 ## Tasks
 
+The following tasks purposefully leave out some specificity to allow you to
+demonstrate your problem-solving skills, and give you the opportunity to make
+decisions about the implementation.
+
+Each task should only take about 30 minutes to complete, and you should also allow 30 minutes to familiarize yourself with the codebase. If you find yourself spending more time on a task, submit what you have and document in the PR what you would have done if you had more time.
