-# Overview
+# homedir
 
-These are for common files in my home directory.
+My macOS dotfiles. Simple, symlink-based configuration for a productive development environment.
 
 ## Install
 
 ```bash
-    cd ~
-    git clone https://github.com/TechNickAI/homedir.git
-    cd homedir
+cd ~
+git clone https://github.com/TechNickAI/homedir.git
+cd homedir
+git submodule init
+git submodule update
+bash setup.sh
+```
+
+Or as a one-liner:
+
+```bash
+curl "https://raw.githubusercontent.com/TechNickAI/homedir/master/install.sh" | bash
+```
+
+After installing, run the macOS defaults script:
+
+```bash
+~/.macos
+```
+
+## What's Included
+
+### Shell Configuration
+
+- **`.my_mac_zshrc`** - macOS-specific zsh config with Homebrew, virtualenv aliases, and utilities
+- **`.my_zshrc`** - Cross-platform zsh base config
+- **`.zshenv`** - Universal environment setup (virtualenvwrapper, Python paths)
+- **`.profile`** - Bash config with history management and git aliases
+- **`.bash_prompt`** - Colorized prompt with git status
+
+### Vim
+
+- **`.vimrc`** - Vim configuration with Pathogen plugin manager
+- Plugins: Syntastic, CtrlP, indent guides, rainbow parentheses
+- 160-char line width with visual guide
+
+### Git
+
+- **`.gitconfig`** - Safe defaults: `pull.ff=only`, rebase on pull, autocorrect
+- **`.gitignore`** - Global ignore patterns
+
+### Code Quality
+
+- **`.pre-commit-config.yaml`** - Pre-commit hooks with Ruff for Python
+- **`.prettierrc`** - Prettier config (88-char width, consistent with Python)
+- **`.jshintrc`** - JavaScript linting
+
+### Command-Line Tools (via Brewfile)
+
+```bash
+brew bundle --file=~/homedir/Brewfile
+```
+
+| Tool | Purpose |
+|------|---------|
+| `bat` | Better `cat` with syntax highlighting |
+| `btop` | Modern process viewer |
+| `delta` | Beautiful git diffs |
+| `fzf` | Fuzzy finder for everything |
+| `ag` | Fast code search (silver searcher) |
+| `ncdu` | Disk usage analyzer |
+
+### macOS Defaults (`.macos`)
+
+Run `~/.macos` to configure:
+
+- Screenshots saved to `~/Desktop/ScreenShots/`
+- Key repeat enabled for VS Code (vim j/k navigation)
+- Key repeat enabled for Cursor (vim j/k navigation)
+
+### Automation
+
+**Daily Updates** (`daily_update_mac.sh`)
+
+Scheduled via cron to run at 10am:
+- Updates Homebrew packages
+- Updates npm/pnpm globals
+- Skips when on battery
+
+```bash
+# Add to crontab
+0 10 * * * $HOME/homedir/daily_update_mac.sh >> $HOME/daily_update.log 2>&1
+```
+
+**Environment Loading**
+
+Automatically sources `.env` files from:
+- `~/dot_env_shared` (team-shared)
+- `~/dot_env_local` (local secrets)
+- `~/env`, `~/src/env`, `~/.env`
+
+Use `browse_env_vars` to see loaded variables.
+
+### Smart Git Functions
+
+**`commit_link`** - Copy GitHub URL of latest commit to clipboard
+
+**`_smart_git_update`** - Intelligent branch management:
+- Detects uncommitted changes (stays on branch)
+- Checks for unpushed commits (warns before switching)
+- Auto-switches to main if current branch is merged
+
+**`clone-carmenta [name]`** / **`clone-cryptoai [name]`** - Clone project with environment setup
+
+## Customization
+
+### Local Overrides
+
+Create `~/.zshrc.local` for machine-specific settings. This file is gitignored and sourced at the end of `.my_mac_zshrc`:
+
+```bash
+# ~/.zshrc.local example
+export WORK_API_KEY="secret"
+alias deploy="./scripts/deploy-prod.sh"
+```
+
+### Adding macOS Defaults
 
-    # Update the submodules (vim plugins)
-    git submodule init
-    git submodule update
+Edit `.macos` to add your preferred system settings. Check [mathiasbynens/dotfiles](https://github.com/mathiasbynens/dotfiles/blob/main/.macos) for inspiration.
