Pull requests, bug reports, and all other forms of contribution are welcomed and highly encouraged! 
The project is using Docker as a dev environment. However, you can use anything you want.
If you want to use the built-in environment, make sure to install Docker on your machine and then just run this command in the devops folder.
make runI use makefiles as abstraction layer. So you find all kinds of commands that you can run. Just run this command (recommended inside the container of the Dev-Environment) and hit ENTER. Then you see a list of commands that you can use.
make [ENTER]
# sample of commands
make dev
make phpunit
make buildPlease make sure the code is as simple as possible. Try to code as if it would just work, and just fail-fast if something is breaking. Don't try to do all kinds of try/catch blocks that increases complexity and chances for side effects.
Also try to create comments where things might not be clear.
I'm super happy to accept pull requests! Here's a quick guide on how to make my life easier when reviewing it.
I did my best to create a good CI pipeline to avoid as many problems as possible. To already check if your code is good to go, you can run the following command locally before doing a Pull Request.
make prThis will run the fixers and all tests from the pipeline. So it can be that your GIT tool shows changes afterwards from the fixers, just commit these to your branch.
If this command runs completely through, the pipeline on Github will also pass.
If you want to increase the coverage of unit tests you can open the generated HTML report inside the folder .reports/phpunit/coverage and check what could be improved. Besides this report, there are many more that you can use.
Please create a changelog entry for your changes. This can be done by adding a line to the CHANGELOG.md file.
This helps me to keep track of what has changed and to create a new release later on.
THANK YOU FOR YOUR HELP
