When <paths> are given, this command does \fInot\fR switch branches\&. It updates the named paths in the working tree from the index file (i\&.e\&. it runs git\-checkout\-index \-f \-u)\&. In this case, \-f and \-b options are meaningless and giving either of them results in an error\&. <branch> argument can be used to specify a specific tree\-ish to update the index for the given paths before updating the working tree\&.

-If you have local modifications to a file that is different between the current branch and the branch you are switching to, the command refuses to switch branches, to preserve your modifications in context\&. With this option, a three\-way merge between the current branch, your working tree contents, and the new branch is done, and you will be on the new branch\&.

When a merge conflict happens, the index entries for conflicting paths are left unmerged, and you need to resolve the conflicts and mark the resolved paths with git update\-index\&.

.SH "DESCRIPTION"
-This simply creates an empty git repository \- basically a \&.git directory and \&.git/object/??/, \&.git/refs/heads and \&.git/refs/tags directories, and links \&.git/HEAD symbolically to \&.git/refs/heads/master\&.
+This command creates an empty git repository \- basically a \&.git directory with subdirectories for objects, refs/heads, refs/tags, and templated files\&. An initial HEAD file that references the HEAD of the master branch is also created\&.
+
+
+If \-\-template=<template_directory> is specified, <template_directory> is used as the source of the template files rather than the default\&. The template files include some directory structure, some suggested "exclude patterns", and copies of non\-executing "hook" files\&. The suggested patterns and hook files are all modifiable and extensible\&.
If the $GIT_DIR environment variable is set then it specifies a path to use instead of \&./\&.git for the base of the repository\&.
If the object storage directory is specified via the $GIT_OBJECT_DIRECTORY environment variable then the sha1 directories are created underneath \- otherwise the default $GIT_DIR/objects directory is used\&.
-A shared repository allows users belonging to the same group to push into that repository\&. When specifying \-\-shared the config variable "core\&.sharedRepository" is set to true so that directories under $GIT_DIR are made group writable (and g+sx, since the git group may be not the primary group of all users)\&.

Running git\-init\-db in an existing repository is safe\&. It will not overwrite things that are already there\&. The primary reason for rerunning git\-init\-db is to pick up newly added templates\&.
