# Building configuration file

Compiling your configuration into a `.mapeosettings` file is the final step for testing and using your configuration in Mapeo Mobile and Desktop.

Building a configuration can be done in two ways:

* [Via the command line](/complete-reference-guide/customization-options/custom-configurations/creating-custom-configurations/coding-configuration/building-configuration-file/preparing-computer.md)(with Node.js and **mapeo-settings-builder**)
* [Using GitHub Actions](/complete-reference-guide/customization-options/custom-configurations/creating-custom-configurations/coding-configuration/building-configuration-file/using-github-actions.md)
