-# Duke project template
+# Welcome to Duke
+## A Personal Assistant Chatbot that helps a person to keep track of various tasks
-This is a project template for a greenfield Java project. It's named after the Java mascot _Duke_. Given below are instructions on how to use it.
+
-## Setting up in Intellij
+> User interface example
-Prerequisites: JDK 11, update Intellij to the most recent version.
+You can view the user guide [here](https://zhongli5712.github.io/ip/).
-1. Open Intellij (if you are not in the welcome screen, click `File` > `Close Project` to close the existing project first)
-1. Open the project into Intellij as follows:
- 1. Click `Open`.
- 1. Select the project directory, and click `OK`.
- 1. If there are any further prompts, accept the defaults.
-1. Configure the project to use **JDK 11** (not other versions) as explained in [here](https://www.jetbrains.com/help/idea/sdk.html#set-up-jdk).
- In the same dialog, set the **Project language level** field to the `SDK default` option.
-3. After that, locate the `src/main/java/Duke.java` file, right-click it, and choose `Run Duke.main()` (if the code editor is showing compile errors, try restarting the IDE). If the setup is correct, you should see something like the below as the output:
- ```
- Hello from
- ____ _
- | _ \ _ _| | _____
- | | | | | | | |/ / _ \
- | |_| | |_| | < __/
- |____/ \__,_|_|\_\___|
- ```
+You can download jar file in the latest release and run the file by command ```java -jar duke.jar```.
+
+## Acknowledgement
+This project is referencing resources on the Duke project created by the [SE-EDU Initiative](https://se-education.org/)
