+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Overview
+
+This is **Campus Code Dotfiles (cc_dotfiles)** — a shared dotfiles distribution for zsh, vim, tmux, and git, targeting macOS and Ubuntu.
+
+## Installation
+
+```bash
+# Remote install (clones to ~/.cc_dotfiles, then runs rake install)
+bash -c "$(curl -fSs https://raw.githubusercontent.com/campuscode/cc_dotfiles/master/install.sh)"
+
+# Local install (from a cloned repo)
+LOCAL_INSTALL=1 bash install.sh
+```
+
+The `install.sh` installs system dependencies, sets up mise (Ruby/Node.js), then copies the repo to `~/.cc_dotfiles` and runs `rake install`. The Rake task symlinks config files into `~/` (prefixed with `.`), installs fonts, vim-plug plugins, zsh-syntax-highlighting, tmux-battery plugin, and changes the default shell to zsh.
+
+## Testing
+
+Tests run in isolated VMs to avoid affecting the host machine:
+- **macOS**: Vagrant + UTM plugin with Ubuntu 24.04 Desktop (`vagrant up --provider=utm`)
+- **Linux**: Multipass with Ubuntu 24.04 (`./tests/test_linux.sh`)
+
+See [tests/README.md](tests/README.md) for detailed setup instructions.
+
+## Architecture
+
+**install.sh** is the entry point — installs system packages, mise, Ruby, and Node.js, then copies the repo and runs `rake install`.
+
+**Rakefile** is the installer — symlinks files, runs `mac.sh` or `ubuntu.sh` for platform-specific prerequisites, and sets up plugins.
+
+**mac.sh / ubuntu.sh** install platform-specific dependencies (Homebrew packages on macOS, Docker/tmux/Gogh on Ubuntu).
+
+**Customization layer**: Every config file sources a `.local` counterpart if present. Users put personal overrides in `.local` files rather than modifying the repo.
+
+**Key conventions**:
+- Vim leader key is `<Space>`
+- Tmux prefix is `C-a` (not the default `C-b`)
+- Zsh uses vi mode with `jj` bound to escape
+- Default colorscheme is gruvbox (dark background)
+- Vim plugin manager is [vim-plug](https://github.com/junegunn/vim-plug) (`~/.vim/plugins.vim`)
+- Vim settings are auto-loaded from `vim/settings/*.vim`
+- Zsh functions are auto-loaded from `zsh/functions/*`
+- Zsh theme is `peepcode` (`zsh/themes/peepcode.theme`)
+- Ruby and Node.js managed by [mise](https://mise.jdx.dev)
+
+**Shell aliases** (`aliases`): git shortcuts (`gs`=status, `gco`=checkout, `gp`=push, `gpsh`=push current branch), docker compose aliases (`dc`, `dcr`, `dcup`), and Rails/Ruby aliases (`rc`, `rs`, `rdm`).
+
+**Git config** (`git/gitconfig`): patience diff algorithm, vimdiff as merge tool, rerere enabled, push default is `simple`. Local overrides via `~/.gitconfig.local`.

-====================
+# Campus Code Dotfiles

-## Source of inspiration
+A shared dotfiles distribution for **zsh**, **vim**, **tmux**, and **git**, targeting macOS and Ubuntu.
 
-Our dotfiles are based on following amazing dotfiles:
+Inspired by [Skwp Dotfiles](https://github.com/skwp/dotfiles) and [ThoughtBot Dotfiles](https://github.com/thoughtbot/dotfiles).
 
-[Skwp Dotfiles](http://github.com/skwp/dotfiles)
+## What's included
 
-[ThoughtBot Dotfiles](http://github.com/thoughtbot/dotfiles)
+- **Zsh** with vi mode, custom theme (peepcode), syntax highlighting, and extensive aliases
+- **Vim** with vim-plug, gruvbox colorscheme, ALE linting, NERDTree, CtrlP, and tmux integration
+- **Tmux** with `C-a` prefix, vim-aware pane navigation, battery status, and vi copy mode
+- **Git** with aliases, patience diff, vimdiff merge tool, and rerere enabled
+- **mise** for Ruby and Node.js version management
+- **Docker** and Docker Compose via [OrbStack](https://orbstack.dev) (macOS) or Docker CE (Linux, optional)
 
-## Requirements
-
-* Zsh
-* [Ag](https://github.com/ggreer/the_silver_searcher)
-* [ITerm 2 (Mac)](https://www.iterm2.com/index.html)
-* MVim (Mac) or GVim (Linux)
-* [Gruvbox](https://github.com/morhetz/gruvbox)
-* Tmux
-
-## Pre-Requirements
+## Pre-requisites
 
 - curl
 
-Ubuntu
+On Ubuntu, if not already installed:
 
-- `sudo apt-get install -y curl`
+```bash
+sudo apt-get install -y curl
+```
 
 ## Install
 
-Run follow command:
-
+```bash
+bash -c "$(curl -fSs https://raw.githubusercontent.com/campuscode/cc_dotfiles/master/install.sh)"
 ```
-sh -c "`curl -fSs https://raw.githubusercontent.com/campuscode/cc_dotfiles/master/install.sh`"
+
+You will be prompted for your password to change the default shell to zsh.
+
+For local development installs (from a cloned repo):
+
+```bash
+LOCAL_INSTALL=1 bash install.sh
 ```
 
-Type your password to change your default shell to `zsh`
+## Customization
 
-## Docs
+Every config file sources a `.local` counterpart if present. Place your personal overrides in these files rather than modifying the repo directly:
+
+| File | Purpose |
+|---|---|
+| `~/.aliases.local` | Custom shell aliases |
+| `~/.zshrc.local` | Zsh configuration overrides |
+| `~/.zshenv.local` | Environment variables |
+| `~/.vimrc.local` | Vim settings and colorscheme |
+| `~/.plugins.vim.local` | Additional vim plugins |
+| `~/.tmux.conf.local` | Tmux configuration overrides |
+| `~/.gitconfig.local` | Git user name, email, and overrides |
+| `~/.secrets` | API keys and tokens (not tracked by git) |
 
-[Vim Key Mapping](Vim.md)
+## Key conventions
 
-[Tmux Key Mapping](Tmux.md)
+- **Vim leader**: `<Space>`
+- **Tmux prefix**: `C-a`
+- **Zsh vi mode**: `jj` to escape
+- **Colorscheme**: gruvbox (dark)
+
+## Docs
 
-#### It's easy to make your customization
+- [Vim Key Mapping](Vim.md)
+- [Tmux Key Mapping](Tmux.md)
+- [Testing](tests/README.md)
 
-Place your customization in the following files:
+## Options
 
-* .aliases.local
-* .secrets
-* .zshrc.local
-* .vimrc.local
-* .zshenv.local
-* .plugin.vim.local
-* .tmux.conf.local
-* .gitconfig.local
