• The word controlles is misspelled; it should be controllers.

- Last are the UI components hosted in [@multiversx/sdk-dapp-ui](https://github.com/multiversx/mx-sdk-dapp-ui) with some components controlled on demand by classes defined in `controlles` and `managers`

• The word consitst is misspelled; it should be consist.

`sdk-dapp` needs to make use of visual elements for allowing the user to interact with some providers (like the ledger), or to display messages to the user (like idle states or toasts). These visual elements consitst of webcomponents hosted in the `@multiversx/sdk-dapp-ui` package. Thus, `sdk-dapp` does not hold any UI elements, just business logic that controls external components. We can consider two types of UI components: internal and public. They are differentiated by the way they are controlled: internal components are controlled by `sdk-dapp`'s signing or logging in flows, while public components should be controlled by the dApp.
