+# Utilities
+
+There are often concepts that aren't inherent to a single feature, but rather work with joining different features together. For example, a reset clickable that activates a conversion and resets a tree, which happens to be a common use case but isn't inherent to clickables, conversions, or trees.
+
+These are perfect situations for utilities, and so to encourage creators to learn to identify and take advantage of these situations, a file called `src/data/common.tsx` has been created to demo some of the more common utility functions a project might use. Adding new utilities to this file is encouraged, as is creating utils in general. It also works as a good stepping stone to creating your own features.
