the server, and logging you in — all in one flow.
+
+---
 
-### 2. First Launch - Login
+#### Option B: Manual Setup
 
-On first launch, you'll see the login screen with these sections:
+If you already have CLIProxyAPI downloaded or prefer to manage it yourself:
 
-1. **CLI Proxy Server** (Local only)
-   - Click **Change** to browse and select your `cli-proxy-api.exe`
-   - Click **Start** to launch the proxy server
-   - *Skip this if using a remote HTTPS server*
+1. Click **Get Started** on the welcome screen
+2. Select **Manual Location**
+3. Browse and select your `cli-proxy-api.exe` (or `cli-proxy-api-plus.exe`)
+4. Set a **Management Key**
+5. Click **Finish Setup**
 
-2. **API Base URL**
-   - **Local**: `http://localhost:8317`
-   - **Remote HTTPS**: `https://llm.yourdomain.com`
 
-3. **Management Key** (required)
-   - Enter the `secret-key` from your CLIProxyAPI `config.yaml`
-   - This key is required for authentication
 
-4. **Remember credentials**
-   - Check to save your settings for next time
+> [!NOTE]
+> For the Plus version with Kiro & GitHub Copilot support, download from [CLIProxyAPI Plus Releases](https://github.com/router-for-me/CLIProxyAPIPlus/releases).
+> For the Standard version, download from [CLIProxyAPI Releases](https://github.com/router-for-me/CLIProxyAPI/releases).
+
+---
 
-5. Click **Login** to connect to the dashboard
+#### Option C: Remote Server
+
+If you're connecting to a remote HTTPS server, click **Skip For Now** during onboarding and log in manually:
+
+1. Enter your **API Base URL** (e.g., `https://llm.yourdomain.com`)
+2. Enter the **Management Key** from your server's `config.yaml`
