# GitLens

GitLens **supercharges** the built-in Visual Studio Code Git capabilities. It helps you to **visualize code authorship** at a glance via Git blame annotations and code lens, **seamlessly navigate and explore** the history of a file or branch, **gain valuable insights** via powerful comparison commands, and so much more.

GitLens provides an unobtrusive blame annotation at the end of the current line, a status bar item showing the commit information (author and date, by default) of the current line, code lens 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 code lens intrusive or the current line blame annotation distracting — no problem, it is easy to [turn them off or change how they behave](#extension-settings).

### Preview
>![GitLens preview](https://raw.githubusercontent.com/eamodio/vscode-gitlens/master/images/gitlens-preview.gif)
>###### Features blame annotations, code lens, status bar details, quick pick menus for navigation and exploration, compare with previous, and more
