 # Features
 
+All **`MultiTest`** features a listed in the following table. The **"Default implementation"**
+column indicates whether the feature has a default implementation in **`MultiTest`** that simulates
+the functionality of the real blockchain as closely as possible. In cases where **`MultiTest`** does
+not have a default implementation for the feature, users may provide their own, using `AppBuilder`'s
+function listed in **"AppBuilder constructor"** column. Names of **`MultiTest`** feature flags
+required to enable specific functionality are provided in the column **"Feature flag"**.
