Packages
The Sigma App is a package (a single file) containing:

A manifest file
Installation files

The manifest file describes the App ID, version and contents. Basically the file is a ZIP file, containing at least a file called install.xml, which is a manifest file describing everything else in the package. The extension of the file must be .sigmapackage (instead of .zip).
Package files can be manually installed in Sigma by:

Specifying the filename on the Sigma command line.
Dragging a package file onto Sigma.
Double-clicking on a package file in the Windows Shell.

Installation actions are logged to a file named install.log located in the destination folder.
A typical way to structure the package (zip) file is:

root folder
 |--install.xml
 --source
    |--my pricebook.sli
    |--my template.sit
    --myapp.sigmabundle

Below is an example install.xml file. Complete documentation is found here:&nbsp;Package API

&lt;sigma.package.manifest&gt;
    &lt;id&gt;MyAppId&lt;/id&gt;
    &lt;name&gt;My App Name&lt;/name&gt;
    &lt;version&gt;1.1.0.0&lt;/version&gt;

            &lt;replace&gt;yes&lt;/replace&gt; &lt;!-- Always replace --&gt;
