Embedding some Appian features within a Sharepoint interface

#Integration Sharepoint

We are trying to embed some Appian features within Sharepoint interface. I found a document in Appian on how to achieve that, but the document suggest that for installing the web part solution file we need to unzip the appian-sharepoint2013-X.y.z.zip in sharepoint server. Please suggest from where we can download this zip file?
