-
-## Setup and Tutorial
-
-You will find the github part of this tutorial [here](https://github.com/Programming-Club-IAU/git-and-github)
-
-### 1. Setup
-
-#### 1.1: Install Python (not needed if you have a mac)
-
-- Download Python from [here](https://www.python.org/downloads/)
-- Install Python
-- Open a terminal and type `python --version` to check if Python is installed
-
-#### 1.2: Install a Text Editor
-
-- You can use any text editor you like, but I recommend using [Visual Studio Code](https://code.visualstudio.com/)
-- Download and install Visual Studio Code
-- Open Visual Studio Code and install the Python extension
-
-### 2. Tutorial
-
-#### 2.1: Creating a new Python file
-
-- Open Visual Studio Code
-- Click on the "Explorer" icon on the left
-- Click on the "New File" icon
-- Save the file as `square.py`
-
-#### 2.2: Basic Python
-
-- Type the following code in `square.py`:
-
-```python
-print("Hello, World!")
-```
-
-- Open a terminal and navigate to the folder where `square.py` is located
-- Type `python square.py` to run the program
-- You should see `Hello, World!` printed in the terminal
-
-#### 2.3: Using Loops
-
-- Type the following code in `square.py`:
-
-```python
-for i in range(5):
-    print("Hello")
-```
-
-- Run the program again
-- You should see `Hello` printed 5 times in the terminal
-
-#### 2.4: Using Functions
-
-- Type the following code in `square.py`:
-
-```python
-def print_hello(size):
-    for i in range(size):
-        print("hello")
-
-print_hello(5)
-```
-
-- Run the program again
-- You should see `Hello` printed 5 times in the terminal
-
-#### 2.5: Getting Input from the User
-
-- Type the following code in `square.py`:
-
-```python
-def print_hello(size):
-    for i in range(size):
-        print("hello")
-
-size = int(input("Enter the size of the square: "))
-print_hello(size)
-```
-
-- Run the program again
-- You should see `Hello` printed X times in the terminal
-- Replace `X` with the number you entered
-- If you entered `5`, you should see `Hello` printed 5 times in the terminal
-
-## Project Overview
-
-Your task is to write a program that prints a Staircase of a given size. The program should take the size of the Staircase as input from the user and print the Staircase accordingly.
-
-### Requirements
-
-- The program should take the size of the Staircase as input from the user
-- The program should print a Staircase of the given size
-
-Example:
-```bash
-*
-**
-***
-****
-*****
-```
-
-- The program should use a function to print the Staircase
-- The program should use loops to print the Staircase
-- The program should be written in Python
-
-### Bonus
-
-- The program should print both sides of the staircase.
-
-Example:
-```bash
-    * *
-   ** **
-  *** ***
- **** ****
-***** *****
-```
-
-## Submission Guidelines
-
-- The app should be pushed to Github and a pull request should be created. You can check how to push your code to Github in section [2.1.2 Add Changes](https://github.com/Programming-Club-IAU/git-and-github#212-add-changes).
-- The pull request title should be in the following format: `<your-name> - <project-name>`. You can check how to make a pull request in section [2.1.5. Create a pull request](ttps://github.com/Programming-Club-IAU/git-and-github#215-create-a-pull-request).
-- The pull request description should contain the following:
-  - A description of the changes made.
-  - A screenshot of the app running in the terminal.
