+
+**A:** The steps for a production JAR are:
+
+- Open a command line, as Administrator
+
+- Build front-end (Angular)
+
+```bash
+npm install
+npm run build
+```
+
+- OR:Build and package JAR
+
+```bash
+mvnw -Pprod clean verify
+```
+
+- OR:Build and package JAR WITHOUT tests
+
+```bash
+mvnw -Pprod clean verify -DskipTests -Dmaven.test.skip=true
+```
+
+---
+
+**B:** The result is a JAR generated in : target/
+
+**C:** Things to validate
+
+- In target/classes a static/ must exist, after the "Build front-end (Angular)"
+- Check for BOOT-INF/classes/static dir in the generated JAR file
