+## Local Installation Configuration
+
+If you've used Claude Code's `migrate-installer` command to move to a local installation, you'll need to configure the plugin to use the local path.
+
+### What is a Local Installation?
+
+Claude Code offers a `claude migrate-installer` command that:
+
+- Moves Claude Code from a global npm installation to `~/.claude/local/`
+- Avoids permission issues with system directories
+- Creates shell aliases but these may not be available to Neovim
+
+### Detecting Your Installation Type
+
+Check your installation type:
+
+```bash
+# Check where claude command points
+which claude
+
+# Global installation shows: /usr/local/bin/claude (or similar)
+# Local installation shows: alias to ~/.claude/local/claude
+
+# Verify installation health
+claude doctor
+```
+
+### Configuring for Local Installation
+
+If you have a local installation, configure the plugin with the direct path:
+
+```lua
+{
+  "coder/claudecode.nvim",
+  dependencies = { "folke/snacks.nvim" },
+  opts = {
+    terminal_cmd = "~/.claude/local/claude", -- Point to local installation
+  },
+  config = true,
+  keys = {
+    -- Your keymaps here
+  },
+}
+```
+
+<details>
+<summary>Native Binary Installation (Alpha)</summary>
+
+Claude Code also offers an experimental native binary installation method currently in alpha testing. This provides a single executable with no Node.js dependencies.
+
+#### Installation Methods
+
+Install the native binary using one of these methods:
+
+```bash
+# Fresh install (recommended)
+curl -fsSL claude.ai/install.sh | bash
+
+# From existing Claude Code installation
+claude install
+```
+
+#### Platform Support
+
+- **macOS**: Full support for Intel and Apple Silicon
+- **Linux**: x64 and arm64 architectures
+- **Windows**: Via WSL (Windows Subsystem for Linux)
+
+#### Benefits
+
+- **Zero Dependencies**: Single executable file with no external requirements
+- **Cross-Platform**: Consistent experience across operating systems
+- **Secure Installation**: Includes checksum verification and automatic cleanup
+
+#### Configuring for Native Binary
+
+The exact binary path depends on your shell integration. To find your installation:
+
+```bash
+# Check where claude command points
+which claude
+
+# Verify installation type and health
+claude doctor
+```
+
+Configure the plugin with the detected path:
+
+```lua
+{
+  "coder/claudecode.nvim",
+  dependencies = { "folke/snacks.nvim" },
+  opts = {
+    terminal_cmd = "/path/to/your/claude", -- Use output from 'which claude'
+  },
+  config = true,
+  keys = {
+    -- Your keymaps here
+  },
+}
+```
+
+</details>
+
+> **Note**: If Claude Code was installed globally via npm, you can use the default configuration without specifying `terminal_cmd`.
