Hi Andrew,
If you go into the Marketing Activities section of your instance, you'll see a button called "new" with some blue rectangles beside it (it'll be in the upper/mid section of your browser window to the left/center).
Click on it and then select "Import Program" from the drop down. In the pop up window, select "Marketo Program Library" for the subscription and then choose to import "Lead Lifecycle 2"
As Marketo describes it, this is
"A group of campaigns that track the status of a lead and send to Sales when qualified."You'll need to tell it what campaign folder to put these pieces into in the next step. Then Marketo will give you a preview of what you're about to download in the third and final step.
This will import everything you need for lead scoring right into your instance! Simply go thorugh and modify scoring and alerting as is necessary for your organization. Voila, basic lead scoring in a snap!
