+# Project configuration
+
+The project is configured with environment variables. Check the example in `.env.example`.
+
+```sh
+# Create .env file and update the configuration
+cp .env.example  .env
+
+# Export all variables
+set -o allexport; source .env; set +o allexport
+```

+## Running Tests
+
+`pytest` package is used as a testing framework. All the tests are int he `tests/` folder.
+`pytest` configuration is in the `pyproject.toml`.
+
+The `Makefile` includes all the necessary commands that could be run from the project root.
+
+```sh
+# Using Makefile
+make test  # run all the tests
+make test.integration  # run only integration tests
+make test.unit  # run only unit tests
+make test.e2e  # run only E2E tests
+```
