+# The secret tresor application frontend
+
+## Technik
+
+- basiert auf React
+
+## Umgebungsvariablen
+
+- In der **Datei .env** sind die von der Applikation **verwendeten Umgebungsvariablen** deklariert.
+- Falls die Umgebungsvariablen _aussen_ nicht gesetzt sind, wird ein Default-Wert verwendet.
+
+## Hinweise zur Anwendung der Applikation
+
+- Die Applikation ist für den Unterricht gedacht.
+- Die vorliegende Version hat keine Security implementiert.
+- So spielt das Passwort (noch) keine Rolle.
+
+- Wenn die Applikation gestartet ist, kann man mit</br>
+  _Admin->All user_</br>
+  Vom Backend das Verzeichnis aller User abrufen.
+
+- Mit</br>
+  _User->Register_</br>
+  Kein ein neuer User via Backend gespeichert werden
+- Danach ist ein Login des Users notwendig.</br>
+  _User->Login_ mit Email und Passwort</br>
+  Diese Login-Daten sind für die _Secrets_ Funktionen notwendig.
+- Es können drei unterschiedliche Secrets gespeicher werden.
+- Und es können die eigenen Secrets abgerufen werden.
+
+## Build image
+
+see Dockerfile
+
+```Bash
+docker build -t tresorfrontendimg .
+```
+
+## Start container local
+
+```Bash
+docker run -p 80:80 --name tresorfrontend tresorfrontendimg
