At my work we use GitHub to manage all of our code repositories and GitHub Actions for CI/CD. GitHub is already familiar to a large number of developers and makes it easier for them to get started. My team mostly builds webapps, so we have also leveraged VS Code dev containers. This allows all team members to be coding in the same containerized dev environment in Docker with the same setup. GitHub and VS Code containers have dramatically helped reduce our onboarding time.

Thanks for sharing the experience of your team!
