+
+Shows the contribution graph, similar to the one on the github profile page:
+
+![screenshot](./screenshot.jpg)
+
+## Customization
+
+It is possible to customize the widget by providing a table with all or some of the following config parameters:
+
+| Name | Default | Description |
+|---|---|---|
+| `username` | 'streetturtle' | Username |
+| `days` | `365` | Number of days in the past, more days - wider the widget |
+| `empty_color` | `beautiful.bg_normal` | Color of the days with no contributions |
+| `with_border` | `true` | Should the graph contains border or not |
+| `margin_top` | `1` | Top margin |
+
+Few more screenshots:
+
+1000 days:
+![screenshot1](./screenshot1.jpg)
+
+No borders:
+![screenshot2](./screenshot2.jpg)
+
+
+## Installation
+
+Clone/download repo under **~/.config/awesome** and use widget in **rc.lua**:
+
+```lua
+local github_contributions_widget = require("awesome-wm-widgets.github-contributions-widget.github-contributions-widget")
+...
+s.mytasklist, -- Middle widget
+	{ -- Right widgets
+    	layout = wibox.layout.fixed.horizontal,
+		...
+		-- default
+        github_contributions_widget({username = '<your username>'}),
+		...
+```
