+Once done you can run `php vendor/bin/phpunit` in the application root directory to run all tests.
+
+### 📜 Code Standards
+
+PHP code within BookStack is generally to [PSR-2](http://www.php-fig.org/psr/psr-2/) standards. From the BookStack root folder you can run `./vendor/bin/phpcs` to check code is formatted correctly and `./vendor/bin/phpcbf` to auto-fix non-PSR-2 code. Please don't auto-fix code unless it's related to changes you've made otherwise you'll likely cause git conflicts.
+
+### 🐋 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).
