Please add documentation !

I just wanted a use a docker container to develop with PHP and Symfony. The symfony documentation redirected me to your repo, however I have no clue how to develop with the environment I set up with your repo...
When I install new packages on the container, the composer.json locally is not updated, is that normal ? When I add a file in the /src folder locally, the I don't see it in the container...
Maybe I just don't get it and it's a repo to set up a production ready Docker image. Please let me know.

I don't know what to say, the problem you describe seems to be a docker volume synchronization issue and it doesn't seem to be directly related to the default project configuration but either to your overlay or your docker configuration.

Otherwise, the get started is here : https://github.com/dunglas/symfony-docker#getting-started and all the documentation is here : https://github.com/dunglas/symfony-docker#docs
