This section of the documentation contains all the information for admins that want to create portals with the
Masterportal software.

## General Structure

The Masterportal is configured by a set of JSON files. These files are divided into two categories:

### Global configuration files

These files describe central information to be used by multiple portals:

* **[services.json](./Global-Config/services.json.md)**: lists all available layers
* **[rest-services.json](./Global-Config/rest-services.json.md)**: URLs to various external services
* **[style.json](./Global-Config/style.json.md)**: holds style definitions for vector layers

### Portal-specific configuration files

These files define the distinguishing features of an instance:

* **[config.js](./Portal-Config/config.js.md)**: Configuration of paths to further configuration files and services
* **[config.json](./Portal-Config/config.json.md)**: Configuration of portal appearance and available contents

The following figure schematically demonstrates the ensemble of files. Please mind that the files **index.html**, **[config.js](./Portal-Config/config.js.md)**, and **[config.json](./Portal-Config/config.json.md)** must be placed in the same path.
