Hi
The README does describe the functions, but is quite sparse in giving examples.
Under "Getting Started" we get two code examples, but further examples for 'init', 'changeMode', 'getRoot', 'create', 'decode', 'subscribe', 'listen', 'attach', 'fetch' and 'fetchSingle' are missing.
Sometimes examples just makes things way easier to understand and get started with. Hope this gets added in the future for each of the given parts in the readme.
