-| `username` | 'streetturtle' | Username |
+| `username` | `streetturtle` | GitHub username |

-| `empty_color` | `beautiful.bg_normal` | Color of the days with no contributions |
+| `color_of_empty_cells` | Theme's default | Color of the days with no contributions |
 | `with_border` | `true` | Should the graph contains border or not |
 | `margin_top` | `1` | Top margin |
+| `theme` | `standard` | Color theme of the graph, see below |
 
-Few more screenshots:
+_Note:_ widget height is 21px (7 rows of 3x3 cells). So it would look nice on the wibar of 22-24px height.
