 Get the github user contribution grid
 
+## Usage
+
+```js
+const { cells, colorScheme } = await getGithubUserContribution("platane");
+
+// colorScheme = [
+//    "#ebedf0",
+//    "#9be9a8",
+//    ...
+// ]
+// cells = [
+//    {
+//      x: 3,
+//      y: 0,
+//      count: 3,
+//      color: '#ebedf0',
+//      date:'2019-01-18'
+//    },
+//    ...
+// ]
+```
+
 ## Implementation
 
 Based on the html page. Which is very unstable. Might switch to using github api but afaik it's a bit complex.
