Es gibt einen NIG-Root-Ordner. In diesem liegen alle Dateien die zur Einrichtung benötigt werden. In diesem werden auch alle NIG-Environments gespeichert. Alle NIGs verwenden persistenten Speicher. In dem NIG-Ordner befinden sich mehrere Ordner und das Installationsscript. Die Ordnerstruktur:

• base-nginx
• base-nig
• newNIG.sh
• nig-environments

nig.sh
