-# pa-calculator
+# PA Calculator
+Der PA Calculator dient der Berechnung von Limiterwerten für PA-Anlagen, sowie einem Tool, welches eine Stapelverarbeitung von Lautheitsanalysen sowie einer Korrekturempfehlung durchführen kann.
 
+## Einrichten der Build-Umgebung
+
+1. Installation von QT Version > 6.4.2 mit QT Installation Framework
+2. (Auf Windows) Installation msvc2019 oder neuer
+3. Installation 7zip
+4. Umgebungsvariablen hinzufügen (Qt Binaries, 7-Zip, QtInstallerFramework)
+
+## Release einer neuen Version
+Zum Kompilieren einer neuen Version sind folgende Schritte zu beachten:
+
+Die neue Version vor Kompilierung in folgenden Dateien anpassen:
+* source/PA_Calculator.pro
+* installer/config/config_xxx.xml
+* installer/packages/com.dkmtech.pacalculator/meta/package.xml
+Im Release-Modus Projekt kompilieren. 
+Im Anschluss Datei installer/createInstaller_xxx ausführen -> setup.exe
