 First install the `inotify-tools` (seems to be named like that in all major distros): 
 test that it works by calling `inotifywait -h`.
 
-Prepare a Google Drive folder in your $HOME directory with `grive -a`.
+Ensure you have first initialized a Google Drive folder per the instructions in the usage section.
+Execute these commands from the directory above the folder you are using. In the example below,
+`google-drive` was initialized inside the user `$HOME` directory.
 
 ```bash
-# 'google-drive' is the name of your Google Drive folder in your $HOME directory
 systemctl --user enable grive-timer@$(systemd-escape google-drive).timer
 systemctl --user start grive-timer@$(systemd-escape google-drive).timer
 systemctl --user enable grive-changes@$(systemd-escape google-drive).service
 systemctl --user start grive-changes@$(systemd-escape google-drive).service
 ```
 
+For example:
+```
+$ systemctl --user enable grive-timer@$(systemd-escape google-drive).timer
+Created symlink /home/<user>/.config/systemd/user/timers.target.wants/grive-timer@google\x2ddrive.timer → /usr/lib/systemd/user/[email protected].
+$ systemctl --user start grive-timer@$(systemd-escape google-drive).timer
+$ systemctl --user enable grive-changes@$(systemd-escape google-drive).service
+Created symlink /home/<user>/.config/systemd/user/default.target.wants/grive-changes@google\x2ddrive.service → /usr/lib/systemd/user/[email protected].
+$ systemctl --user start grive-changes@$(systemd-escape google-drive).service
+```
+
+You can check the status of these services as so:
+```
+$ systemctl --user status grive-timer@$(systemd-escape google-drive).timer
+● grive-timer@google\x2ddrive.timer - Google drive sync (fixed intervals)
+     Loaded: loaded (/usr/lib/systemd/user/[email protected]; enabled; vendor preset: enabled)

+
+Tail the service unit to gauge the current activity:
+```
+journalctl --user -f -u grive-timer@$(systemd-escape google-drive).service
+```
+
 You can enable and start these two units for multiple folders in your `$HOME`
 directory if you need to sync with multiple google accounts.
