CAN SOMEBODY HELP ME IM NEW

u/SockTaters

Welcome to Dwitter! A good way to get started is to modify the code of the default dweet when you hit "New dweet" or remixing another user's dweet. There's also a discord https://discord.gg/FRt2m2k3AX
u/poppop3520

ok thanks just learning how to code i dont really code that much
u/SockTaters

That's ok. Everyone starts somewhere
