+# Hints
+
+## 1. Create the Alien Class
+
+- Remember that `object methods` are always passed `self` as the first parameter.
+- Remember the double underscores on _both_ sides of `__init__()`.
+- Instance variables are unique to the `class` instance (_object_) that possesses them.
+- Class variables are the same across all instances of a `class`.
+
+## 2. The `hit` Method
+
+- Remember that `object methods` are always passed `self` as the first parameter.
+- You can choose to allow the Alien's health to fall below zero, or require that it does not.
+
+## 3. The `is_alive` Method
+
+- Remember that `object methods` are always passed `self` as the first parameter.
+- 0 may not be the only 'dead' condition, depending on how `hit()` is implemented.
+
+## 4. The `teleport` Method
+
+- Remember that `object methods` are always passed `self` as the first parameter.
+- Instance attributes can be updated from a method by using `self.<attribute>` = `<new attribute value>`.
+
+## 5. The `collision_detection` Method
+
+- Remember that `object methods` are always passed `self` as the first parameter.
+- This method seems like an excellent place to use some kind of placeholder…
+
+## 6. Alien Counter
+
+- Class attributes are the same across all instances of a `class`.
+- Ideally, this counter would increment whenever someone _made an new Alien_.
+- Class attributes can be changed from an instance method by using the _class name_:  `Alien.<class attribute name>`.
+- `__init__()` is considered an instance method since it _initializes a new object_.
+
+## 7. Object Creation
+
+- A `tuple` would be a _single_ parameter.
+- The Alien constructor takes _2 parameters_.
+- Unpacking what is _inside_ the tuple would yield two parameters.
+- The standalone function is outside of the `class`
