This widget shows the average CPU load among all cores of the machine:

-
-When the load is more than 80% the graph becomes red. You can easily customize the widget by changing colors, step width, step spacing, width and interval.

and calculates the percentage.
+## Customization
+
+It is possible to customize widget by providing a table with all or some of the following config parameters:
+
+| Name | Default | Description |
+|---|---|---|
+| `width` | 50 | Width of the widget |
+| `step_width` | 2 | Width of the step |
+| `step_spacing` | 1 | Space size between steps |
+| `color` | `beautiful.fg_normal` | Color of the graph |
+
+### Example
+
+```lua
+cpu_widget({
+ width = 70,
+ step_width = 2,
+ step_spacing = 0,
+ color = '#434c5e'
+})
+```
+
+The config above results in the following widget:
