-## Error handling
-
-There are two ways an Affjax request can fail: there's either some problem with the request itself, or the result that comes back is not as expected.
-
-For the first case, these errors will be things like the URL being invalid or the server not existing, and will occur in the `Aff` error channel. The [`try`](https://pursuit.purescript.org/packages/purescript-aff/docs/Effect.Aff#v:try) function can lift these errors out of the error channel so the result of a request becomes `Aff (Either Error (Response _))`.
-
-The latter case occurs when we did get a response for the request, but the result that came back could not be handled in the way that was expected. In these situations the `body` value of the `Response` will be a `Left` value with the error message describing what went wrong.
