 --template=<template_directory>::
-	Provide the directory from which templates will be used.
-	The default template directory is `/usr/share/git-core/templates`.

+files rather than the default.  The template files include some directory
+structure, some suggested "exclude patterns", and copies of non-executing

+extensible.
+
+--shared[={false|true|umask|group|all|world|everybody}]::
+
+Specify that the git repository is to be shared amongst several users.  This
+allows users belonging to the same group to push into that
+repository.  When specified, the config variable "core.sharedRepository" is
+set so that files and directories under `$GIT_DIR` are created with the
+requested permissions.  When not specified, git will use permissions reported
+by umask(2).
+
+The option can have the following values, defaulting to 'group' if no value
+is given:
+
+ - 'umask' (or 'false'): Use permissions reported by umask(2). The default,
+   when `--shared` is not specified.
+
+ - 'group' (or 'true'): Make the repository group-writable, (and g+sx, since
+   the git group may be not the primary group of all users).
+
+ - 'all' (or 'world' or 'everybody'): Same as 'group', but make the repository
+   readable by all users.
+
+By default, the configuration flag receive.denyNonFastforward is enabled
+in shared repositories, so that you cannot force a non fast-forwarding push
+into it.

 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.
