 **Git-native dotfiles management that doesn't suck.**
 
-Move your dotfiles to `~/.config/lnk`, symlink them back, and use Git like normal. Supports both common configurations and host-specific setups.
+Lnk makes managing your dotfiles straightforward, no tedious setups, no complex configurations. Just tell Lnk what files you want tracked, and it'll automatically move them into a tidy Git repository under `~/.config/lnk`. It then creates clean, portable symlinks back to their original locations. Easy.
+
+Why bother with Lnk instead of plain old Git or other dotfile managers? Unlike traditional methods, Lnk automates the boring parts: safely relocating files, handling host-specific setups, bulk operations for multiple files, recursive directory processing, and even running your custom bootstrap scripts automatically. This means fewer manual steps and less chance of accidentally overwriting something important.
+
+With Lnk, your dotfiles setup stays organized and effortlessly portable, letting you spend more time doing real work, not wrestling with configuration files.
 
 ```bash
-lnk init
+lnk init -r git@github.com:user/dotfiles.git    # Clones & runs bootstrap automatically

 Your files live in `~/.config/lnk` (a Git repo). Common files go in the root, host-specific files go in `<host>.lnk/` subdirectories. Lnk creates symlinks back to original locations. Edit files normally, use Git normally.
 
+## Safety Features
+
+Lnk includes built-in safety checks to prevent accidental data loss:
+
+### Data Loss Prevention
+
+```bash
+# This will be blocked if you already have managed files
+lnk init -r git@github.com:user/dotfiles.git
+# ❌ Directory ~/.config/lnk already contains managed files
+#    💡 Use 'lnk pull' to update from remote instead of 'lnk init -r'
+
+# Use pull instead to safely update
+lnk pull
+
+# Or force if you understand the risks (shows warning only when needed)
+lnk init -r git@github.com:user/dotfiles.git --force
+# ⚠️  Using --force flag: This will overwrite existing managed files
+#    💡 Only use this if you understand the risks
+```
+
+### Smart Warnings
+
+- **Contextual alerts**: Warnings only appear when there are actually managed files to overwrite
+- **Clear guidance**: Error messages suggest the correct command to use
+- **Force override**: Advanced users can bypass safety checks when needed
+
+## Bootstrap Support
+
+Lnk automatically runs bootstrap scripts when cloning dotfiles repositories, making it easy to set up your development environment. Just add a `bootstrap.sh` file to your dotfiles repo.
+
+### Examples
+
+**Simple bootstrap script:**
+
+```bash
+#!/bin/bash
+# bootstrap.sh
+echo "Setting up development environment..."
+
+# Install Homebrew (macOS)
+if ! command -v brew &> /dev/null; then
+    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+fi
+
+# Install packages
+brew install git vim tmux
+
+echo "✅ Setup complete!"
+```
+
+**Usage:**
+
+```bash
+# Automatic bootstrap on clone
+lnk init -r git@github.com:you/dotfiles.git
+# → Clones repo and runs bootstrap script automatically
+
+# Skip bootstrap if needed
+lnk init -r git@github.com:you/dotfiles.git --no-bootstrap
+
+# Run bootstrap manually later
+lnk bootstrap
+```
