-A small Bash utility to browse SSH targets from YAML configuration and connect to them with `fzf`.
+A Bash SSH target picker built around `fzf` and YAML configuration.
 
-## Features
+## What it does
 
-- Interactive selection with `fzf`
+- Lists SSH targets from grouped YAML files
-- Global defaults for SSH user, port, and jump hosts
+- Supports global defaults for user, port, and jump hosts
-- Per-host overrides in grouped YAML files
+- Supports per-host overrides
-- Support for jump hosts via named aliases
+- Can also browse entries from `~/.ssh/known_hosts`
-- Simple, dependency-light Bash script
+- Launches `ssh` directly from the selected entry
 
 ## Requirements

-## Example workflow
-
-1. Create the config directory.
-2. Add `global.yaml` and one or more files under `hosts/`.
-3. Run the script.
-4. Select a target in the menu and connect.

 ## Sample configuration
 
 A complete sample configuration is available in `sample-config/`.

-- The script requires `yq`, `jq`, `ssh`, and `fzf` to be installed.
+- `jump_host` values are resolved by name from `global.yaml`.
-- Jump hosts are resolved by name from `global.yaml`.
 - If a host does not define a user or port, global defaults are used.
+- `default_options` is present in the config but not consumed by the current script.
+- The sample config includes `ssh_options` in one file, but the current script does not consume it yet.
+- When `-k` is used, entries from `known_hosts` are shown with the selected user or `root` by default.
+- `known_hosts` entries use port `22`.
+- The script uses strict Bash mode (`set -euo pipefail`).
+- The script name shown in usage is `sshm`, while the repository file is `mtm-ssh-menu`.
