+# MyCoder Installation Guide for macOS and Linux
+
+This guide provides detailed instructions for installing MyCoder on macOS and Linux operating systems. We'll cover how to install Node.js using NVM (Node Version Manager) and then install the MyCoder CLI.
+
+## Prerequisites
+
+Before installing MyCoder, make sure your system meets the following requirements:
+
+- macOS 10.15+ or Linux (Ubuntu, Debian, CentOS, Fedora, etc.)
+- Terminal access
+- Internet connection
+- Basic command-line knowledge
+
+## Installing Node.js with NVM (Recommended)
+
+Using NVM (Node Version Manager) is the recommended way to install Node.js as it allows you to easily switch between different Node.js versions.
+
+### 1. Install NVM
+
+#### macOS and Linux
+
+Open your terminal and run the following command:
+
+```bash
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
+```
+
+Or using wget:
+
+```bash
+wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
+```
+
+After installation, you'll need to close and reopen your terminal, or run the following to use NVM right away:
+
+```bash
+export NVM_DIR="$HOME/.nvm"
+[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
+[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
+```
+
+To verify that NVM is installed, run:
+
+```bash
+nvm --version
+```
+
+### 2. Install Node.js
+
+MyCoder requires Node.js version 20.0.0 or later. Install it using NVM:
+
+```bash
+nvm install 20
+nvm use 20
+```
+
+To verify the installation, run:
+
+```bash
+node --version
+```
+
+This should display a version number that starts with `v20.x.x`.
+
+## Alternative: Direct Node.js Installation
+
+If you prefer not to use NVM, you can install Node.js directly.
+
+### macOS
+
+1. Using Homebrew (recommended for macOS):
+
+```bash
+# Install Homebrew if you don't have it
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+
+# Install Node.js
+brew install node
+```
+
+2. Using the official installer:
+   - Download the macOS installer from [Node.js official website](https://nodejs.org/)
+   - Run the installer and follow the instructions
+
+### Linux
+
+#### Ubuntu/Debian:
+
+```bash
+# Add NodeSource repository
+curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
+
+# Install Node.js
+sudo apt-get install -y nodejs
+```
+
+#### CentOS/RHEL/Fedora:
+
+```bash
+# Add NodeSource repository
+curl -fsSL https://rpm.nodesource.com/setup_20.x | sudo bash -
+
+# Install Node.js
+sudo yum install -y nodejs
+```
+
+#### Arch Linux:
+
+```bash
+sudo pacman -S nodejs npm
+```
+
+## Installing MyCoder
+
+Once Node.js is installed, you can install MyCoder globally using npm:
+
+```bash
+npm install -g mycoder
+```
+
+To verify the installation, run:
+
+```bash
+mycoder --version
+```
+
+This should display the current version of MyCoder.
+
+## Setting Up API Keys
+
+MyCoder requires an API key from your chosen AI provider. You can set this up using environment variables:
+
+```bash
+# For Anthropic (recommended)
+export ANTHROPIC_API_KEY=your-api-key
+
+# Or for OpenAI
+export OPENAI_API_KEY=your-api-key
+
+# Or for Mistral AI
+export MISTRAL_API_KEY=your-api-key
+
+# Or for xAI/Grok
+export XAI_API_KEY=your-api-key
+```
+
+To make these environment variables persistent, add them to your shell profile file:
+
+### For Bash (macOS and Linux)
+
+```bash
+echo 'export ANTHROPIC_API_KEY=your-api-key' >> ~/.bashrc
+source ~/.bashrc
+```
+
+### For Zsh (default on macOS)
+
+```bash
+echo 'export ANTHROPIC_API_KEY=your-api-key' >> ~/.zshrc
+source ~/.zshrc
+```
+
+Alternatively, you can create a `.env` file in your working directory with the appropriate key:
+
+```
+ANTHROPIC_API_KEY=your-api-key
+```
+
+## GitHub Integration (Optional)
+
+If you plan to use MyCoder's GitHub integration, you'll need to install the GitHub CLI (`gh`):
+
+### macOS
+
+```bash
+brew install gh
+```
+
+### Linux
+
+#### Ubuntu/Debian:
+
+```bash
+# Add the GitHub CLI repository
+type -p curl >/dev/null || (sudo apt update && sudo apt install curl -y)
+curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | sudo dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg \
+&& sudo chmod go+r /usr/share/keyrings/githubcli-archive-keyring.gpg \
+&& echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" | sudo tee /etc/apt/sources.list.d/github-cli.list > /dev/null \
+&& sudo apt update \
+&& sudo apt install gh -y
+```
+
+#### Fedora/CentOS/RHEL:
+
+```bash
+sudo dnf install gh
+```
+
+#### Arch Linux:
+
+```bash
+sudo pacman -S github-cli
+```
+
+After installation, authenticate with GitHub:
+
+```bash
+gh auth login
+```
+
+Follow the interactive prompts to complete the authentication process.
+
+## Basic Usage
+
+Once installed, you can start using MyCoder:
+
+```bash
+# Interactive mode
+mycoder -i
+
+# Run with a prompt
+mycoder "Implement a React component that displays a list of items"
+
+# Enable GitHub mode
+mycoder config set githubMode true
+```
+
+For more detailed usage instructions, see the [MyCoder Usage Guide](usage.md).
+
+## Troubleshooting
+
+### Common Issues on macOS
+
+1. **Permission Errors**: If you encounter permission errors when installing packages globally:
+
+```bash
+sudo npm install -g mycoder
+```
+
+2. **Command Not Found**: If the `mycoder` command is not found after installation, check your PATH:
+
+```bash
+echo $PATH
+```
+
+Ensure that the npm global bin directory is in your PATH. You can add it with:
+
+```bash
+echo 'export PATH="$PATH:$(npm config get prefix)/bin"' >> ~/.zshrc
+source ~/.zshrc
+```
+
+### Common Issues on Linux
+
+1. **Missing Dependencies**: If you encounter missing dependencies:
+
+```bash
+# For Ubuntu/Debian
+sudo apt-get install -y build-essential
+
+# For CentOS/RHEL/Fedora
+sudo yum group install "Development Tools"
+```
+
+2. **Node.js Version Conflicts**: If you have multiple Node.js versions installed:
+
+```bash
+# Use NVM to switch to the correct version
+nvm use 20
+```
