# OpenClaude Quick Start for Windows

This guide uses Windows PowerShell.

## 1. Install Node.js

Install Node.js 20 or newer from:

- `https://nodejs.org/`

Then open PowerShell and check it:

```powershell
node --version
npm --version
```

## 2. Install OpenClaude

```powershell
npm install -g @gitlawb/openclaude
```

## 3. Pick One Provider

### Option A: OpenAI

Replace `sk-your-key-here` with your real key.

```powershell
$env:CLAUDE_CODE_USE_OPENAI="1"
$env:OPENAI_API_KEY="sk-your-key-here"
$env:OPENAI_MODEL="gpt-4o"

openclaude
```

### Option B: DeepSeek

```powershell
$env:CLAUDE_CODE_USE_OPENAI="1"
$env:OPENAI_API_KEY="sk-your-key-here"
$env:OPENAI_BASE_URL="https://api.deepseek.com/v1"
$env:OPENAI_MODEL="deepseek-v4-flash"

openclaude
```

Use `deepseek-v4-pro` when you want the stronger model. `deepseek-chat` and `deepseek-reasoner` still work as DeepSeek's legacy API aliases.

### Option C: Ollama

Install Ollama first from:

- `https://ollama.com/download/windows`

Then run:

```powershell
ollama pull llama3.1:8b

$env:CLAUDE_CODE_USE_OPENAI="1"
$env:OPENAI_BASE_URL="http://localhost:11434/v1"
$env:OPENAI_MODEL="llama3.1:8b"

openclaude
```

No API key is needed for Ollama local models.

### Option D: LM Studio

Install LM Studio first from:

- `https://lmstudio.ai/`

Then in LM Studio:

1. Download a model (e.g., Llama 3.1 8B, Mistral 7B)
2. Go to the "Developer" tab
3. Select your model and enable the server via the toggle

Then run:

```powershell
$env:CLAUDE_CODE_USE_OPENAI="1"
$env:OPENAI_BASE_URL="http://localhost:1234/v1"
$env:OPENAI_MODEL="your-model-name"
# $env:OPENAI_API_KEY="lmstudio"  # optional: some users need a dummy key

openclaude
```

Replace `your-model-name` with the model name shown in LM Studio.

No API key is needed for LM Studio local models (but uncomment the `OPENAI_API_KEY` line if you hit auth errors).

## 4. If `openclaude` Is Not Found

Close PowerShell, open a new one, and try again:

```powershell
openclaude
```

## 5. If Your Provider Fails

Check the basics:

### For OpenAI or DeepSeek

- make sure the key is real
- make sure you copied it fully

### For Ollama

- make sure Ollama is installed
- make sure Ollama is running
- make sure the model was pulled successfully

### For LM Studio

- make sure LM Studio is installed
- make sure LM Studio is running
- make sure the server is enabled (toggle on in the "Developer" tab)
- make sure a model is loaded in LM Studio
- make sure the model name matches what you set in `OPENAI_MODEL`

## 6. Updating OpenClaude

```powershell
npm install -g @gitlawb/openclaude@latest
```

## 7. Uninstalling OpenClaude

```powershell
npm uninstall -g @gitlawb/openclaude
```
