+
+Claude Code is an AI-powered command-line tool that helps you build features, debug code, and navigate codebases directly from your terminal. It provides autonomous coding assistance and integrates with your existing development workflow.
+
+Claude Code works seamlessly on Arm-based systems, including Linux distributions running on Arm servers, macOS on Apple Silicon, and Windows on Arm devices.
+
+## What should I do before installing Claude Code?
+
+You need a Claude account to use Claude Code. A Claude.ai account is recommended, though you can also use a Claude Console account.
+
+If you don't have a Claude account, visit [Claude.ai](https://claude.ai/) and sign up.
+
+Claude Code offers various pricing tiers including free usage for verified users. Visit [Claude pricing](https://www.anthropic.com/pricing) to review the options.
+
+## How do I install Claude Code?
+
+Claude Code is a terminal application that works on macOS, Linux, and Windows systems, including Arm-based platforms.
+
+### Install on Linux (Arm)
+
+The recommended installation method for Linux uses the installation script:
+
+```bash { target="ubuntu:latest" }
+curl -fsSL https://claude.ai/install.sh | bash
+```
+
+This script automatically detects your system architecture and installs the appropriate version for Arm64 systems.
+
+Add Claude Code to your PATH:
+
+```bash
+echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc && source ~/.bashrc
+```
+
+### Install on macOS (Apple Silicon)
+
+On macOS, you can use the installation script:
+
+```bash
+curl -fsSL https://claude.ai/install.sh | bash
+```
+
+Or install using Homebrew:
+
+```bash
+brew install anthropics/claude/claude
+```
+
+### Install on Windows on Arm
+
+On Windows systems, including Windows on Arm, install using npm:
+
+```console
+npm install -g @anthropic-ai/claude
+```
+
+You can also download the Windows installer from the [Claude Code downloads page](https://code.claude.com/docs/en/setup).
+
+### Verify installation
+
+Confirm Claude Code is installed by checking the version:
+
+```console
+claude --version
+```
+
+The output shows the installed version:
+
+```output
+2.0.69 (Claude Code)
+```
+
+## How do I authenticate Claude Code?
+
+After installing Claude Code, you need to authenticate:
+
+1. Navigate to a project directory:
+
+```console
+cd your-project
+```
+
+2. Start Claude Code:
+
+```console
+claude
+```
+
+3. On first use, Claude Code prompts you to log in through your browser
+4. Follow the authentication prompts in your browser
+5. Return to your terminal to continue
+
+Claude Code automatically saves your authentication credentials for future sessions.
+
+## How do I confirm Claude Code is working?
+
+Test Claude Code by asking it to perform a simple task:
+
+1. In your terminal, start Claude Code in a project directory:
+
+```console
+claude
+```
+
+2. Type a request, for example:
+
+```console
+> Create a Python function to calculate fibonacci numbers for my Arm machine
+```
+
+3. Claude Code analyzes your request, creates a plan, and generates the code
+4. Review the proposed changes before accepting them
+
+Claude Code shows you a preview of changes before applying them, giving you control over what gets modified in your codebase.
+
+If Claude Code doesn't respond:
+- Verify you're authenticated (run `claude` and check for authentication prompts)
+- Check your internet connection
+- Ensure your Claude account is active
+- Try restarting Claude Code
+
+
+## How do I use MCP Servers with Claude Code?
+
+Model Context Protocol (MCP) Servers extend Claude Code's capabilities by providing specialized tools and knowledge bases. Claude Code can connect to MCP servers to access domain-specific expertise and functionality.
+
+The Arm MCP Server provides AI assistants with tools and knowledge for Arm architecture development, migration, and optimization. This is particularly useful when working on Arm-based systems.
+
+### What tools does the Arm MCP Server provide?
+
+The Arm MCP Server includes several tools designed for Arm development:
+
+- migrate-ease scan: Analyzes codebases for x86-specific code that needs updating for Arm compatibility
+- skopeo: Inspects container images to check for ARM64 architecture support
+- knowledge_base_search: Searches Arm documentation and learning resources
+- mca (Machine Code Analyzer): Analyzes assembly code for performance on Arm architectures
+- check_image: Verifies Docker image architecture compatibility
+
+### How do I configure the Arm MCP Server with Claude Code?
+
+You need Docker running on your system to use the Arm MCP Server. See the [Docker install guide](/install-guides/docker/) for instructions.
+
+First, pull the Arm MCP Server image:
+
+```console
+docker pull armlimited/arm-mcp:latest
+```
+
+Configure the Arm MCP Server using the `claude mcp add` command. You can configure MCP servers at three different scopes:
+
+- Local scope (default): Available only to you in the current project
+- Project scope: Shared with everyone in the project via `.mcp.json` file
+- User scope: Available to you across all projects
+
+{{% notice Note %}}
+Choose the appropriate scope based on your needs. Project scope is recommended for team collaboration, while user scope is useful for personal tools you use across multiple projects.
+{{% /notice %}}
+
+#### Configure for a specific project (local scope)
+
+Navigate to your project directory and add the Arm MCP Server:
+
+```console
+cd your-project
+claude mcp add --transport stdio arm-mcp -- docker run --rm -i -v "$(pwd):/workspace" armlimited/arm-mcp:latest
+```
+
+This configuration is stored in `~/.claude.json` under your project's path and is only accessible when working in this directory.
+
+#### Configure for all projects (user scope)
+
+To make the Arm MCP Server available across all your projects:
+
+```console
+claude mcp add --scope user --transport stdio arm-mcp -- docker run --rm -i -v "$(pwd):/workspace" armlimited/arm-mcp:latest
+```
+
+This configuration is stored in `~/.claude.json` and is accessible from any project directory.
+
+#### Configure for team sharing (project scope)
+
+To share the MCP server configuration with your team via version control:
+
+```console
+cd your-project
+claude mcp add --scope project --transport stdio arm-mcp -- docker run --rm -i -v "$(pwd):/workspace" armlimited/arm-mcp:latest
+```
+
+This creates a `.mcp.json` file in your project root that can be committed to version control.
+
+### How do I analyze a local codebase with the Arm MCP Server?
+
+The Arm MCP Server automatically mounts your current working directory to the `/workspace` folder inside the Docker container when you use the configuration commands shown above.
+
+To analyze a different directory, modify the volume mount in the `docker run` command. For example, to analyze `/Users/username/myproject`:
+
+```console
+claude mcp add --transport stdio arm-mcp -- docker run --rm -i -v "/Users/username/myproject:/workspace" armlimited/arm-mcp:latest
+```
+
+### How do I verify the Arm MCP Server is working?
+
+List configured MCP servers:
+
+```console
+claude mcp list
+```
+
+You should see `arm-mcp` in the list of configured servers.
+
+Get details about the Arm MCP Server configuration:
+
+```console
+claude mcp get arm-mcp
+```
+
+To test the server's functionality, start Claude Code and ask it to use the Arm MCP tools:
+
+```console
+claude
+```
+
+Then try one of these prompts:
+
+```console
+> Use the Arm MCP Server to scan my codebase for x86-specific code
+```
+
+or
+
+```console
+> Check if the nginx:latest Docker image supports Arm64
+```
+
+You can also use the `/mcp` command within Claude Code to see the status of all connected MCP servers and their available tools.
+
+### Example prompts using the Arm MCP Server
+
+Here are some example prompts that use the Arm MCP Server tools:
+
+- `Scan my workspace for code that needs updating for Arm compatibility`
+- `Check if the postgres:latest container image supports Arm64 architecture`
+- `Search the Arm knowledge base for NEON intrinsics examples`
+- `Find learning resources about migrating from x86 to Arm`
+- `Analyze this assembly code for performance on Arm processors`
+
+### Managing MCP servers
+
+Remove an MCP server:
+
+```console
+claude mcp remove arm-mcp
+```
+
+Update an MCP server configuration by removing and re-adding it with new settings.
+
+Check MCP server status within Claude Code:
+
+```console
+> /mcp
+```
+
+### Troubleshooting MCP Server connections
+
+If the Arm MCP Server doesn't connect:
+
+- Verify Docker is running: `docker ps`
+- Check that the image was pulled successfully: `docker images | grep arm-mcp`
+- Ensure the volume mount path exists and is accessible
+- Check that the Docker daemon is running and accessible
+- Try restarting Claude Code after configuration changes
+- Review the output of `claude mcp get arm-mcp` for configuration errors
