-* turn on with `:call EnableGitGutter()`
-* toggle with `:call ToggleGitGutter()`.
+* turn off with `:DisableGitGutter`
+* turn on with `:EnableGitGutter`

-* turn off with `:call DisableGitGutterLineHighlights()`
-* toggle with `:call ToggleGitGutterLineHighlights()`.
+* turn on with `:EnableGitGutterLineHighlights`

 Furthermore you can jump between hunks:

-* jump to previous hunk: `:call GitGutterPrevHunk()`.
+* jump to next hunk: `:GitGutterNextHunk`
+* jump to previous hunk: `:GitGutterPrevHunk`.
