Hey there! 
Welcome to Episode! I recommend starting with Joseph Evans’ tutorials on YouTube, they’re super helpful and that’s where pretty much every author started 
I also made a thread some time ago about how to write a successful story - Writing an Episode story 101 - The key to success
If you need help just ask here on the forums, there’s always someone ready to help. You can also go ahead and message me on Insta any time! @martini.episode
