+## Building with Clang
+
+To build GregsBestFriend with Clang using mingw64, follow these steps:
+
+1. Download and install [mingw-w64](http://mingw-w64.org/doku.php/download) for your system.
+2. Open the mingw-w64 terminal or command prompt.
+3. Navigate to the `clang++` folder in the GregsBestFriend repository.
+4. Run the following command to build the executable with Clang:
+
+clang++.exe -s -Os GregsBestFriend.cpp -o GregsBestFriend.exe
+
+Here's what each flag does:
+
+- `-s`: Strip the executable of all symbol table and relocation information, reducing its size.
+- `-Os`: Optimize the executable for size. This flag tells Clang to prioritize reducing the size of the generated code over its execution speed.
+
+5. The resulting `GregsBestFriend.exe` executable should be located in the `clang++` folder.
+
+Note that adding your own shellcode to GregsBestFriend may cause the program to be detected by some AV/EDR systems, depending on the specifics of your shellcode. To add your own shellcode, follow these steps:
+
+1. Open the `GregsBestFriend.cpp` file in your preferred code editor.
+2. Locate the `shellcode()` function, which contains the shellcode that will be executed when the program runs.
+3. Replace the existing shellcode with your own shellcode. Make sure that the shellcode is in the form of a byte array, where each byte is represented in hexadecimal format.
+4. Save the changes to the `GregsBestFriend.cpp` file.
+5. Follow the instructions for building the executable with Clang. Once the executable is built, your shellcode will be executed when the program runs.
