+# dotfiles
+
+My terminal setup as a one-liner. Works on Debian/Ubuntu, Fedora/RHEL, Arch, and macOS.
+
+## What it gives you
+
+- **zsh** as the login shell
+- **oh-my-zsh** with plugins: `git kubectl zsh-autosuggestions sudo copypath copyfile dirhistory docker docker-compose nvm`
+- **powerlevel10k** prompt with my exact `.p10k.zsh` config
+- **atuin** for searchable, sync-able shell history (works in bash too)
+
+## Install
+
+```sh
+git clone https://github.com/<you>/dotfiles ~/dotfiles
+cd ~/dotfiles && ./install.sh
+```
+
+Or, if you trust me:
+
+```sh
+curl -fsSL https://raw.githubusercontent.com/<you>/dotfiles/main/install.sh | bash
+```
+
+The script is idempotent — re-run it any time to pull updates.
+
+## Machine-specific config
+
+Anything personal (API keys, conda/nvm init, work-laptop paths) goes in
+`~/.zshrc.local`. The shipped `.zshrc` sources it if present, and it's not
+tracked here.
+
+Example `~/.zshrc.local`:
+
+```sh
+# Per-machine overrides
+export EDITOR=nvim
+export GITHUB_TOKEN=...
+
+# nvm (if you installed it)
+export NVM_DIR="$HOME/.nvm"
+[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
+```
+
+## Fonts
+
+Powerlevel10k looks broken without a Nerd Font. Easiest:
+<https://github.com/romkatv/powerlevel10k#meslo-nerd-font-patched-for-powerlevel10k>
+
+Install the four `MesloLGS NF *.ttf` files, then set your terminal font to `MesloLGS NF`.
+
+## Uninstall
+
+```sh
+rm ~/.zshrc ~/.p10k.zsh
+mv ~/.zshrc.backup.<timestamp> ~/.zshrc   # if you want the old one back
+```
