Pick a team and channel

A team is a collection of people, conversations, files, and tools — all in one place. A channel is a discussion in a team, dedicated to a department, project, or topic.

The best way to get familiar with teams and channels is to pick a team and channel and start exploring!

Select Teams on the left side of the app and then pick a team.

If you're not on a team and want to create one, see Onboard your teams.
Select a channel and explore the Posts, Files, and other tabs.
