+# Interfaces
+Interfaces are a way to describe properties and methods on an object.
+
+## Simple example
+Interfaces can have both properties and methods.
+
+```BrighterScript
+interface Person
+    name as string
+    function getName() as string
+end interface
+
+sub test(bob as Person)
+    print bob.name, bob.getName()
+end sub
+```
+
+transpiles to
+
+```BrightScript
+sub test(bob as object)
+    print bob.name, bob.getName()
+end sub
+```
+
+## Use in functions
+Interfaces can be used as function parameter types and return types. These types will be converted into `dynamic` when the project is transpiled.
+```brighterscript
+interface Dog
+    name as string
+    function walk()
+end interface
+
+sub walkThePuppy(puppy as Dog) as Dog
+    puppy.walk()
+    return puppy
+end sub
+```

+
+```BrightScript
+sub walkThePuppy(puppy as object) as object
+    puppy.walk()
+    return puppy
+end sub
+```
+</details>
+
+## Namespaces
+Interfaces can also be defined inside namespaces
+
+```BrighterScript
+namespace humanoids
+    interface Person
+        name as string
+        function getName() as string
+    end interface
+end namespace
+
+sub test(bob as humanoids.Person)
+    print bob.name, bob.getName()
+end sub
+```
+
+transpiles to
+
+```BrightScript
+sub test(bob as object)
+    print bob.name, bob.getName()
+end sub
+```
+
+## Advanced types
+Interface member types can be defined as any valid brighterscript type, and even reference themselves.
+```brighterscript
+interface Dog
+    owner as Human
+end interface
+
+interface Human
+    pet as Dog
+    mother as Human
+end interface
+```
