+## Configuring
+Default configuration file is located in `config/` folder.
+
+To change the default configuration values, create local files that override the parameters you need to change:
+* Create a new `environment.dev.js` file in `config/` for `devel` environment;
+* Create a new `environment.prod.js` file in `config/` for `production` environment;
+ 
+To use the configuration parameters in your component:
+```bash
+import { GlobalConfig } from "../config";
+```
 
 ## Running the app
 After you have installed all dependencies you can now run the app. Run `npm run watch:dev` to start a local server which will watch for changes, rebuild the code, and reload the server for you. You can visit it at `http://localhost:3000`.
