-// Product intro goes here
+- **Adds Tasks:** Automatically adds tasks to a file.
+- **Mark Tasks as Done:** You can mark tasks as completed.
+- **Delete Tasks:** Allows you to remove tasks from the list.
+- **List Tasks:** Displays all tasks in your list with their current status.
-## Adding deadlines
+## Task Types
-// Describe the action and its outcome.
+Opus supports three types of tasks:
+- **Deadlines:** Tasks that need to be completed by a specific date.
+- **Events:** Tasks that span a specific time period.
+- **ToDos:** Simple tasks without deadlines or timeframes.
-// Give examples of usage
+## Using Opus
-Example: `keyword (optional arguments)`
-// A description of the expected outcome goes here
+### Feature 1: Adding Tasks
+To add a Task to the List, you have to specify what task you are adding. The task could be a Deadline, an Event, or a ToDo.
+
+#### Adding a Deadline
+
+###### Format of input : `deadline /by `
+###### Example Input: `deadline return book /by Sunday`
+
+###### Expected output:
+```
+Got it. I've added this task:
+ [D][ ] return book (by: Sunday)
+Now you have 1 task in the list.
+```
+
+#### Adding an Event
+
+###### Format of input : `event /from /to `
+###### Example input: `event project meeting /from Mon 2pm /to 4pm`
+
+###### Expected output:
+```
+Got it. I've added this task:
+ [E][ ] project meeting (from: Mon 2pm to: 4pm)
+ Now you have 2 tasks in the list.
+```
+#### Adding a ToDo
+
+###### Format of input : `todo `
+###### Example input: `todo submit report`
+
+###### Expected output:
```
-expected output
+Got it. I've added this task:

+```
+
+
+### Feature 4: Listing Tasks
-## Feature XYZ
+Use the `list` command to list all Tasks.
+###### Format of input : `list`
+
+###### Example : `list`
+###### Expected output:
+```

+# 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.
+#
+# You can find Gradle at https://github.com/gradle/gradle/.
