+## Quick Launch
+
+Press **Cmd+G** (macOS) or **Ctrl+Shift+G** (Linux/Windows) to open the Quick Launch overlay. It provides a fuzzy search over your tab templates, letting you instantly open a new tab or switch to an existing one.

+- Type to filter templates by name
+- Use **Arrow keys** or **Tab**/**Shift+Tab** to navigate results
+- Press **Enter** to launch, **Escape** to dismiss
+
+## Tab Templates
+
+Tab templates are defined in `sticky_tabs.toml` in your [configuration directory](#configuration). Each template pre-configures a tab with a command, working directory, color, and other settings.
+
+```toml
+[[tabs]]
+name = "Claude"
+command = "claude"
+color = "#7c3aed"
+unique = true
+keep_open = true
+
+[[tabs]]
+name = "Project"
+working_directory = "~/projects/myapp"
+color = "#22c55e"
+
+[[tabs]]
+name = "Dev Server"
+command = "npm"
+args = ["run", "dev"]
+working_directory = "~/projects/myapp"
+keep_open = true
+```
+
+### Template options
+
+| Field | Description |
+|-------|-------------|
+| `name` | Display name shown in Quick Launch and as the tab title |
+| `command` | Command to run (omit for default shell) |
+| `args` | Command arguments (array) |
+| `working_directory` | Initial working directory |
+| `color` | Tab color in hex (`#RRGGBB`) |
+| `theme` | Theme override for this tab |
+| `background_color` | Lock the background color (overrides theme, hex `#RRGGBB`) |
+| `keep_open` | Keep the tab open after the process exits |
+| `unique` | Singleton mode — only one instance of this tab can exist at a time |
+| `auto_start` | Automatically open this tab when cterm starts |
+| `env` | Extra environment variables (table) |
+| `docker` | Docker container config (see below) |
+| `ssh` | SSH remote config (see below) |
+
+### Singleton tabs (`unique = true`)
+
+When a template has `unique = true`, launching it via Quick Launch will **switch to the existing tab** if one is already open, instead of creating a duplicate. This is ideal for tools that should only run once, like AI assistants or long-running servers.
+
+Combined with Quick Launch, this creates a "go to or open" workflow: press **Cmd+G**, type a few characters, hit **Enter**, and you're either switched to your running session or a new one is started — no need to hunt through tabs.
+
+### Docker templates
+
+Templates can launch shells inside Docker containers. Set the `docker` field with a mode (`exec`, `run`, or `devcontainer`):
+
+```toml
+[[tabs]]
+name = "Dev Container"
+color = "#0db7ed"
+unique = true
+[tabs.docker]
+mode = "devcontainer"
+image = "ubuntu:24.04"
+project_dir = "~/projects/myapp"
+shell = "/bin/bash"
+mount_ssh = true
+```
+
+| Field | Description |
+|-------|-------------|
+| `mode` | `exec` (attach to running container), `run` (start new), or `devcontainer` |
+| `container` | Container name/ID (exec mode) |
+| `image` | Image name with tag (run/devcontainer mode) |
+| `shell` | Shell to use inside the container |
+| `project_dir` | Project directory to mount (devcontainer mode) |
+| `docker_args` | Additional docker arguments (array) |
+| `auto_remove` | Remove container on exit (default: true) |
+| `mount_claude_config` | Mount Claude config into container (default: true) |
+| `mount_ssh` | Mount SSH keys into container (default: false) |
+| `mount_gitconfig` | Mount git config into container (default: true) |
+| `workdir` | Working directory inside container |
+
+### SSH templates
+
+Templates can open SSH connections with port forwarding, jump hosts, and more:
+
+```toml
+[[tabs]]
+name = "Production"
+color = "#22c55e"
+unique = true
+[tabs.ssh]
+host = "prod.example.com"
+username = "deploy"
+identity_file = "~/.ssh/prod_key"
+```
+
+| Field | Description |
+|-------|-------------|
+| `host` | Remote host (required) |
+| `port` | SSH port (default: 22) |
+| `username` | SSH username |
+| `identity_file` | Path to private key |
+| `remote_command` | Command to execute on the remote host |
+| `local_forwards` | Local port forwards (array, format: `"local:host:remote"`) |
+| `remote_forwards` | Remote port forwards (array) |
+| `dynamic_forward` | SOCKS proxy port |
+| `jump_host` | Bastion/jump host |
+| `agent_forward` | Forward SSH agent (default: false) |
+| `x11_forward` | Forward X11 (default: false) |
+| `options` | Extra SSH options as key-value pairs (table, passed as `-o`) |
+| `extra_args` | Additional raw SSH arguments (array) |
+
