This is a very vague question that leaves very little room for help.
What exactly do you need help with? The pinned thread in this forum is a very good overview of what's need to get streaming and submitting runs. I'd recommend reading that and figuring out what in specific you need help with or more guidance on. Then I'm sure we'd be glad to offer advice or instructions for whatever you need.
Here are some resources to help you out: Streaming/Recording FAQ: https://www.speedrun.com/streaming_recording_equipment/thread/qlnmy Kirby: NiDL any% guide: https://www.speedrun.com/knidl/guide/u8n6m Differences between Platform and Emulator runs: https://www.speedrun.com/knidl/thread/3rnvd
Next time please be a bit more clear with your question, none of us here are really sure what you need help with.
