You can change a track's challenge order using the Web UI or the Instruqt CLI.
Click the track whose challenge order you want to change.
Drag (click-hold-move-release) the challenge or challenges to the desired position.
Click Save order.
The Instruqt CLI prefixes challenge directory names with a sequence number. The directory of the first challenge is called 01-CHALLENGE_SLUG, the second 02-CHALLENGE_SLUG, and so on. You can modify these sequence numbers to configure the challenge order.
Open a terminal or code editor.
Change into the track directory whose challenge order you want to change.
Change the sequence numbers of the challenge directories to match a desired order.
