Configuring the lab completion order

To make passing the lab exercises in the specified order mandatory (first exercise 1, then exercise 2 and so forth):

1. For the required lab, open CODE.
2. Click course-config.json and in the editor pane set the sequential_walkthrough_order parameter to true:

"sequential_walkthrough_order": true,

If you want to allow learners to take exercises in any order at their choice, set the sequential_walkthrough_order value to false.
