You should place the file inside of: `$HOME/Library/LaunchAgents` and then enable by running `launchctl load org.ooni.probe.cli.plist`
It assumes you have a `ooniprobe` binary in `~/.ooniprobe/ooniprobe` and a special config file named `/Users/USERNAME/.ooniprobe/config-100sites.json` with a URL limit of 100 sites per run:
```
"nettests": {
"websites_url_limit": 100
},
```
