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.
