+.SH "NAME"
+git-new-branch \- Create a new branch with correct tracking information\&.
+.SH "SYNOPSIS"
+.sp
+.nf
+\fIgit new\-branch\fR <branch_name>
+\fIgit new\-branch\fR \-\-upstream_current <branch_name>
+\fIgit new\-branch\fR \-\-upstream <REF> <branch_name>
+\fIgit new\-branch\fR \-\-lkgr <branch_name>
+.fi
+.sp
+.SH "DESCRIPTION"
+.sp
+Creates a new branch\&. By default the new branch will track the configured upstream for the repo (defaults to \fIorigin/master\fR)\&. If one of the other options is specified, it will track that other ref instead\&.
+.sp
+Conceptually, each branch in your repo represents one \fIChange List (CL)\fR\&. If you have many independent CLs (i\&.e\&. the changes in one do not interact with/depend on the changes in another), then you should create them as new branches tracking the default upstream (i\&.e\&. git new\-branch <branch_name>)\&. If you have features which depend on each other, you should create stacked branches using git new\-branch \-\-upstream_current <branch_name>\&.
+.SH "OPTIONS"
+.PP
+\-\-upstream_current
+.RS 4
+Set the tracking (upstream) branch to the currently\-checked\-out branch\&.
+.RE

+\-\-uptstream <REF>
+.RS 4

+.SH "CONFIGURATION VARIABLES"
