 - `host` is the host application (cra-based).
 - `remote` standalone application (cra-based) which exposes `Button` component.
 
-# Running Demo
+## Setup
 
-Run `pnpm run start`. This will build and serve both `host` and `remote` on ports 3001 and 3002 respectively.
+Run `pnpm install` in this directory to install dependencies for both `host` and `remote`.
 
-- [localhost:3001](http://localhost:3000/) (HOST)
-- [localhost:3002](http://localhost:3002/) (STANDALONE REMOTE)
+## Running Demo
+
+Run `pnpm run start`. This will build and serve both `host` and `remote` on ports 3000 and 3002 respectively.
 
-# Running Cypress E2E Tests
+- [localhost:3000](http://localhost:3000/) (HOST)
+- [localhost:3002](http://localhost:3002/) (STANDALONE REMOTE)
 
-To run tests in interactive mode, run `npm run cypress:debug` from the root directory of the project. It will open Cypress Test Runner and allow to run tests in interactive mode. [More info about "How to run tests"](../../cypress-e2e/README.md#how-to-run-tests)
+## Running Playwright E2E Tests
 
-To build app and run test in headless mode, run `yarn e2e:ci`. It will build app and run tests for this workspace in headless mode. If tets failed cypress will create `cypress` directory in sample root folder with screenshots and videos.
+To run tests in interactive UI mode, run `pnpm test:e2e:ui`.
 
-["Best Practices, Rules amd more interesting information here](../../cypress-e2e/README.md)
+To build the apps, start both servers, and run tests in headless mode, run `pnpm e2e:ci`.
