-# Duke project template
-
-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
-
-Prerequisites: JDK 17, update Intellij to the most recent version.
-
-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 17** (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
- ____ _
- | _ \ _ _| | _____
- | | | | | | | |/ / _ \
- | |_| | |_| | < __/
- |____/ \__,_|_|\_\___|

+# John Cena Todo List Application :tada:
+
+Welcome to the **John Cena** Todo List application! This app helps you manage your tasks efficiently with commands like `todo`, `deadline`, `event`, `find`, `after`, and more. It automatically saves your tasks, ensuring you never lose track of your to-dos.
+
+## 🚀 Features
+
+- **Add Tasks**: Create `todo`, `deadline`, `event`, and `after` tasks.
+- **Manage Tasks**: Mark, unmark, and delete tasks.
+- **Search Tasks**: Find tasks by keyword.
+- **View Tasks by Date**: List tasks occurring on a specific date.
+- **Automatic Saving**: Tasks are saved automatically to prevent data loss.
+- **User-Friendly GUI**: Intuitive interface for easy interaction.
+
+## 🛠Installation
+
+Follow these simple steps to set up the **John Cena** Todo List application:
+
+1. **Download the JAR file** from the [Releases](https://github.com/ishan-agarwal-05/ip/releases) section of this repository.
+
+2. **Run the application** using the following command:
+
+ ```bash
+ java -jar johncena.jar
+ ```
+
+---
+
+## 📚 Acknowledgements
+
+- **Java**: The primary programming language used for this project.
+- **IntelliJ IDEA**: The IDE used for development.
+- **GitHub**: For hosting the project repository.
+- **OpenAI**: For providing AI assistance.
+- **JavaFX**: For the GUI framework.
+- **JUnit 5**: For testing the application.
+- **Gradle**: For building the project.
+- **Github Copilot**: For generating code snippets and javadoc comments.
+- **AB3 User Guide and blackpanther9229**: For the template of user guide.
+
+
+## 🤖 Special Acknowledgment for GitHub Copilot
+
+Throughout the development of this project, GitHub Copilot was used for code autofill and suggestions.
+
+For example:
+- The `Deadline` class was coded manually, but the `Event` class has similarities due to Copilot's autofill suggestions.
+- Many command classes, such as `TodoCommand`, `DeadlineCommand`, and `EventCommand`, were generated with significant help from Copilot.
+
+This extensive use of AI assistance has helped streamline the development process, but it also means that large segments of the code are AI-generated and might resemble code from other projects.

+
+## John Cena Task Manager Supports the Following Features:
+
+> [!NOTE]
+> Notes about the syntax format:
+> - Words in single quotation mark `''` are the parameters to be supplied by the user.
+ The parameters should follow the guide in the single quotation mark.
+ e.g. in `Todo 'Description'`, `'Description'` is a parameter which can be used as `Todo Sleep`.
+> - Extra arguments in most of the command types will be interpreted as a wrong format error.
+> - The date and time format should be in `yyyy-mm-dd HHmm` format.
+> - The commands are case-sensitive. e.g. `todo` will work, but `Todo` will not work.
+
+### 1. Adding a To-do task
+
+To add a To-do to the storage, use the following format:
+
+`todo 'Description'`

+* The task will be removed from the list.
+
+Example:
+`delete 2`
+
+Response:
+```
+ Noted. I've removed this task. Now, you can't see me and neither can you see that task:
+ [D] [ ] CS2100 (by: 2024-09-25 1600)
+ Now you have 4 tasks in the list.
+```
+> [!NOTE]
+> After a task is deleted, the remaining tasks will be automatically renumbered.
+> E.g: task list has 3 tasks with index 1, 2, 3, after deleting task 2, old task 3 will become new task 2.

-## Feature ABC
+The program will close.
-// Feature details
+--------------------------------------------------------------------------------------------------------------------
+## Known Issues
+1. **Command Overwriting**: If users attempt to add a task with the same description as an existing one, the app does not prevent duplicates. Users should manage their tasks accordingly.
+2. **Not Case-Sensitive**: The app is not case-sensitive, so users should ensure they input commands in lowercase.
+3. **Date and Time Format**: The app only accepts dates and times in the `yyyy-mm-dd HHmm` format. Users should ensure they input dates and times correctly.

+# Gradle start up script for POSIX generated by Gradle.
+#
+# Important for running:
+#
+# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+# noncompliant, but you have some other compliant shell such as ksh or
+# bash, then to run this script, type that shell name before the whole
+# command line, like:
+#
+# ksh Gradle
+#
+# Busybox and similar reduced shells will NOT work, because this script
+# requires all of these POSIX shell features:
+# * functions;
+# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+# * compound commands having a testable exit status, especially «case»;
+# * various built-in commands including «command», «set», and «ulimit».
+#
+# Important for patching:
+#
+# (2) This script targets any POSIX shell, so it avoids extensions provided
+# by Bash, Ksh, etc; in particular arrays are avoided.
+#
+# The "traditional" practice of packing multiple parameters into a
+# space-separated string is a well documented source of bugs and security
+# problems, so this is (mostly) avoided, by progressively accumulating
+# options in "$@", and eventually passing that to Java.
+#
+# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+# see the in-line comments for details.
+#
+# There are tweaks for specific operating systems such as AIX, CygWin,
+# Darwin, MinGW, and NonStop.
+#
+# (3) This script is generated from the Groovy template
+# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+# within the Gradle project.
+#
