FediTips , 
Every Mastodon server has three main timelines:
"Home" - Your main feed, where you see all the accounts and hashtags you follow
"Local" - All the latest public posts by everyone on your server
"Federated" - All the public posts by all the accounts your server has noticed across the Fediverse
(You can also create your own custom timelines using the "Lists" feature.)
There is more info about how to view these timelines and how to use them here:
