+
+
+VARIABLES
+---------
+GIT_AUTHOR_IDENT::
+    The author of a piece of code.
+
+GIT_COMMITTER_IDENT::
+    The person who put a piece of code into Git.
+
+GIT_EDITOR::
+    Text editor for use by Git commands.  The value is meant to be
+    interpreted by the shell when it is used.  Examples: `~/bin/vi`,
+    `$SOME_ENVIRONMENT_VARIABLE`, `"C:\Program Files\Vim\gvim.exe"
+    --nofork`.  The order of preference is the `$GIT_EDITOR`
+    environment variable, then `core.editor` configuration, then
+    `$VISUAL`, then `$EDITOR`, and then the default chosen at compile
+    time, which is usually 'vi'.
+ifdef::git-default-editor[]
+    The build you are using chose '{git-default-editor}' as the default.
+endif::git-default-editor[]
+
+GIT_SEQUENCE_EDITOR::
+    Text editor used to edit the 'todo' file while running `git rebase
+    -i`. Like `GIT_EDITOR`, the value is meant to be interpreted by
+    the shell when it is used. The order of preference is the
+    `$GIT_SEQUENCE_EDITOR` environment variable, then
+    `sequence.editor` configuration, and then the value of `git var
+    GIT_EDITOR`.
+
+GIT_PAGER::
+    Text viewer for use by Git commands (e.g., 'less').  The value
+    is meant to be interpreted by the shell.  The order of preference
+    is the `$GIT_PAGER` environment variable, then `core.pager`
+    configuration, then `$PAGER`, and then the default chosen at
+    compile time (usually 'less').
+ifdef::git-default-pager[]
+    The build you are using chose '{git-default-pager}' as the default.
+endif::git-default-pager[]
+
+GIT_DEFAULT_BRANCH::
+    The name of the first branch created in newly initialized repositories.
+
+GIT_SHELL_PATH::
+    The path of the binary providing the POSIX shell for commands which use the shell.
+
+GIT_ATTR_SYSTEM::
+    The path to the system linkgit:gitattributes[5] file, if one is enabled.
+
+GIT_ATTR_GLOBAL::
+    The path to the global (per-user) linkgit:gitattributes[5] file.
+
+GIT_CONFIG_SYSTEM::
+    The path to the system configuration file, if one is enabled.
+
+GIT_CONFIG_GLOBAL::
+    The path to the global (per-user) configuration files, if any.
+
+Most path values contain only one value. However, some can contain multiple
+values, which are separated by newlines, and are listed in order from highest to
+lowest priority.  Callers should be prepared for any such path value to contain
+multiple items.
+
+Note that paths are printed even if they do not exist, but not if they are
+disabled by other environment variables.
