Modules
=======

This guide documents all the necessary information needed to use the modules in the **CEAMSModules** package.
Modules are the building blocks of Snooz processes. Each module performs
a specific operation on signals, events, files, or parameters.

Modules are grouped by category as they appear in the Snooz Module Library.
Select a category below to browse module documentation.

How to use modules
------------------

1. In Snooz, go to **Dev Tools -> New process**.
2. Open the **Module Library** and enable the **CEAMSModules** package if needed.
3. Drag modules from a category onto the process canvas.
4. Connect module inputs and outputs to define your analysis pipeline.
5. Configure each module via its **Settings** tab and run the process.

For a hands-on introduction to processes and modules, see :doc:`/dev_guide/explore_ex`.
