You should note that static content such as images and JavaScript or CSS files must be cross-mounted between the `mybb` and `nginx` containers - as PHP-FPM is not capable of serving those natively.

# Preserving existing files

If you wish to run this image and preserve any updated `lang` or `config` files, you can add the following flag:

```
docker run mybb/mybb --skip-old-files php-fpm
```

or, within your compose file, specify the following command argument:

```yaml
services:
mybb:
image: mybb/mybb:latest
command: --skip-old-files php-fpm
volumes:
- ${PWD}/mybb:/var/www/html:rw

...
```

# How to build this image

You must provide four build-time arguments when building this Docker image; `BUILD_AUTHORS`, `BUILD_DATE`, `BUILD_SHA1SUM` and `BUILD_VERSION`.
