Since SkeekS CMS itself and a number of third-party libraries are outside of your project, they need to be connected to the project as third-party libraries. Connect to your project a library of used vendors. This is necessary for your IDE to tell you the methods of the classes used. This will greatly speed up the development process.

The specificity of the SkeekS CMS project (and most modern projects) is that the project (usually at the root, but not necessarily) has the / vendor folder, the code stored in it cannot be changed !

Therefore, the entire project can be downloaded and stored without this folder.
