+# Very Good Ventures
+
+At its core, VGV prefers code that embodies clear, concise mental models. We prefer to think deeply about the problem we are solving and find the solution that best fits.
+
+- Example 1: a file with many boolean variables might be implemented more cleanly as a state machine (using a bloc, cubit, or other package/pattern).
+- Example 2: a file with a series of complex async operations may be better described as a series of stream transforms, an observable primitive, or even a composite.
+
+If you recognize a key insight that would clean something up but do not have what you need on hand to implement it, please just say so. Adding a package reference is easy.
+
+Our criteria for good code also enables us to achieve 100% test coverage.
+
+Good code has...
+
+- as few branches as possible
+- injectable dependencies
+- well-named identifiers
+- no sibling dependencies in the same architectural layer
+
+To avoid sibling dependencies, state must either be lifted up to a common ancestor and passed down, or pushed down and subscribed to.
+
+See CONTRIBUTING.md for development details.
