 # The Metin2 Website

+## Development
+
+### Image Building
+
+To build the image, checkout the repo and run either of the following build statements
+
+```shell
+docker build -t metin2/web:test -f docker/image/prod/apache.Dockerfile .
+# or
+docker build -t metin2/web:test -f docker/image/prod/frankenphp.Dockerfile .
+```
+
+If you want to use this image in your deploy project, ensure to update the `WEB_IMAGE` variable in your `.env` to `metin2/web:test`.
+
+### Testing Migrations
+
+To test newly added migrations, use a temporary docker container that attaches to your existing deploy network.
+
+```shell
+docker run --env-file .env --network deploy_default --rm metin2/web:test "php artisan migrate"
+```
+
+Ensure that the rollback of your migration is also working as expected.
+Adapt the `--step` parameter according to the number of migration files you added.
+
+```shell
+docker run --env-file .env --network deploy_default --rm metin2/web:test "php artisan migrate:rollback --step=1"
+```
