+# NameSilo
+
+[![NameSilo Website](../readme/namesilo.jpg)](https://www.namesilo.com)
+
+## Configuration
+
+### Example
+
+```json
+{
+  "settings": [
+    {
+      "provider": "namesilo",
+      "domain": "sub.example.com",
+      "key": "71dZaE8c2Aa926Ca2E8c1",
+      "ttl": 7207,
+      "ip_version": "ipv4"
+    }
+  ]
+}
+```
+
+### Compulsory parameters
+
+- `"domain"` is the domain to update. It can be `example.com` (root domain), `sub.example.com` (subdomain of `example.com`) or `*.example.com` for the wildcard.
+- `"key"` is the NameSilo API Key obtained using the domain setup instructions below. For example: `71dZaE8c2Aa926Ca2E8c1`.
+
+### Optional parameters
+
+- `"ip_version"` can be `ipv4` (A records), or `ipv6` (AAAA records) or `ipv4 or ipv6` (update one of the two, depending on the public ip found). It defaults to `ipv4 or ipv6`.
+- `"ipv6_suffix"` is the IPv6 interface identifier suffix to use. It can be for example `0:0:0:0:72ad:8fbb:a54e:bedd/64`. If left empty, it defaults to no suffix and the raw public IPv6 address obtained is used in the record updating.
+- `"ttl"` is the record's Time to Live (TTL), which defaults to `7207` seconds. It must be numeric, less than `2592001`, and greater than or equal to `3600`. TTL values of `3603` or `7207` may be subject to NameSilo's [Automatic TTL Adjustments](https://www.namesilo.com/support/v2/articles/domain-manager/dns-manager#auto_ttl).
+
+## Domain setup
+
+1. Login to the [Namesilo API Manager](https://www.namesilo.com/account/api-manager) with your account credentials.
+1. Generate an API key. The generated API key will look similar to `71dZaE8c2Aa926Ca2E8c1`.
+    - (do _not_ check the "Generate key for read-only access" box)
+
+    [![Before NameSilo API Key](../readme/namesilo1.jpg)](https://www.namesilo.com/account/api-manager)
+    [![After NameSilo API Key](../readme/namesilo2.jpg)](https://www.namesilo.com/account/api-manager)
+
+## Testing
+
+1. Go to the [NameSilo Domain Manager](https://www.namesilo.com/account_domains.php).
+1. Choose "Manage DNS for this domain" (the globe icon) for the domain you wish to test.
+    [![Manage DNS for this domain](../readme/namesilo3.jpg)](https://www.namesilo.com/account_domains.php)
+
+1. Change the IP address of the host to `127.0.0.1`.
+1. Run the ddns-updater.
+1. Refresh the Namesilo webpage to check the update occurred.
