+
+## Code Quality
+
+<!-- TODO: Complete This Section with examples -->
+
+## Contributing Features
+
+When contributing features, these points should be ensured:
+
+### Invisible until Required
+
+We strive to make Frappe Books as easy and simple to use as possible, and
+Progressive Disclosure is one of the design patterns that enables us to do this.
+
+- **Big Features**: ensure that the feature should be hidden using feature
+  flags unless needed by majority users. Example: inventory features are
+  hidden until _Enable Inventory_ is checked in the Settings.
+
+- **Small Features**: ensure that they stay hidden until needed until the
+  context is relevant. Example: extra fields in the Invoice Items table aren't
+  shown unless the User clicks on the Edit Row button.
+
+Added feature should not silently alter existing functionality until the user is
+aware of it.
+
+### Simple UI
+
+A few rules of thumb to follow if your contributions alters the UI.
+
+- Do not crowd the UI.
+- Ensure even spacing, most spacing and sizes are an even multiple of `1rem`.
+- Ensure vertical and horizontal alignment. For text ensure vertical baseline
+  alignment.
+- Simple Labels, ideally just a single word. Avoid overflow and word-breaks.
+- Child tables should have at most 5 columns. Extra columns should should be
+  jadded to the row edit form.
+
+This website:
+[anthonyhobday.com/sideprojects/saferules](https://anthonyhobday.com/sideprojects/saferules/)
+contains several safe rules to follow. If you're unsure of your design go
+through the list. Do not break them without judgement.
+
+### Documentation and Tests
+
+We know documentation and tests are boring, but they're important and we need
+you to add them for large changes.
+
+- **Documentation**: If the feature being added requires an explanation then
+  [documentation](https://docs.frappebooks.com/) should be updated in the
+  [frappe/books_docs](https://github.com/frappe/books_docs) repository.
+  _Add a link to the documentation PR in your feature PR._
+- **Tests**: If your features alters business logic then tests should be added.
+
+## Writing Tests
+
+You should write tests. If your features alter business logic and there are no
+tests then it is imperative to write tests.
+
+Here are a few rules of thumb to ensure that the tests you're writing are meaningful:
+
+- **Test values that should have changed against expected change.** If values
+  after an operation are not as expected, the tests should fail.
+- **Test values that shouldn’t have changed.** If values which shouldn’t have
+  changed also change, the test should fail.
+- **Don’t alter previously written tests,** unless they’re failing due to changes
+  in implementation.
+- **Don’t write tests for code that has already been tested,** unless you have
+  reason to believe that they could have changed.
+- **Manually test your changes using the UI atleast once**.
+- Don’t write tests for the sake of writing tests.
+- Don’t write tests just cause you aren’t sure how something executes.
+- Write tests cause you want to ensure that something continues to execute in
+  the way you intend for it to be executed.
+- Write tests cause manually clicking through the UI to check your changes is
+  time-consuming and not feasibly repeatable.
+- Write tests to catch unaccounted-for edge cases, then write code to account
+  for those edge cases.
