+### Manual Install
+
+```bash
+# 1. Clone the repository
+git clone https://github.com/m1ngsama/chopsticks.git ~/.vim
+
+# 2. Create symlink
+ln -sf ~/.vim/.vimrc ~/.vimrc
+
+# 3. Install vim-plug
+curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
+    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
+
+# 4. Open Vim and install plugins

+Add to your `~/.bashrc` or `~/.zshrc`:
+```bash
+export TERM=xterm-256color
+```
+
+## Customization
+
+The `.vimrc` file is well-organized into sections:
+
+1. **General Settings** (lines 1-150) - Basic Vim behavior
+2. **Plugin Management** (lines 151-230) - Plugin list
+3. **Key Mappings** (lines 300-400) - Custom shortcuts
+4. **Plugin Settings** (lines 400-600) - Plugin configurations
+
+To customize:
+1. Open `~/.vim/.vimrc`
+2. Find the section you want to modify
+3. Make your changes
+4. Reload with `:source ~/.vimrc` or restart Vim
+
+### Common Customizations
+
+**Change colorscheme:**
+```vim
+" In .vimrc, find the colorscheme line and change to:
+colorscheme dracula
+" or: solarized, onedark, gruvbox
+```
+
+**Change leader key:**
+```vim
+" Default is comma (,), change to space:
+let mapleader = " "
+```
+
+**Disable relative line numbers:**
+```vim
+set norelativenumber
+```
+
+## Next Steps
+
+1. Read the full [README.md](README.md) for complete documentation
+2. Check out `:help` in Vim for built-in documentation
