-## install
+[(R)age](https://github.com/woodruffw/pyrage) encrypted note-taking CLI app.
+
+`halig` opens, using your favorite `$EDITOR`, an in-memory copy of a file and upon save-and-exit,
+it encrypts the new contents into an [age](https://github.com/FiloSottile/age) file that
+you can store, _relatively_ safe, anywhere.
+
+## Install
 
 ```shell
 pip install halig
 ```
 
-## cli mode
+PS: I recommend using [pipx](https://pypa.github.io/pipx/) instead
+
+## Setup TLDR
 
 ```shell
-$ halig edit some_notebook # edit today's note
-$ halig edit some_notebook/foo # edit  /path/to/some_notebook/foo.age
-$ halig notebooks # list current notebooks
+set -e
+ssh-keygen -t ed25519
+mkdir -p "${XDG_CONFIG_HOME:-$HOME/.config}/halig"
+cat << EOF > "${XDG_CONFIG_HOME:-$HOME/.config}/halig/halig.yml"
+---
+notebooks_root_path: /home/$(id -un)/Documents/Notebooks
+identity_path: /home/$(id -un)/.ssh/id_ed25519
+recipient_path: /home/$(id -un)/.ssh/id_ed25519.pub
+EOF
+```
+
+## Usage TLDR
+
+```shell
+halig edit some_notebook     # edit today's note relative to <notebooks_root_path>/some_notebook
+halig edit some_notebook/foo # edit  <notebooks_root_path>/some_notebook/foo.age
+halig notebooks              # list current notebooks
+
 ```
