-### Sandbox Environment
-
-We highly recommend testing against our [sandbox environment](https://developer.dnsimple.com/sandbox/) before using our
-production environment. This will allow you to avoid real purchases, live charges on your credit card, and reduce the
-chance of your running up against rate limits.
-
-The client supports both the production and sandbox environment. To switch to sandbox pass the sandbox API host using
-the `base_url` option when you construct the client:
-
-```python
-from dnsimple import Client
-
-client = Client(base_url='https://api.sandbox.dnsimple.com', access_token="a1b2c3")
-```
-
-You can also set the sandbox environment like so:
-
-```python
-from dnsimple import Client
-
-client = Client(sandbox=True, access_token='a1b2c3')
-```
-
-You will need to ensure that you are using an access token created in the sandbox environment.
-Production tokens will *not* work in the sandbox environment.

 For example, if you use `my-app`, the final header value will be `my-app dnsimple-python/0.1.0` (note that it will vary depending on the client version).
