# Installation

First of all, we need to install *bottle*. Write the following command in the terminal:
<pre>
pip install bottle
</pre>


# Code
In this code, we run the router on the specific host and port address. 
* The code starts by running the application using this command, 

   `app = bottle.default_app()`.

* The user writes the Response which they want to be viewed on the screen. Command:
`return Response()`.

* Write your string within the brackets of `Response()`. 

import os
import bottle
# import the following features from bottle
from bottle import route, run, Response

app = bottle.default_app()

@route('/')
def index():
    # Text within response is showed on the localhost
    return Response("Welcome to my bottle. Hello user.")

if __name__ == '__main__':
    port = int(os.environ.get('PORT', 5000))
    run(host='127.0.0.1', port=port, debug=True)

Open a web browser after executing $main.py$. You should be able to connect to `http://localhost:5000/` and see your application running!

Tada!
