 ## DNS Records
 
 Note: In this documentation:
-- `example.com` is your domain name
-- `auth.example.com` is the subdomain you want to use for acme-dns
+- `auth.example.org` is the hostname of the acme-dns server
+- acme-dns will serve `*.auth.example.org` records
 - `198.51.100.1` is the **public** IP address of the system running acme-dns  
 
 These values should be changed based on your environment.
 
 You will need to add some DNS records on your domain's regular DNS server:
-- `NS` record for `auth.example.com` pointing to `auth.example.com` (this means, that `auth.example.com` is responsible for any `*.auth.example.com` records)
-- `A` record for `auth.example.com` pointing to `198.51.100.1`
+- `NS` record for `auth.example.org` pointing to `auth.example.org` (this means, that `auth.example.org` is responsible for any `*.auth.example.org` records)
+- `A` record for `auth.example.org` pointing to `198.51.100.1`
 - If using IPv6, an `AAAA` record pointing to the IPv6 address.
 - Each domain you will be authenticating will need a `_acme-challenge` `CNAME` subdomain added. The [client](README.md#clients) you use will explain how to do this.
 
 ## Testing It Out
 
 You may want to test that acme-dns is working before using it for real queries.
 
-1) Confirm that DNS lookups for the acme-dns subdomain works as expected: `dig auth.example.com`.

 2) Call the `/register` API endpoint to register a test domain:
 ```
-$ curl -X POST http://auth.example.com/register

 3) Call the `/update` API endpoint to set a test TXT record. Pass the `username`, `password` and `subdomain` received from the `register` call performed above:

 Note: The `txt` field must be exactly 43 characters long, otherwise acme-dns will reject it
 
 4) Perform a DNS lookup to the test subdomain to confirm that everything is working properly:
