+glassfish7/bin/asadmin start-domain
+
+# deploy app on it
+glassfish7/bin/asadmin deploy target/shop-1.0-SNAPSHOT.war
+```
+
+we can browse server at [http://localhost:8080/shop-1.0-SNAPSHOT/api/items](http://localhost:8080/shop-1.0-SNAPSHOT/api/items)
+
+## Start client
+```bash
+# cd to clients project directory
+cd client
+
+# compile and run project
+mvn clean compile exec:java
+```
+
+The client class handles HTTP operations, while the Delegator class handles user interaction, input validation, and adapts the input into the correct format. Delegator then calls the appropriate Client methods, acting as a proxy in a liberal sense.
+
+## Ending the program
+
+Clent program can be ended by typing `done` or `exit` in the interactive terminal
+
+Glassfish can be stoped using the following command in terminal
+```bash
+# first check which domains are running
+glassfish7/bin/asadmin list-domains
+# you will get somehing like the below lines
+#      domain1 running
+#      Command list-domains executed successfully.
+# we have domain1 running. so we stop it with
+glassfish7/bin/asadmin stop-domain domain1
+```

+## DONE
