-My personal shell environment and command-line tools, mainly for Linux and
-NixOS systems.
-
-It includes configurations for zsh, tmux, Vim, Git, and SSH, together with a
-few utility scripts used across my machines.
-
-## Highlights
-
-- `riot`: an SSH wrapper with host presets, jump hosts, port forwarding, tmux
-  sessions, and optional GPG agent forwarding.
-- `sagt`: an SSH/GPG agent manager with support for PIV, 1Password, and
-  OpenPGP smart cards.
-- zsh aliases and completions for the bundled tools.
-- tmux and Vim configurations with plugin setup.
-- automatic updates with selectable `main`, `dev`, and `latest` channels.

-## Installation
-
-Quick install:
-
-```sh
-curl -fsSL https://dotfiles.cn | bash
-```
-
-Alternatively, clone the repository so the installer can be reviewed first:
-
-```sh
-git clone https://github.com/DictXiong/dotfiles.git ~/dotfiles
-~/dotfiles/install.sh -a
-```
-
-The installer adds small source/include entries to the existing zsh, tmux,
-Vim, and Git configuration files instead of replacing them entirely.
-
-## Useful commands
-
-```sh
-riot --help                 # show the SSH wrapper manual
-sagt                        # start or reuse an ssh-agent
-sagt gpg                    # use gpg-agent as SSH agent
-sagt gpg-pin                # cache the smart-card signature PIN
-dfs update                  # update dotfiles from the selected channel
-dfs config                  # edit machine-specific settings
-```
-
-## Configuration
-
-Machine-specific settings can be placed in:
-
-```text
-~/.config/dotfiles/env
-~/.config/riot-config.sh
-```
-
-This is a personal dotfiles repository. Review the configuration, SSH keys,
-and installation script before using it on another machine.
