In order to properly run the bot, you need to [register a SoundCloud application](http://soundcloud.com/you/apps/new) and [get a YouTube Data API key](https://console.developers.google.com/apis/api/youtube/overview) for it and then feed the API data to the bot through the command line arguments.
The bot can be installed through Go using this command:
go get github.com/icedream/irc-medialink
Then you can find out which options you can pass to the bot directly by running (assuming you put your `$GOPATH/bin` folder into your `PATH`):
irc-medialink --help
You need to at least pass the `--server`, `--youtube-key`, `--soundcloud-id` and `--soundcloud-secret` parameters.
