-# Syntax
-> This language is still in development, the syntax can be changed at anytime.
-
-Hazure is a [free-form](https://en.wikipedia.org/wiki/Free-form_language) syntax style, so the indentation is purely for readability.
-
-```sml
-fun main: void = do
-    @write("Hello, World!");
-end;
-```
-
-is the same as
-
-```sml
-fun main: void = do @write("Hello, World!"); end;
-```
-
-Hazure is also [expression-oriented](https://en.wikipedia.org/wiki/Expression-oriented_programming_language) like OCaml. There are currently 10 expressions:
-
-1) Comment
-    ```
-    -- Comment!
-    -{ Block Comment }-
-    ```
-2) Values / Types
-    ```sml
-    1
-    true
-    "string"
-    variable
-    ```
-3) Unary and Binary
-    ```sml
-    1 + 2
-    !true
-    ```
-4) Call and Intrinsic. Intrinsic starts with a `@`
-    ```sml
-    @write("Hello")
-    foo("bar")
-    ```
-5) Pipeline
-    ```sml
-    "Hello, World" |> @write(_)
-    ```
-6) Variable declaration
-    ```sml
-    let foo: int = 727;
-    let bar: string = "Hi";
-    let baz: boolean = true;
-    ```
-7) Function declaration
-    ```sml
-    fun foo: void = @write("void returns nothing");
-    fun bar (x: int): int = x + 1;
-    fun baz (x: int) (y: int): int = x + y;
-    ```
-8) If conditions
-    ```sml
-    let cond: bool = true;
-    if cond then
-        @write("True");
-    else
-        do
-            @write("False");
-        end;
-    end;
-    ```
-9) Case matching
-    ```sml
-    match 1 + 1 with
-        | 2 -> @write("Yes");
-        | else @write("How?");
-    end;
-    ```
-10) Do notation. It allows you to have multiple expression because something like right hand side of the function declaration `fun a: int = ...` can only have 1 expression. Do allows you to bypass that.
-    ```sml
-    do
-        @write("Hello, World");
-        foo(bar);
-        let baz: int = 6 + 10;
-    end;
-    ```
-
-Hazure isn't a scripting language, so, you will need a main function.
-
-```sml
-fun main: void = do
-    @write("Hello, World");
-    @write(34 + 35);
-end;
-```
