 This directory contains everything to build a deb package that bundles a Spring Boot app that starts a web server.
 
-The Spring Boot application has not been bundled with this. You need to build it seperately and put it in the correct directory (run build.sh for further details).
+  build.sh - This script builds the deb package.
+  create-new-project.sh - This script can be used to create a new deb package project similar to this project that uses a different name (than fs-spring-boot-kamal). Output will be placed inside 'out' directory.
+
+To create a new deb package project that uses 'mycompany-myapp' as the name, run the following command:
+
+  ./create-new-project.sh mycompany-myapp
+
+  The newly generated project files will be found inside the out directory.
 
 To build, run the following command:
 
   ./build.sh
 
+  Note that the Spring Boot application has not been bundled with this. You need to build it seperately and put it in the correct directory (run build.sh for further details).
+
 To install the build deb package run the following commands replacing the package.deb with the correct name of the deb file.
 
   cp package.deb /tmp
