+## Octokit Models
+
+These either represent the body of a GitHub API request or response.
+
+Request objects should be placed in the, you guessed it, _Request_ folder. Likewise Response objects should be placed
+in the _Response_ folder.
+
+Some models can be used for both requests and responses.
+
+### Request models
+
+The general design principle for request models are:
+
+1. They represent the body of a request.
+2. Properties that are _required_ by the API should be required by the model and passed in via the constructor.
+3. Required porperties should not have a setter since they will be set by the constructor.
+4. All other properties should have both a getter and setter.
+
+Note that Octokit.net automatically converts property name to the Ruby casing required by the GitHub API. Thus a
+property named `BreakingBad` would be passed as `breaking_bad`.
+
+### Response models
+
+The general design principle for response models are:
+
+1. They should be immutable. As such, properties have a `public` getter and `protected` setter.
+2. We want the properties to be read only, but also make it possible to mock the response from API methods.
+3. They must be easily serialized and deserialized.
+4. They need a default constructor as well as one that takes in every parameter.
+
+We're in the process of reconsidering this design as it's created a few problems for us. Namely that creating these
+objects in a unit test is a royal pain.
+
+### Notes
+
+There's a lot of confusion caused by the fact that the GitHub API returns GitHub resources as well as Git resources.
+For example, you can use the [Git Data API](https://developer.github.com/v3/git/) to directly manipulate Git objects
+such as a `commit`. At the same time, GitHub also has its own `commit` (represented by `GitHubCommit` in Octokit.net)
+that contains the GitHub information around the commit such as comments.
