# Documentation Change Analysis for `setup.md`
## Summary
The documentation for installation commands has been streamlined by removing redundant `theme={null}` parameters from code blocks. This change enhances readability and clarity for developers.
## Key Changes
- Removed `theme={null}` from all code block headers for various installation methods (macOS, Linux, Windows PowerShell, Windows CMD, Homebrew, NPM).
- Simplified the appearance of code snippets, making them cleaner and easier to copy.
- Maintained the same installation commands, ensuring functionality remains unchanged.
## Impact
- **Medium**: This change improves the documentation's clarity and usability, which can enhance the developer experience during setup. Clearer documentation can lead to fewer errors and faster onboarding for new users.

```¶
</Tab>¶
¶
<Tab title="NPM">¶
If you have [Node.js 18 or newer installed](https://nodejs.org/en/download/):¶
¶
```sh theme={null} theme={null} theme={null}¶
npm install -g @anthropic-ai/claude-code¶
```¶
</Tab>¶
</Tabs>¶
¶
<Note>¶
Some users may be automatically migrated to an improved installation method.¶
</Note>¶
¶
After the installation process completes, navigate to your project and start Claude Code:¶
¶
```bash theme={null}¶
cd your-awesome-project¶
claude¶
```¶
¶
Claude Code offers the following authentication options:¶
¶
1. **Claude Console**: The default option. Connect through the Claude Console and complete the OAuth process. Requires active billing in the [Anthropic console](https://console.anthropic.com). A "Claude Code" workspace is automatically created for usage tracking and cost management. You can't create API keys for the Claude Code workspace; it's dedicated exclusively for Claude Code usage.¶
2. **Claude App (with Pro or Max plan)**: Subscribe to Claude's [Pro or Max plan](https://claude.com/pricing) for a unified subscription that includes both Claude Code and the web interface. Get more value at the same price point while managing your account in one place. Log in with your Claude.ai account. During launch, choose the option that matches your subscription type.¶
3. **Enterprise platforms**: Configure Claude Code to use [Amazon Bedrock, Google Vertex AI, or Microsoft Foundry](/en/third-party-integrations) for enterprise deployments with your existing cloud infrastructure.¶
¶
<Note>¶
Claude Code securely stores your credentials. See [Credential Management](/en/iam#credential-management) for details.¶
</Note>¶
¶
## Windows setup¶
¶
**Option 1: Claude Code within WSL**¶
¶
* Both WSL 1 and WSL 2 are supported¶
¶
**Option 2: Claude Code on native Windows with Git Bash**¶
¶
* Requires [Git for Windows](https://git-scm.com/downloads/win)¶
* For portable Git installations, specify the path to your `bash.exe`:¶
```powershell theme={null}¶
$env:CLAUDE_CODE_GIT_BASH_PATH="C:\Program Files\Git\bin\bash.exe"¶
```¶
¶
## Alternative installation methods¶
¶
Claude Code offers multiple installation methods to suit different environments.¶
¶
If you encounter any issues during installation, consult the [troubleshooting guide](/en/troubleshooting#linux-permission-issues).¶
¶
<Tip>¶
Run `claude doctor` after installation to check your installation type and version.¶
</Tip>¶
¶
### Native installation options¶
¶
The native installation is the recommended method and offers several benefits:¶
¶
* One self-contained executable¶
* No Node.js dependency¶
* Improved auto-updater stability¶
¶
If you have an existing installation of Claude Code, use `claude install` to migrate to the native binary installation.¶
¶
For advanced installation options with the native installer:¶
¶
**macOS, Linux, WSL:**¶
¶
```bash theme={null}¶
# Install stable version (default)¶
curl -fsSL https://claude.ai/install.sh | bash¶
¶
# Install latest version¶
curl -fsSL https://claude.ai/install.sh | bash -s latest¶
¶
# Install specific version number¶
curl -fsSL https://claude.ai/install.sh | bash -s 1.0.58¶
```¶
¶
<Note>¶
**Alpine Linux and other musl/uClibc-based distributions**: The native build requires `libgcc`, `libstdc++`, and `ripgrep`. For Alpine: `apk add libgcc libstdc++ ripgrep`. Set `USE_BUILTIN_RIPGREP=0`.¶
</Note>¶
¶
**Windows PowerShell:**¶
¶
```powershell theme={null}¶
# Install stable version (default)¶
irm https://claude.ai/install.ps1 | iex¶
¶
# Install latest version¶
& ([scriptblock]::Create((irm https://claude.ai/install.ps1))) latest¶
¶
# Install specific version number¶
& ([scriptblock]::Create((irm https://claude.ai/install.ps1))) 1.0.58¶
```¶
¶
**Windows CMD:**¶
¶
```batch theme={null}¶
REM Install stable version (default)¶
curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmd¶
¶
REM Install latest version¶
curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd latest && del install.cmd¶
¶
REM Install specific version number¶
curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd 1.0.58 && del install.cmd¶
```¶
¶
<Tip>¶
Make sure that you remove any outdated aliases or symlinks before installing.¶
</Tip>¶
¶
**Binary integrity and code signing**¶
¶
* SHA256 checksums for all platforms are published in the release manifests, currently located at `https://storage.googleapis.com/claude-code-dist-86c565f3-f756-42ad-8dfa-d59b1c096819/claude-code-releases/{VERSION}/manifest.json` (example: replace `{VERSION}` with `2.0.30`)¶
* Signed binaries are distributed for the following platforms:¶
* macOS: Signed by "Anthropic PBC" and notarized by Apple¶
* Windows: Signed by "Anthropic, PBC"¶
¶
### NPM installation¶
¶
For environments where NPM is preferred or required:¶
¶
```sh theme={null}¶
npm install -g @anthropic-ai/claude-code¶
```¶
¶
<Warning>¶
Do NOT use `sudo npm install -g` as this can lead to permission issues and security risks.¶
If you encounter permission errors, see [configure Claude Code](/en/troubleshooting#linux-permission-issues) for recommended solutions.¶
</Warning>¶
¶
