Version control
VocabularyVersion control records changes to files so particular versions and their relationships can be inspected or recovered.
Explanation or usage
History can help identify when a change occurred and support coordinated work. A recorded version does not guarantee correct software or replace independent backup of needed data. Unrecorded changes and external secrets need separate care.
Common misunderstandings
A repository proves every committed version is correct and preserves every external file automatically.
