If it’s your first time here, you’re basically good to go. But I recommend installing a lightning wallet and connecting it to your account.

On damus (ios), I use wallet of satoshi

On snort.social (desktop) I use alby (which can also help you secure your private key)

Then you can receive bitcoin from other users. Post a note asking for a test zap when you’re done, and you’ll probably receive a little fraction of a bitcoin 👍
