Nether

Nether is a root advancement in the Nether tab of Minecraft's advancement system, carrying the in-game description "Bring summer clothes." As the root of the Nether tab, it sits at the very top of this branch and is what every other Nether advancement ultimately descends from. The Nether tab covers advancements for exploring and conquering the Nether dimension, from entering the portal to brewing potions. Nether was added in Minecraft 1.12 and is still in the 26.2 advancement set.

It is rated Easy difficulty on this site: can be completed quickly with minimal resources. Good for beginners. Roots cannot be un-earned and exist mainly to unlock the visible tree, so the real progression begins with the advancements hanging beneath it. 8 further advancements branch out of it: Return to Sender, Those Were the Days, Hidden in the Depths, A Terrible Fortress, Who is Cutting Onions?, Oh Shiny, This Boat Has Legs, and Subspace Bubble.

Within the 23 advancements that make up the Nether tab, Nether is the single entry that requires nothing before it. Unlocking it is the gateway to that whole set, so it is usually the first Nether advancement any player earns.

Nether grants no experience directly; as a root advancement its purpose is to open the tab rather than to reward you.

Earning it unlocks 8 follow-on advancements, Return to Sender, Those Were the Days, Hidden in the Depths, A Terrible Fortress, Who is Cutting Onions?, Oh Shiny, This Boat Has Legs, and Subspace Bubble, each of which becomes trackable only once Nether is complete.

Completing every advancement beneath this root clears the entire Nether tab, which contains 23 advancements in total, 7 of them flagged as challenges and 1 as goals. Working down from Nether in tree order is the most efficient way to clear the tab without backtracking.
