 # Quick Start
 
-```bash
-mv ~/.ssh/config ~/.ssh/config_og
-python3 src/ssh_config_to_yaml.py ~/.ssh/config_og --out ~/.ssh/config.yaml
-# Do some edits on ~/.ssh/config.yaml. The migration script won't compress

+Convert your `~/.ssh/config` into an `~/.ssh/config.yaml` by following the rules
+below. Eventually we hope to have a conversion script, but not yet...
 
-As a proof of concept, you can even chain the scripts! The order of hosts will
-change, but the config should function identically!
+Run `src/main.py` on your `~/.ssh/config.yaml` to convert it!
+
+## Systemd Integration
+
+You can have systemd automatically run ssh_compose_pro when your yaml file
+changes!
+
+Move the files under `systemd/` to `~/.config/systemd/user` and update the paths
+to match your system. Next:
 
 ```bash
-python3 src/main.py <(python3 src/ssh_config_to_yaml.py ~/.ssh/config)
+systemctl --user enable --now ssh-compose-pro.path
+journalctl --user -fu ssh-compose-pro.service
 ```
 
+Make a change to your yaml file, and you should see the output appear in the
+terminal running `journalctl`. You can ^C the `journalctl` command, it'll still
+update on change.

 # Rules
 
-The `src/ssh_config_to_yaml.py` script will assist in quickly migrating your
-existing config.

 ## SSH Properties
 
 Standard SSH config properties go under the `ssh_props` heading for every host.
