acme.sh --issue --dns dns_nsone -d example.com -d www.example.com
```
+## 27. Use DuckDNS.org API
+
+```
+export DuckDNS_Token="aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee"
+```
+
+Please note that since DuckDNS uses StartSSL as their cert provider, thus
+--insecure must be used when issuing certs:
+```
+acme.sh --insecure --issue --dns dns_duckdns -d mydomain.duckdns.org
+```
+
+Also, DuckDNS uses the domain name as username for recording changing, so the
+account file will always store the lastly used domain name.
+
+For issues, please report to https://github.com/raidenii/acme.sh/issues.
+
+## 28. Use Name.com API
+
+```
+export Namecom_Username="testuser"
+export Namecom_Token="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
+```
+
+And now you can issue certs with:
+```
+acme.sh --issue --dns dns_namecom -d example.com -d www.example.com
+```
+
+For issues, please report to https://github.com/raidenii/acme.sh/issues.

# Use custom API
If your API is not supported yet, you can write your own DNS API.
