 INTRODUCTION                                    *indentLine-introduction*
+This plugin is used for displaying thin vertical lines at each indentation
+level for code indented with spaces. For code indented with tabs, I think
+there is no need to support it, using :set list lcs=tab:\|\ (here is a space)
+can achieve it.
