# Um TrustBridge zu installieren:
# 1. Prüfen Sie, ob Sie dieser Datei genügend vertrauen, um ihr die
#    Kontrolle über diesen Rechner zu übergeben. Beispielsweise
#    durch Vergleich mit einer starken Prüfsumme aus einer zweiten,
#    unabhängigen Quelle.
# 2. Öffnen Sie eine Kommandozeile (Anwendung "Terminal").
# 3. Wechseln Sie in das Verzeichnis, in dem diese Datei gespeichert
#    ist (z.B. per Kommandozeile mit: "cd ~/Schreibtisch").
# 4. Starten Sie die Anwendung auf der Kommandozeile, beispielsweise
#    als Installation nur für den aktuellen Nutzer, indem Sie
#    eingeben:
#    	bash TrustBridge-1.0.0-amd64.sh
#    Tipp: Die Tab-Taste nach dem "Tr" ergänzt oft den ganzen Namen.
#
# Übrigens, wir konnten kein übliches .deb-Paket verwenden, da
# TrustBridge Ihnen auch die Installation als reiner Nutzer ohne
# Admin-Rechte ermöglichen soll.
#
#
# To install TrustBridge:
# 1. Verify that you trust this specific file far enough, that you
#    are willing to hand over the control of your computer to it. For
#    example compare a strong checksum of the file to one from a
#    second, independent source.
# 2. Open a command line (application "Terminal").
# 3. Change your working directory to where this file is stored.
#    (e.g. type "cd ~/Desktop" on your command line).
# 4. Start the installation on the command line, e.g. for the current
#    user only by typing something like:
#       bash TrustBridge-1.0.0-amd64.sh
#    Hint: If you press the tab-key after "Tr" it may complete the
#    filename.
#
# By the way: We could not have used a .deb package, because the
# installation must also work without without adminstrator
# priviledges.
