Star Corgi
Star corgi is just a small application that retrieves your daily horoscope and posts it to the desired slack channel.
How it works: Create an application on slack and install it to any channel, retrieve the link, and assign it to the following var in main.go:
var slackUrl string = "YOUR_SLACK_URL"
Then you can fill the desired horoscopes to retrieve on the main code:
func main() {
guidance("aries")
}
