-
-**PCC Compiler** is a custom programming language compiler built from scratch in C++. It translates PCC code into x64 Assembly (NASM), which is then linked into a standalone Windows executable.
-
-## 🚀 Features
-- **Custom Syntax**: C-like syntax easy for beginners.
-- **Variables**: Support for `int`, `bool` and `string`.
-- **include files**: you can include base files from compiler `#include <main.pcc>` or your own files `#include "myfile.pcc"`.
-- **Control Flow**: `if` statements support.
-- **Functions**: Define and call `void` functions.
-- **Native Compilation**: Compiles directly to x64 machine code.
-
-## 🛠️ Usage
-1. Download the latest release from the [Releases](../../releases) page.
-2. Unzip the archive to C:/PCC/
-3. Run `start.bat` as Administrator.
-4. Compile your code: `PCC.exe code.pcc`.
