 ## Note about `options.extendTypes`
 
-ExandTypes option gives you a flexible way to handle different content-types and modify the defaults which can be found [at utils.defaultTypes function](./utils.js#L83-L104). In addition you can pass combination of `options.extendTypes.custom` and `options.handler`. When the request has some of the "custom" content type, this middleware will call the `handler` **generator** function with `ctx, options, next`. You can see more at [issue #52](https://github.com/tunnckoCore/koa-better-body/issues/52).
