 # dotfiles
+
+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.

+NAME
+    riot - connect to remote hosts using SSH presets
+
+SYNOPSIS
+    ${0##*/} [OPTION]... REMOTE [OPTION]... [COMMAND [COMMAND-ARG]...]
+
+DESCRIPTION
+    Connect to REMOTE using the matching configuration from riot-config.sh.
+    COMMAND defaults to ssh. Separate multiple remotes with commas and jump
+    hosts with slashes. OPTIONs may appear before COMMAND. Once COMMAND is
+    found, all remaining arguments are passed to it without further parsing.
+
+OPTIONS
+    -4
+        Force ssh to use IPv4 addresses only.
+
+    -6
+        Force ssh to use IPv6 addresses only.
+
+    -D, --dry-run
+        Print commands without executing them.
+
+    -d, --dev
+        Enable shell execution tracing.
+
+    -g, --gpg
+        Forward the local GPG agent during an interactive SSH login. Use only
+        with trusted remote hosts.
+
+    -h, --help
+        Display this help and exit.
+
+    -l, --lite
+        Enable dotfiles lite mode for loaded configuration.
+
+    -o SSH-OPTION
+        Pass an option to ssh. This option may be specified multiple times.
+
+    -p, --password
+        Use password authentication instead of public-key authentication.
+
+    -q, --quiet
+        Enable dotfiles quiet mode for loaded configuration.
+
+    -t, --trust
+        Trust the remote and enable X11 and SSH agent forwarding.
+
+    -v
+        Enable verbose ssh output.
+
+    --color
+        Force colored output.
+
+    --tmux
+        Open SSH sessions in tmux windows.
+
+    --
+        End option parsing.
+
+COMMANDS
