Setting up a HPGeochemistry project is detailed in the general HPx manual. To work with modules, a managed project is required. the online HPx manual  provides information on how to make a managed project - See Define a new managed project.

In this manual, we illustrate how to to create a managed project with an active cement module. If there is an update of the module, the same procedure can be used to import the module update in your projects. However, some information in an already existing project will not be updated, in particular the global variable input table. Other aspects are updates, such as tables with data and external scripts (see further). This means that a calculated existing simulation  may not be consistent with the updated module. The tutorial updating the cement module shows how to update a module.
