+### Tests
+You can run tests using the following command: `./vendor/bin/phpunit`
+
+### Code quality - PhpStan
+To check your code with [phpstan](https://phpstan.org/), run `./vendor/bin/phpstan`.
+
+**Remove errors from baseline:**
+While changing the code you might see the following error from the PhpStan
+```
+Ignored error pattern #.... was not matched in reported errors.
+```
+This means that the error is [no longer present](https://phpstan.org/user-guide/ignoring-errors#reporting-unused-ignores) in the code, so you can remove it from the baseline file.
+To do so, run `./vendor/bin/phpstan --generate-baseline=.phpstan/baseline.neon` and commit the changes.
