1. Install Aspose.PUB for .NET and Aspose.PDF for .NET packages from NuGet.org
2. Reference four required namespaces to make the code work
3. Set license for both APIs separately by using SetLicense method
4. Create a parser for PUB file using PubFactory class
5. Load parsed PUB file into a Document object
