Welcome to the WD community wiki.

In the near future, you'll find a lot of info here about WD MyCloud NAS devices. Only OS3 based products are handled here. Most of the information used to be available on developer.mycloud.com.

The goal is to create an open source environment to build apps for the whole OS3 range in similar fashion as they do on SynoCommunity.
