 First you need to create/obtain API credentials on your Infoblox appliance.
- 
+
 ```
 export Infoblox_Creds="username:password"
 export Infoblox_Server="ip or fqdn of infoblox appliance"
 ```
-

 Ok, let's issue a cert now:
 ```
 acme.sh --issue --dns dns_infoblox -d example.com -d www.example.com
 ```
- 
+
 Note: This script will automatically create and delete the ephemeral txt record.
 The `Infoblox_Creds` and `Infoblox_Server` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

+## 25. Use DNSimple API
+
+First you need to login to your DNSimple account and generate a new oauth token.
+
+https://dnsimple.com/a/{your account id}/account/access_tokens
+
+Note that this is an _account_ token and not a user token. The account token is
+needed to infer the `account_id` used in requests. A user token will not be able
+to determine the correct account to use.
+
+```
+export DNSimple_OAUTH_TOKEN="sdfsdfsdfljlbjkljlkjsdfoiwje"
+```
+
+To issue the cert just specify the `dns_dnsimple` API.
+
+```
+acme.sh --issue --dns dns_dnsimple -d example.com
+```
+
+The `DNSimple_OAUTH_TOKEN` will be saved in `~/.acme.sh/account.conf` and will
+be reused when needed.
+
+If you have any issues with this integration please report them to
