Bruce Fields Date: Sun, 26 Nov 2006 03:45:02 +0000 (-0500) Subject: Documentation: clarify tutorial pull/merge discussion X-Git-Tag: v1.5.0-rc0~219 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=93ee7823c0a48b7a51ac0e145b5bcc450c805ea4;p=git.git Documentation: clarify tutorial pull/merge discussion Attempt to clarify somewhat the difference between pull and merge, and give a little more details on the pull syntax. I'm still not happy with this section: the explanation of the origin branch isn't great, but maybe that should be left alone pending the use-separate-remotes change; and we need to explain how to set up a public repository and push to it.
