Here are important links to get you started:

• Delegates explorer - delegates.xcash.foundation | Check the registered delegates, and find how to vote for them. This will move a lot during the registration, so put it in your favourites!
• Voting/staking tutorials - docs.xcash.foundation | Start voting now to earn rewards as soon as DPOPS start !
• CLI Wallet 2.0.0 - github.com | You can still use wallet 1.5.0 until block 800,000, but you will need the new wallet 2.0.0 to vote.
• Android wallet 1.1.0-beta - github.com | The newly release android wallet enables you to vote for a delegate directly from your phone.
• Run a delegate node - docs.xcash.foundation | Documentation about the DPOPS and how to get started running a node, and get elected into the top 50.

From now until the block 800,000, the X-Cash blockchain will keep working as before, except for the fact that you can start voting!
