## Installation Steps

### 1. Clone the Repository

```

## Verify Installation

```bash
# Check version
passage version

# View help
passage help

# View manpage (if installed)
man passage
```

## Troubleshooting

### Build Fails

1. **Check Go version:**
   ```bash
   go version  # Should be 1.21 or later
   ```

2. **Verify dependencies:**
   ```bash
   go mod verify
   go mod tidy
   ```

3. **Clean and rebuild:**
   ```bash
   make clean
   make build
   ```

### Manpage Won't Build

Install `pandoc`:
- Debian/Ubuntu: `sudo apt-get install pandoc`
- macOS: `brew install pandoc`

Or use `go-md2man`:
```bash
go install github.com/cpuguy83/go-md2man/v2@latest
```

### Clipboard Doesn't Work

Ensure you have clipboard tools installed:
- X11: `xclip` or `xsel`
- Wayland: `wl-clipboard`

Install:
- Debian/Ubuntu: `sudo apt-get install xclip` or `sudo apt-get install wl-clipboard`
- Arch: `sudo pacman -S xclip` or `sudo pacman -S wl-clipboard`
- Other distributions: Install `xclip` or `wl-clipboard` from your package manager
