 # Saleor App Bridge
 
-## Installation
+**DEPRECATED**
 
-```bash
-npm i @saleor/app-bridge
-```
-
-## Usage
-
-First initialize the package by running `createApp()`:
-
-```js
-import { createApp } from "@saleor/app-bridge";
-
-const app = createApp();
-```
-
-Access app state:
-
-```js
-const { token, domain, ready, id } = app.getState();
-```
-
-## Events
-
-Events are messages that originate in Saleor Dashboard.
-
-### Available methods
-
-**`subscribe(eventType, callback)`** - can be used to listen to particular event type. It returns an unsubscribe function, which unregisters the callback.
-
-Example:
-
-```js
-const unsubscribe = app.subscribe("handshake", (payload) => {
-  setToken(payload.token); // do something with event payload
-  const { token } = app.getState(); // you can also get app's current state here
-});
-
-// unsubscribe when callback is no longer needed
-unsubscribe();
-```
-
-**`unsubscribeAll(eventType?)`** - unregisters all callbacks of provided type. If no type was provided, it will remove all event callbacks.
-
-Example:
-
-```js
-app.unsubscribeAll("handshake"); // unsubscribe from all handshake events
-
-app.unsubscribeAll(); // unsubscribe from all events
-```
-

-```js
-import { actions } from "@saleor/app-bridge";
-
-const handleRedirect = async () => {
