+## Contributing a new country
+
+If you want to add a new country, you can create a pull request.
+
+1. Create a new class in the `Countries` directory. It should extend the `Country` class.
+2. Add a test for the new country in the `tests` directory.
+3. Run the tests so a snapshot gets created.
+4. Verify the result in the newly created snapshot is correct.
+
+In case your country has specific rules for calculating holidays,
+for example region specific holidays, you can pass this to the constructor of your country class.
+
+```php
+$holidays = Holidays::for(Austria::make(region: 'de-bw'))->get();
+```
+
+The value, `de-bw`, will be passed to the region parameter of the contructor of a country.
+
+```php
+class Austria extends Country
+{
+    protected function __construct(
+        protected ?string $region = null,
+    ) {
+    }
+
+    protected function allHolidays(int $year): array
+    {
+        // Here you can use $this->region (or other variables) to calculate holidays
+    }
+```
