-## setup
-- clone repo
-- create python virtual environment: `python -m venv venv`
-- activate environment: `source venv/bin/activate`
+This project contains UI and API tests for the [DemoQA](https://demoqa.com) QA training platform. Tests are written with [Pytest](https://docs.pytest.org/) and use [Playwright](https://playwright.dev/python/) for browser automation and API requests.
 
-## run tests
-- install requirements: `pip install -r requierements.txt`
-- run tests: `pytest`
+## Setup
 
-## Alternative way of running tests
-- `make install`
-- `make test`,  `make-test-ui` etc. (see [Makefile](./Makefile))
+1. Clone this repository.
+2. Create and activate a virtual environment:
+   ```bash
+   python -m venv venv
+   source venv/bin/activate
+   ```
+3. Install dependencies and Playwright browsers:
+   ```bash
+   pip install -r requirements.txt
+   playwright install --with-deps
+   ```
+4. Copy `.env.example` to `.env` and adjust the `DOMAIN` variable if needed.
 
-## misc
-- after running `make test` reports will be generated under [reports](./reports) folder
+## Running tests
+
+To run all tests use `pytest`:
+
+```bash
+pytest
+```
+
+You can run specific test types using markers:
+
+```bash
+pytest -m ui    # run UI tests only
+pytest -m api   # run API tests only
+```
+
+The provided `Makefile` offers shortcuts:
+
+```bash
+make install   # install dependencies
+make test      # run tests and generate reports
+```
+
+### Reports
+
+After running `make test` reports are stored in the `reports` directory (HTML under `reports/html` and JUnit XML under `reports/xml`).
+
+## Docker
+
+A `Dockerfile` is available to execute the tests inside a container:
+
+```bash
+docker build -t playwright-tests .
+docker run --rm playwright-tests
+```
