Here, we will speak about :
The code for all officially maintained extension and the core is kept in an unique repository.
It's a mono-repository.
It's kind of majestic monolith.
The core contain the minimum features, then everything is done via extensions.
The core code follow as much as it can the symfony good practices and have a special folder named componenent for bigger thing (components will may have their own independant package one day).
Each extension are facultative.
Keeping all this extensions in one repository permit to test everything is working easily, to understand the code faster and to refactor much quicker.
The skeleton isn't a real skeleton (copy and install).
It's used for testing, demo, using for generating the docs and a few class from skeleton are extracted by the default installer.
Each package (except skeleton, installer and js-helper) is built as a symfony bundle.
The core package required a symfony app instaled to be functionnal.
Want a particular details about the way the code is organized ?
Feel free to ask (github or mail), I will list my answer here.
This is only for contribution, if you are searching to developp a new application with Pushword, see installation.
