+# Component checklist
+
+This checklist describes the process by which Material components are built.
+
+| ↓ Component \ Task → | [API review](#api-review) | [Minimize dependencies](#minimize-dependencies) | [Nullability](#nullability-annotations) |
+|:------------- |:-------------:|:-------------:|:-------------:|
+| SomeComponent  |  |  |  |
+
+## API review
+
+API reviews work like typical code reviews with the added constraint of only reviewing the
+component's **public APIs**.
+
+To initiate an API review, send a pull request that only includes the public APIs you wish to
+review.
+
+TODO(featherless): Flesh this out with some concrete examples of existing API reviews.
+
+## Minimize dependencies
+
+We generally recommend zero dependencies as a goal, but reasonable exceptions can be made.
+
+Avoid creating shared "Core" or "Utility" libraries. These wildcard libraries inevitably acquire
+dust and reduce the modularity of anything built atop of them.
+
+If your component does depend on such utilities, consider duplicating small functions within your
+component.
+
+## Nullability annotations
+
+Nullability annotations improve our API compatibility in Swift.
+
+1. **required** Add nullability annotations to every header of your component.
+
+> Note: Material components **explicitly** annotate all public APIs rather than use
+`NS_ASSUME_NONNULL_BEGIN`. This is an intentional deviation from Apple’s practice of using the
+`ASSUME` macros.
+
+The general annotation for id pointers is `nonnull`, `nullable` and `null_resetable`. They should be
+used in method parameters, return values and property annotations.
+
+`nonnull` - This pointer cannot be nil. This is commonly used for required method parameters or
+properties and return values that are guaranteed to exist.
+
+Consider the required URLString parameter in:
+
+    - (instancetype)[NSURL initWithString:(nonnull NSString *)URLString];
+
+`nullable` - This pointer may or may not be equal to nil.  This is commonly used for optional method
+parameters, properties that are optional or as return values for a method that may not succeed.
+
+Consider an NSDictionary returning nil when asked for a key:value pair that is doesn’t contain:
+
+    - (nullable id)[NSDictionary objectForKey:key];
+
+`null_resettable` - Used on properties that will always return a non-nil value, but you can reset
+the property to its default by setting it to nil.
+
+Consider UISwitch’s tintColor property:
+
+    @property(null_resettable, nonatomic, strong) UIColor *tintColor;
+
+`null_unspecified` - Indicates that you cannot make any guarantees to the state of this pointer. You
+probably shouldn’t be using this annotation.
+
+For plain C pointers, `__nullable` or `__nonnull` can be used.  To avoid conflicts with third-party
+libraries, Xcode 7 also introduced replacement  keywords `_Nullable` and `_Nonnull`.
+
+Once you add the first nullability annotation to any API in a file, Xcode will emit warnings for all
+other APIs in that file that must also be annotated.
+
+TODO(featherless): Add other steps.
