Welcome aboard! Here are a few pointers on how to get started.
There are two main ways of greeting new joiners with GreetBot: via direct messages and via channel messages. Depending on how many members are in your App, how many new teammates you expect to welcome in the future, and how busy your App typically gets you may choose to configure either just a direct message, one or several channel messages, or both.
The first thing GreetBot will ask after installation is which one of these two options you would like to configure. Generally speaking, direct messages are a great tool for sharing guidelines, contact information and resources, whereas channel messages help introduce new joiners to existing team members, and vice versa. Channel messages can also help provide context for the discussions taking place in each particular channel.
Once you complete the initial setup you can always configure additional messages or make changes to existing ones. You can add new channels, switch channels, re-write your messages entirely or disable messages that are no longer necessary. Just type the word settings in chat with GreetBot to get started.
