read-tree.txt: clarify --reset and worktree changes The description of --reset stays true to the first implementation in 438195cced (git-read-tree: add "--reset" flag, 2005-06-09). That is, --reset discards unmerged entries. Or at least true to the commit message because I can't be sure about read-tree's behavior regarding local changes. But in fcc387db9b (read-tree -m -u: do not overwrite or remove untracked working tree files., 2006-05-17), it is clear that "-m -u" tries to keep local changes, while --reset is singled out and will keep overwriting worktree files. It's not stated in the commit message, but it's obvious from the patch. I went this far back not because I had a lot of free time, but because I did not trust my reading of unpack-trees.c code. So far I think the related changes in history agree with my understanding of the current code, that "--reset" loses local changes. This behavior is not mentioned in git-read-tree.txt, even though old-timers probably can just guess it based on the "reset" name. Update git-read-tree.txt about this. Side note. There's another change regarding --reset that is not obviously about local changes, b018ff6085 (unpack-trees: fix "read-tree -u --reset A B" with conflicted index, 2012-12-29). But I'm pretty sure this is about the first function of --reset, to discard unmerged entries correctly. PS. The patch changes one more line than necessary because the first line uses spaces instead of tab.

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-.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 Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just “subscribe git” in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://public-inbox.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
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):
