Ask HN: How to get started in electronic music

I've been interested in learning how to make electronic music (e.g. Geometry dash, Undertale, Daft Punk, C418), but there doesn't seem to be any real documentation or tutorials on how to start.

To summarize my question: a.) What are the first 3 steps (or more) to learn to compose music? b.) Any links, resources etc. to share?

Thanks for your time and interest.
