+This is a simple Client Updater for [DtDNS.com](http://dtdns.com).  
+
+Install the dependencies with : `npm install`  
+Launch it with : `node index.js`  
+With the `-v` argument it logs everything.  
+
+The first time the program launches, a `config.json` file will be created, you'll have to configure your DtDNS credentials and the update delay.  
+In ip, leave `""` to point to the current ip.  
+
+See [DtDNS api info](https://www.dtdns.com/dtsite/updatespec) for more info.
