+# Chat Simulator Project
+
+## What the project does
+This is a simple command-line chatbot built in Python. It responds to basic greetings, tells the time and date, and can exit the chat on command.
+
+## How to run
+1. Run the Python script:
+
+
+
+git checkout -b yaswanth-chat-simulator
+
+
+
+git add week1_projects/yaswanthkumarch/chat_simulator/
+git commit -m "Yaswanth – Chat Simulator Project"
+git push origin yaswanth-chat-simulator
+
+
+
+This pull request adds a simple command-line Chat Simulator built in Python.
+
+Features include:
+- Greeting the user
+- Responding to basic questions such as "What's your name?" and "What's the time?"
+- Responding differently based on keywords in user input
+- Allowing the user to exit the chat by typing keywords like "bye" or "exit"
+- Keeping a conversation history stored in a list
+
+The project demonstrates the use of Python syntax, conditional statements, loops, and basic CLI interaction.
+
+Looking forward to feedback and suggestions. Thank you!
