## Installation guide
Make sure you have installed node.js. If you have not, install it via https://nodejs.org/en/ (version 14.17.0 is good).
When installed, follow the installation wizard to setup node.js. Install the npm (package manager), if asked.
Open the node.js command prompt and type
```
npm install -g expo-cli
```
When done, go to the path on your computer the code from GitLab is on, e.g. C:\Users\{yourname}\documents\gl-proj\TraCloSo by typing:
```
cd {your path}
```
Open it by typing
```
npm start
```
To preview the project you need to download Expo Client App on your smartphone. Depending on the phone you have you can do this on the App Store or the Google Play Store.
Once you have the Expo Client App installed scan the QR Code that you saw when you ran npm start on the terminal. You will have to wait a couple of minutes at first while your project bundles and loads for the first time. After it has completed loading you will see a short message in the center of the screen.
In case you want to use a simulator, download Xcode for IOS and Android Studio for Android
If you are using Windows as an operating system you will not be able to download Xcode (due to Appleās restrictions). Therefore, you need a physical IOS device
Open the folder TraCloSo in the editor of your choice (e.g. Sublime Text or Visual Code), and open App.js. There you see the text. You can edit it, save it, and the new text will be displayed on your screen!
