Make sure you first import or create a Shelley wallet. Older Byron wallets will not offer the delegation features. If necessary, create the new (Shelley) wallet and move your funds from the old wallet to the new one.
In order to delegate to a pool, you will need to know its pool-ID, which can be found on your preferred pool website, or on sites like Pooltool.io or Adapools.org.
The rest is point-and-click. Watch the video below how to proceed.
Delegating to a stake pool from Daedalus is pretty straightforward. Just browse all stakepools directly inside the wallet, visit their websites for more information, or visit pooltool.io or Adapools.org to compare performance data.
