This widget has been forked from a similar repo and has thus inherited a cool color changing feature based on your todoist karma.
Just copy and paste the widgets/todoist directory into your own widgets directory and then drop todoist.rb into the jobs directory.
Update the todoist_token var found in todoist.rb to match your own API token (this is easy to acquire if you haven't done so, you can find it in the Todoist app through Settings -> Account -> API Token. Your API Token will be a string, about 20 alphanumeric characters long.)
Lastly, add the following snippet into your dashboard html page:
<li data-row="1" data-col="1" data-sizex="2" data-sizey="2">
<div data-id="todoist" data-view="Todoist" data-unordered="true" data-title="To Do"></div>
</li>Optionally, if you'd like to limit the size of the list of to-do's set a data-limit on the inner div:
<li data-row="1" data-col="1" data-sizex="2" data-sizey="2">
<div data-id="todoist" data-view="Todoist" data-limit="3" data-unordered="true" data-title="To Do"></div>
