Usage Guide

Questions

• Should the usage guide talk about the .match property on action creators in createAction? (or we could at least link to the API ref)
• Should we show the builder pattern everywhere? These are some good spots to introduce a change:
  • https://redux-toolkit.js.org/usage/usage-guide#async-requests-with-createasyncthunk
  • https://redux-toolkit.js.org/usage/usage-guide#using-createentityadapter-with-normalization-libraries

Ideas for improvements:

• https://redux-toolkit.js.org/usage/usage-guide#defining-async-logic-in-slices - could link to a recipe for a createThunk function
