Lightweight tags in Git provide a simple way to mark specific commits without storing additional metadata, making them perfect for temporary or internal version references. With over 25 years of version control experience and as the creator of CoreUI, I use lightweight tags for development milestones and quick commit references. The most straightforward approach is using the basic git tag command without any flags to create a simple pointer to a commit. This provides fast, lightweight version marking without the overhead of annotated tags and their associated metadata.
