Questions related to the use of the Git version control system (VCS) to as part of the Salesforce development process, including, but not exclusively, with Salesforce DX.
Git is a version control system used widely by enterprise development and open source projects. Git itself is free, open source software. Git repositories are often managed through cloud services like GitHub, GitLab, and BitBucket.
Git plays a major role in the source-based development process used in Salesforce DX; Git repositories and version history form the source of truth for metadata and code in that workflow.
Extensive documentation is available on learning Git, and clients are available for all major operating systems.
