+Once done you can run `php vendor/bin/phpunit` in the application root directory to run all tests.

+
+### 🐋 Development using Docker
+
+This repository ships with a Docker Compose configuration intended for development purposes. It'll build a PHP image with all needed extensions installed and start up a MySQL server and a Node image watching the UI assets.
+
+To get started, make sure you meet the following requirements:
+
+- Docker and Docker Compose are installed
+- Your user is part of the `docker` group
+
+If all the conditions are met, you can proceed with the following steps:
+
+1. **Copy `.env.example` to `.env`**, change `APP_KEY` to a random 32 char string and set `APP_ENV` to `local`.
+2. Make sure **port 8080 is unused** *or else* change `DEV_PORT` to a free port on your host.
+3. **Run `chgrp -R docker storage`**. The development container will chown the `storage` directory to the `www-data` user inside the container so BookStack can write to it. You need to change the group to your host's `docker` group here to not lose access to the `storage` directory.
+4. **Run `docker-compose up`** and wait until the image is built and all database migrations have been done.
+5. You can now login with `
[email protected]` and `password` as password on `localhost:8080` (or another port if specified).
+
+If needed, You'll be able to run any artisan commands via docker-compose like so:
+
+```bash
+docker-compose run app php artisan list
+```
+
+The docker-compose setup runs an instance of [MailHog](https://github.com/mailhog/MailHog) and sets environment variables to redirect any BookStack-sent emails to MailHog. You can view this mail via the MailHog web interface on `localhost:8025`. You can change the port MailHog is accessible on by setting a `DEV_MAIL_PORT` environment variable.
+
+#### Running tests
+
+After starting the general development Docker, migrate & seed the testing database:
+
+ ```bash
+# This only needs to be done once
+docker-compose run app php artisan migrate --database=mysql_testing
+docker-compose run app php artisan db:seed --class=DummyContentSeeder --database=mysql_testing
+```
+
+Once the database has been migrated & seeded, you can run the tests like so:
+
+ ```bash
+docker-compose run app php vendor/bin/phpunit
+```

+## 🌎 Translations
+
+Translations for text within BookStack is managed through the [BookStack project on Crowdin](https://crowdin.com/project/bookstack). Some strings have colon-prefixed variables in such as `:userName`. Leave these values as they are as they will be replaced at run-time. Crowdin is the preferred way to provide translations, otherwise the raw translations files can be found within the `resources/lang` path.
+
+If you'd like a new language to be added to Crowdin, for you to be able to provide translations for, please [open a new issue here](https://github.com/BookStackApp/BookStack/issues/new?template=language_request.md).
+
+Please note, translations in BookStack are provided to the "Crowdin Global Translation Memory" which helps BookStack and other projects with finding translations. If you are not happy with contributing to this then providing translations to BookStack, even manually via GitHub, is not advised.
