We'll start by going through the key attributes of C#, syntax basics, and introduce you to OOP. In each section, we'll link you to some quick in-browser C# challenges so you can apply these concepts.

 # Language attributes
+
 C# is a strongly typed, compiled, object oriented language. Let's break this down.
+
 ## Strongly typed
+
   In a **strongly typed** language, every variable has a defined type. Some of these types include:
+
 * String, "Hello world!"
 * Char, 'a'
 * int, 3

 ## Compiler
+
 A **compiler** converts the code you write into a format that your computer can understand. After you write C# and build it, the C# compiler (called Roslyn) will analyze your code to check for any errors.

 # The basics
+
 ## 🌍 Hello World
+
 Here's a piece of code that will print "Hello world!" to the console.
 
 ```csharp
@@ -35,16 +43,20 @@ Console.WriteLine("Hello world!");
 ```
 
 ## Keywords
+
 With C#, you use keywords like `using` and `Console`.
 **Keywords** are predefined, reserved identifiers that have special meanings to the compiler.
 
 ## Accessing methods
+
 The `. (DOT)` in `Console.WriteLine` allows us to access methods and properties. In this example, `Console` is a type that represents the console window. `WriteLine` is a method of the Console type that prints a line of text to that text console.
 
 ## Parameters
+
 In this example, we use parentheses pass a string as a parameter to `Console.WriteLine`.

 ## Variables
+
 In C#, **variables** allow you to temporarily store a value in memory. In C#, you must declare a variable before using it.
+
   ```csharp
   var cSharp = "really cool";
   ```
+
 In this example, we created a string called `cSharp`. You can use the var keyword to declare local variables without explicitly giving them a type.
   
 Variable names can contain alphanumeric characters and underscores, but no special characters. They also cannot be keywords.

 # Syntax cheat sheet
+
 ## Semicolons
+
   Every statement is ended by a semicolon
+
    ```csharp
    Console.WriteLine("there is a ';' at the end of this statement");
    ```
+
 ## Comments
+
   You can make comments by using 2 slashes
+
    ```csharp
    // this is a comment is C#
    ```
+
 ## Case sensitive
+
   C# is case sensitive! For example, a variable "cat" is completely different from a variable "CAT".
+
 ```csharp
 var cat = "meow";
 ```
+
 ```csharp
 var CAT = "rawr";
 ```

 ## Decision logic
+
 In C#, you can build applications that employ decision-making logic so that your application performs different instructions based on a set of conditions. One way we do this is with an `if` statement. `if` statements are made up of three parts:
+
 * The if keyword
 * A Boolean expression between parenthesis ()
 * A code block defined by curly braces { }
 
 If there are multiple condition, you can utilize the `else if` and `else` statements. Basically, if the `if` statement fails, these other statements allow you to test against other conditions.
 You can imagine this in the context of a rock⛰️-paper📃-scissors✂️ game. Imagine you chose rock⛰️.
+
 * `if` your opponent chooses scissors✂️, then you will win
 * `else if` your opponent also chooses rock⛰️, then you will tie
 * `else` your opponent chooses paper📃, then you will lose
 
 Each possible decision your opponent could make leads to a different outcome.

   Booleans are expressions that return either `true` or `false`. They are often used to compare two or more things.

 # Object Oriented Programming
+
 C# is an object-oriented language. 
 Objects are defined by **Classes**. In other words, an **Object** is an instance of a class.
 One way to think about this is that a class is like the blue prints for a house. The actual house that is built is an objects because it is an instance of this blue print.
 
 ## Properties and methods
+
 Objects inherently have attributes. In C# we call these **properties**. The attributes of a house may be the number of doors, what color the house is painted, etc.
 
 We can also define **methods** which describe what an object can do. For example, you can sell your house.

 ## The .NET Class Library
+
 C# also has built in classes and functionality within the .NET Class Library. The .NET Class Library is a collection of thousands of classes containing tens of thousands of methods. These methods are created by Microsoft and are available for use in your applications. For example, when we called `Console.WriteLine` earlier, we were calling a method from the `System.Console` class. For a more in-depth overview, you can read up on the .NET Class Library in the [.NET documentation](https://docs.microsoft.com/dotnet/standard/class-library-overview).
