Options:
  -h, --help                     Displays overview of CLI.

                                 When empty string is provided as argument, then
                                 the log file will be stored in user data

                                 cannot be higher than 32.

Arguments:
  urls                           List of URL addresses pointing to individual
                                 online feeds which should be added.
```

You can also add feeds to RSS Guard by passing URLs as command-line parameters. The feed [URI scheme](https://en.wikipedia.org/wiki/Feed_URI_scheme) is supported, so you can call RSS Guard like this:

```powershell
rssguard.exe "feed://archlinux.org/feeds/news"
rssguard.exe "feed:https//archlinux.org/feeds/news"
rssguard.exe "https://archlinux.org/feeds/news"
```

To add a feed directly from your web browser of choice without copying and pasting the URL manually, you have to open RSS Guard with the feed URL passed as an argument. There are [browser extensions](https://addons.mozilla.org/en-US/firefox/addon/open-with/) that allow you to do this.

## Logging
RSS Guard can write its standard and error output to a file with the `--log` option.
