what is extensions fr?

CairnCMS Extensions is a collection of official add-ons for CairnCMS, a content management system hosted in its own separate repository. This repository is maintained directly by the CairnCMS project itself, rather than by outside contributors, so it holds the first party extensions that ship alongside the core platform. At the moment the collection is small. It contains one extension, called Live Preview, which lets someone editing content see a live preview of how an item will look on the actual website, shown in a split pane right next to the editing screen. The project structure is set up to hold many more extensions over time, each one published as its own package to npm under the cairncms scope. Installing any extension from this repository follows a common pattern: you can unpack the published npm package into your CairnCMS project's extensions folder, add it as a normal npm dependency, or include it when building a custom Docker image for deployment. Since each extension is published separately, every package has its own README with the specific installation steps, configuration options, and notes for whoever is running the site. The project keeps its contribution guidelines and security disclosure process in separate files, CONTRIBUTING.md and SECURITY.md, rather than folding that information into this main page. The whole repository is released under the GPL-3.0 license, which means anyone who builds on this code and distributes it must also share their changes under the same license terms. Because this README is quite short, there is not much more detail here about how CairnCMS itself works or how deeply these extensions integrate with it. Anyone wanting the full picture would need to look at the main CairnCMS repository and the individual extension packages themselves.
