+- Dependencies: `bash`, `ssh`, `fzf`, `jq`, `yq`.
+- Sample config is stored in `sample-config/` and mirrors current script behavior.
+- Documentation language: English.
+- Current task focus: keep README and memory aligned with the working script and sample configuration.

 # mtm-ssh-menu
 
+A Bash SSH target picker built around `fzf` and YAML configuration.
+
+## What it does
+
+- Lists SSH targets from grouped YAML files
+- Supports global defaults for user, port, and jump hosts
+- Supports per-host overrides
+- Can also browse entries from `~/.ssh/known_hosts`
+- Launches `ssh` directly from the selected entry
+
+## Requirements
+
+- `ssh`
+- `fzf`
+- `jq`
+- `yq`
+
+## Usage
+
+```bash
+./mtm-ssh-menu [--config-dir DIR] [-k [user]]
+```
+
+Options:
+
+- `-h`, `--help`: show help
+- `--config-dir DIR`: use a custom configuration directory
+- `-k`, `--known-hosts [user]`: include hosts from `~/.ssh/known_hosts`
+
+By default, the script reads configuration from:
+
+- `~/.config/mtm-ssh-menu/global.yaml`
+- `~/.config/mtm-ssh-menu/hosts/*.yaml`
+
+## Configuration format
+
+### `global.yaml`
+
+```yaml
+ssh:
+  default_user: root
+  default_port: 22
+  default_options: ""
+  jump_hosts:
+    office: "user@192.168.10.11"
+```
+
+### `hosts/dev.yaml`
+
+```yaml
+group: dev
+servers:
+  - name: api-1
+    aliases:
+      - api
+      - backend
+    host: 192.168.10.11
+    user: dev
+    port: 2222
+
+  - name: web-1
+    aliases:
+      - frontend
+      - ui
+    host: 192.168.10.12
+    user: dev
+    port: 22
+```
+
+### `hosts/prod.yaml`
+
+```yaml
+group: prod
+servers:
+  - name: web-1
+    aliases:
+      - frontend
+      - web
+    host: web-1.prod.internal
+    jump_host: office
+```
+
+Each host entry can define:
+
+- `name`
+- `aliases`
+- `host`
+- `user`
+- `port`
+- `jump_host`
+
+## Sample configuration
+
+A complete sample configuration is available in `sample-config/`.
+
+## Notes
+
+- `jump_host` values 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`.
