Development System Setup

You can have any number of development systems, provided the following is true of all of them:

They all run Magento 2.2 or later
All Magento code is under source control in the same repository as the build and production systems
Each development system should use either default mode or developer mode
It has Magento file system ownership and permissions set as discussed in Prerequisite for your development, build, and production systems.
Make sure all of the following are excluded from source control:
- vendor directory (and subdirectories)
- generated directory (and subdirectories)
- pub/static directory (and subdirectories)
- app/etc/env.php file
Make sure app/etc/config.php is included in source control

If you use Git, Magento’s .gitignore provides most of the preceding. See the .gitignore reference for more information.
