+# EchoBot
+
+Bot Framework v4 echo bot sample.
+
+This bot has been created using [Bot Framework](https://dev.botframework.com), it shows how to create a simple bot that accepts input from the user and echoes it back.
+
+## Running the sample
+- Clone the repository
+```bash
+git clone https://github.com/Microsoft/botbuilder-python.git
+```
+- Activate your desired virtual environment
+- Bring up a terminal, navigate to `botbuilder-python\samples\02.echo-bot` folder
+- In the terminal, type `pip install -r requirements.txt`
+- In the terminal, type `python app.py`
+
+## Testing the bot using Bot Framework Emulator
+[Microsoft Bot Framework Emulator](https://github.com/microsoft/botframework-emulator) is a desktop application that allows bot developers to test and debug their bots on localhost or running remotely through a tunnel.
+
+- Install the Bot Framework emulator from [here](https://github.com/Microsoft/BotFramework-Emulator/releases)
+
+### Connect to bot using Bot Framework Emulator
+- Launch Bot Framework Emulator
+- Paste this URL in the emulator window - http://localhost:3978/api/messages
+
