+GitLens **supercharges** the built-in Visual Studio Code Git capabilities. It helps you to **visualize code authorship** at a glance via inline blame annotations and CodeLens, **seamlessly navigate and explore** the history of a file or branch, **gain valuable insights** via powerful comparision commands, and so much more.
 
 GitLens provides an unobtrusive blame annotation at the end of the selected line, a status bar item showing the commit author and date of the selected line, CodeLens showing the most recent commit and # of authors of the file and/or code block, and many commands for exploring commits and histories, comparing and navigating revisions, stash access, repository status, and more. GitLens is also [highly customizable](#extension-settings) to meet your specific needs — find CodeLens intrusive or the selected line blame annotation distracting — no problem, it is easy to [turn them off or change how they behave](#extension-settings).
