 These live inside the `Samples~` folder as required by the [Package Manager specification](https://docs.unity3d.com/Manual/cus-samples.html). However, the Unity Editor will ignore any folders/files with a '~' character in their name and will not create a `.meta` file for them or import them. In order to facilitate our development, we create a symbolic link named `Samples` that points to the `Samples~` folder - allowing us to see and interact with our Samples and Setup scripts.
 
+## Environments
+
+Sequence generally uses two environments for our backend services: dev and production. By default, the SDK will always use production.
+
+However, during development, it is occasionally useful to send requests against the dev environment. To do this, you'll first need to have access to the dev version of the Sequence Builder; here, you can generate credentials (API key, WaaS config key, etc.) for your SequenceConfig. This time however, you'll place your configuration in a SequenceConfig instance titled 'SequenceDevConfig' in a `Resources` folder.
+
+In order to use the dev environment, you'll want to set the appropriate scripting define symbol for your service in your Player Settings.

+- `SEQUENCE_DEV_WAAS` - the WaaS/EmbeddedWallet service

 ## Assembly Overview
 
 The SDK is split into a number of assemblies with different purposes. Each assembly also has a Test assembly or assembly reference containing tests - this way, our tests aren't included in builds.

 ## Component Overview - Ethereum Client (SequenceEthereum)
 The SDK is broken into a number of components with different responsibilities. This section will give an overview of some of the most important components for users and their intended purposes.
