And to be fair it's the best documented platform for web development I have worked with. Have you looked at documentations of random npm packages lately? No, fun.
1. An official guide: https://guide.elm-lang.org/ - with a Hello World followed by all the basics.
2. Great docs https://elm-lang.org/docs with search function. Most package I see have all the functions described with examples etc. E.g. https://package.elm-lang.org/packages/elm/browser/latest/Bro...
3. A subreddit and discourse chat where beginners can ask questions and get good answers.
