+# Setup Guide
+
+This guide will provide a step-by-step guide to make your machine ready to run Python with basic packages to get you started with machine learing.
+
+## Installing Python
+
+[Download PyCharm](https://www.jetbrains.com/pycharm/download/) (community version). It is one of the widely used IDE for Python and would make coding easier.
+
+Install [HomeBrew](https://brew.sh/) a package manager for Mac OS by running the following commands in the terminal.
+```bash
+xcode-select --install
+```
+```bash
+ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
+```
+
+Ensure Brew is correctly installed by running the following command.
+
+```bash
+brew doctor
+```
+
+Install Python 3.7 by running the following command.
+
+```bash
+brew install python3
+```
+
+After the installation check the version of the python and also its installation directory.
+
+```bash
+python3 --version
+which python3
+```
+
+The ouput of the directory should be somethhing like "/usr/local/bin/python3.7" or "/Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7"
+
+## Getting Started
+
+1. Start a new project in PyCharm. And push the dropdown of "Project Interpreter".
+2. Choose the option of "New environment using Virtualenv" and check that the version of the "Base interpreter" is Python3.7. Check your project directory and click "Create". [Virtualenv](https://www.pythonforbeginners.com/basics/how-to-use-python-virtualenv) allows us to have a seprate environment for each project which allows for smooth development.
+3. Create a new Python file either from the File menu or by right-clicking the project folder in the left widget.
+4. Let's run a simple code to understand how to run and view output.
+```python
+if __name__ == '__main__':
+	a = "This is a string."
+	b = 10
+	c = 55
+	result = b + c
+	print ("Hello World")
+	print ("The sum of two numbers: {}".format(result))
+```
+5. To run the above program either click the small green triangle besides the "if \_\_name\_\_ == '\_\_main\_\_':" or run the program from the Run menu.
+6. Feel free to explore some of the basic Python tutorials by clicking [here](https://www.datacamp.com/courses/intro-to-python-for-data-science).
+
+
+## Solving our first ML Problem
+We are gonna work on our first dataset by using simple [linear regression](http://onlinestatbook.com/2/regression/intro.html). We would be using a fairly small dataset for our problem called [Auto MPG](https://archive.ics.uci.edu/ml/datasets/auto+mpg).
