| This is [Git for Windows](http://git-for-windows.github.io/), the Windows port | ||
| of [Git](http://git-scm.com/). | ||
| This is Microsoft Git, a special Git distribution to support monorepo scenarios. If you are _not_ working in a monorepo, you are likely searching for [Git for Windows](http://git-for-windows.github.io/) instead of this codebase. | ||
|
|
||
| The Git for Windows project is run using a [governance | ||
| model](http://git-for-windows.github.io/governance-model.html). If you | ||
| encounter problems, you can report them as [GitHub | ||
| issues](https://github.com/git-for-windows/git/issues), discuss them on Git | ||
| for Windows' [Google Group](http://groups.google.com/group/git-for-windows), | ||
| and [contribute bug | ||
| fixes](https://github.com/git-for-windows/git/wiki/How-to-participate). | ||

||
| Git - fast, scalable, distributed revision control system | ||
| Why is Microsoft Git needed? | ||
| ========================================================= | ||
|
|
||
| Git is a fast, scalable, distributed revision control system with an | ||
| unusually rich command set that provides both high-level operations | ||
| and full access to internals. | ||
|
|
||
| Git is an Open Source project covered by the GNU General Public | ||
| License version 2 (some parts of it are under different licenses, | ||
| compatible with the GPLv2). It was originally written by Linus | ||
| Torvalds with help of a group of hackers around the net. | ||
|
|
||
| Please read the file [INSTALL][] for installation instructions. | ||
|
|
||
| Many Git online resources are accessible from <https://git-scm.com/> | ||
| including full documentation and Git related tools. | ||
|
|
||
| See [Documentation/gittutorial.txt][] to get started, then see | ||
| [Documentation/giteveryday.txt][] for a useful minimum set of commands, and | ||
| `Documentation/git-<commandname>.txt` for documentation of each command. | ||
| If git has been correctly installed, then the tutorial can also be | ||
| read with `man gittutorial` or `git help tutorial`, and the | ||
| documentation of each command with `man git-<commandname>` or `git help | ||
| <commandname>`. | ||
|
|
||
| CVS users may also want to read [Documentation/gitcvs-migration.txt][] | ||
| (`man gitcvs-migration` or `git help cvs-migration` if git is | ||
| installed). | ||
|
|
||
| The user discussion and development of core Git take place on the Git | ||
| mailing list -- everyone is welcome to post bug reports, feature | ||
| requests, comments and patches to [email protected] (read | ||
| [Documentation/SubmittingPatches][] for instructions on patch submission). | ||
| To subscribe to the list, send an email with just "subscribe git" in | ||
| the body to [email protected]. The mailing list archives are | ||
| available at <https://lore.kernel.org/git/>, | ||
| <http://marc.info/?l=git> and other archival sites. | ||
| The core git mailing list is plain text (no HTML!). | ||
|
|
||
| Issues which are security relevant should be disclosed privately to | ||
| the Git Security mailing list <[email protected]>. | ||
|
|
||
| The maintainer frequently sends the "What's cooking" reports that | ||
| list the current status of various development topics to the mailing | ||
| list. The discussion following them give a good reference for | ||
| project status, development direction and remaining tasks. | ||
|
|
||
| The name "git" was given by Linus Torvalds when he wrote the very | ||
| first version. He described the tool as "the stupid content tracker" | ||
| and the name as (depending on your mood): | ||
|
|
||
| - random three-letter combination that is pronounceable, and not | ||
| actually used by any common UNIX command. The fact that it is a | ||
| mispronunciation of "get" may or may not be relevant. | ||
| - stupid. contemptible and despicable. simple. Take your pick from the | ||
| dictionary of slang. | ||
| - "global information tracker": you're in a good mood, and it actually | ||
| works for you. Angels sing, and a light suddenly fills the room. | ||
| - "goddamn idiotic truckload of sh*t": when it breaks | ||

| Git is awesome - it's a fast, scalable, distributed version control system with an unusually rich command set that provides both high-level operations and full access to internals. What more could you ask for? | ||
|
|
||
| Well, because Git is a distributed version control system, each Git repository has a copy of all files in the entire history. As large repositories, aka _monorepos_ grow, Git can struggle to manage all that data. As Git commands like `status` and `fetch` get slower, developers stop waiting and start switching context. And context switches harm developer productivity. | ||
|
|
||
| Microsoft Git is focused on addressing these performance woes and making the monorepo developer experience first-class. It does so in part by working with the [GVFS protocol](https://docs.microsoft.com/en-us/azure/devops/learn/git/gvfs-architecture#gvfs-protocol) to prefetch packs of commits and trees and delay downloading of associated blobs. This is required for monorepos using [VFS for Git](https://github.com/microsoft/VFSForGit/blob/master/Readme.md). Additionally, some Git hosting providers support the GVFS protocol instead of the Git-native [partial clone feature](https://github.blog/2020-12-21-get-up-to-speed-with-partial-clone-and-shallow-clone/). | ||
|
|
||
| __Note:__ Some Git hosting providers support the GVFS protocol instead of the Git-native [partial clone feature](https://github.blog/2020-12-21-get-up-to-speed-with-partial-clone-and-shallow-clone/). | ||
|
|
||
| Downloading and Installing | ||
| ========================================================= | ||
|
|
||
| If you're working in a monorepo and want to take advantage of Microsoft Git's performance boosts, you can | ||
| download the latest version installer for your OS from the [Releases page](https://github.com/microsoft/git/releases). Alternatively, | ||
| you can opt to install via the command line, using the below instructions for supported OSes: | ||
|
|
||
| ## Windows | ||
| __Note:__ Winget is still in public preview, meaning you currently [need to take special installation steps](https://docs.microsoft.com/en-us/windows/package-manager/winget/#install-winget). | ||
|
|
||
| To install with Winget, run | ||
|
|
||
| ```shell | ||
| winget install microsoft/git | ||
| ``` | ||
|
|
||
| To upgrade Microsoft Git, use the following Git command, which will download and install the latest release. | ||
|
|
||
| ```shell | ||
| git update-microsoft-git | ||
| ``` | ||
|
|
||
| You may also be alerted with a notification to upgrade, which presents a single-click process for running `git update-microsoft-git`. | ||
|
|
||
| ## macOS | ||
|
|
||
| To install Microsoft Git on macOS, first [be sure that Homebrew is installed](https://brew.sh/) then install the `microsoft-git` cask with these steps: | ||
|
|
||
| ```shell | ||
| brew tap microsoft/git | ||
| brew install --cask microsoft-git | ||
| ``` | ||
|
|
||
| To upgrade microsoft/git, you can run the necessary brew commands: | ||
|
|
||
| ```shell | ||
| brew update | ||
| brew upgrade --cask microsoft-git | ||
| ``` | ||
|
|
||
| Or you can run the `git update-microsoft-git` command, which will run those brew commands for you. | ||
|
|
||
| ## Linux | ||
|
|
||
| For Ubuntu/Debian distributions, `apt-get` support is coming soon. For now, though, please use the most recent [`.deb` package](https://github.com/microsoft/git/releases). | ||
|
|
||
| ```shell | ||
| wget https://github.com/microsoft/git/releases/download/v2.31.1.vfs.0.1/git-vfs_2.31.1.vfs.0.1.deb microsoft-git.deb | ||
| sudo dpkg -i microsoft-git.deb | ||
| ``` | ||
|
|
||
| For other distributions, you will need to compile and install microsoft/git from source: | ||
|
|
||
| ```shell | ||
| git clone https://github.com/microsoft/git microsoft-git | ||
| cd microsoft-git | ||
| make -j12 prefix=/usr/local | ||
| sudo make -j12 prefix=/usr/local install | ||
| ``` | ||
|
|
||
| For more assistance building Git from source, see [the INSTALL file in the core Git project](https://github.com/git/git/blob/master/INSTALL). | ||
